2025 Smartwatch Showdown: Google Pixel Watch 4 vs Galaxy Watch 7 vs Apple Watch Series 10 – Which Reigns Supreme?

Design & Display: Classic Circle or Iconic Square?

Each flagship smartwatch has a distinct look and build. Google’s Pixel Watch 4 continues with a minimalist circular design inherited from its predecessors tomsguide.com. Leaked renders suggest slimmer bezels and a larger usable screen area than before, while possibly a slightly thicker case to house a bigger battery tomsguide.com tomsguide.com. Google is offering two case sizes (41mm and 45mm) for the first time – both featuring a sharp Actua 360 OLED display peaking at an extremely bright 3,000 nits androidauthority.com. That’s 50% brighter than the Pixel Watch 3’s screen, which hit 2,000 nits androidauthority.com. The Pixel Watch 4’s display is designed for great outdoor visibility, and it retains the trademark domed glass look and digital crown. An extra physical button is rumored on the Pixel Watch 4’s casing, likely to improve usability tomsguide.com. Build materials remain premium, with stainless steel or similar housing, and Google has reportedly improved the watch’s reparability as well tomsguide.com.

Samsung’s Galaxy Watch series sticks with a round watch face, mirroring a traditional timepiece. The Galaxy Watch 7 (2024) shares the same basic design as the prior Watch 6 – a high-res AMOLED circular display, two side buttons, and a relatively slim profile tomsguide.com. In 2023 Samsung reintroduced the physical rotating bezel on the Galaxy Watch 6 Classic, but in 2024 the Watch 7 did not get a “Classic” variant – Samsung instead launched a rugged Galaxy Watch Ultra alongside it braceletsmartwatch.fr. So, the standard Galaxy Watch 7 has a clean bezel (with a touch-sensitive digital rotating border) and comes in 40mm and 44mm sizes braceletsmartwatch.fr. It uses durable Sapphire Crystal glass on the display for scratch resistance samsung.com. Samsung’s new Galaxy Watch 8 (2025), just unveiled, brings back a Classic model with the beloved rotating bezel, catering to those who prefer that tactile control tomsguide.com tomsguide.com. Both Watch 7 and Watch 8 have vibrant AMOLED screens; the Watch 7’s brightness was already excellent, and the Watch 8 reportedly pushes it further while also integrating advanced AI features (more on that later) tomsguide.com. In terms of build, Samsung offers aluminum or stainless steel cases on regular models, while the Ultra has a tougher titanium body for outdoor durability braceletsmartwatch.fr braceletsmartwatch.fr. The Watch 7 is rated 5 ATM + IP68 (water-resistant to 50m) and the Ultra to 10 ATM (100m), so they can handle swims and more tomsguide.com. Samsung’s style is less “techy” looking than Apple’s – one reviewer noted the round Galaxy Watch “doesn’t necessarily look like a smartwatch at first glance” and can pass as a regular watch more easily than a square display tomsguide.com.

Apple’s Watch Series 10 (2024) stands out with Apple’s signature rectangular curved-edge display. In a big design update, Series 10 got larger screen sizes (approximately 42mm and 46mm cases, up from 41/45mm) with much slimmer bezels macrumors.com macrumors.com. Apple calls it their largest, most advanced display ever – in fact, the 46mm Series 10’s screen is even bigger than that of the Apple Watch Ultra 2 macrumors.com macrumors.com. Despite the bigger display, the Series 10 is the thinnest Apple Watch to date, about 10% thinner than Series 7/8/9, making it very sleek on the wrist apple.com apple.com. The always-on OLED display can hit 2,000 nits brightness (like Series 8/9 did) but now uses a new LTPO OLED that’s more power-efficient at lower refresh rates macrumors.com. Impressively, Apple enabled the always-on second hand: the Series 10’s screen can refresh once per second in standby (versus once per minute before) – so you see a live ticking second hand without raising your wrist apple.com apple.com. In terms of build, Apple introduced new case materials: aluminum or titanium (no stainless steel option this generation) in various finishes apple.com macrumors.com. The Series 10’s back is now metal instead of ceramic, integrating the antenna into the back cover for a seamless look macrumors.com apple.com. As always, the Apple Watch has a precision Digital Crown and side button. It’s rugged too: crack-resistant front crystal, IP6X dust protection, and WR50 water resistance (swimproof) macrumors.com. Apple even added the depth gauge and water temperature sensor that were previously exclusive to the Ultra, so Series 10 can measure depth (up to ~6m) and water temp for snorkeling or swimming macrumors.com macrumors.com. The Apple Watch keeps its squarish face – great for displaying text and app interfaces – which remains an iconic design differentiator in a sea of round smartwatches.

Software & Ecosystem: Wear OS vs One UI Watch vs watchOS

These watches run three different operating systems, each with its own ecosystem and phone compatibility. Google’s Pixel Watch 4 runs Wear OS (Google’s smartwatch platform), likely launching with the latest Wear OS 5 (as Pixel Watch 3 received 5.1 in early 2025). The Pixel Watch is Android-only – you need an Android phone (Android 9 or above) to set it up, and there’s no iOS support support.google.com. This is analogous to Apple’s approach, effectively keeping Pixel Watches within the Android ecosystem (just as Apple Watches only work with iPhones). The benefit is tight integration with Google’s services: Pixel Watch 4 will leverage the latest Google Assistant (codename “Gemini”) AI on your wrist androidauthority.com androidauthority.com. In fact, it’s expected to debut Google’s new Gemini voice assistant built-in, enabling powerful AI responses and on-device processing for faster queries tomsguide.com. A leak shows you can simply raise your wrist and speak to “Gemini” for personalized help and even AI-generated message replies that mimic your style androidauthority.com. Being a Wear OS watch, Pixel Watch 4 should have full access to the Google Play Store for third-party watch apps (from fitness apps like Strava to music, messaging, maps, and more). Google also integrates Fitbit’s platform deeply (since it owns Fitbit): health data syncs to the Fitbit app, and Pixel Watch buyers get Fitbit Premium trials store.google.com store.google.com. That means advanced analytics in the Fitbit app and features like Daily Readiness (more on fitness below). In terms of smartphone integration, Pixel Watch pairs best with Google’s own Pixel phones (for features like Camera remote control or Fast Pair), but it will work with any modern Android phone. It supports standard features like Bluetooth calling, message notifications, Google Wallet payments (NFC), turn-by-turn navigation with Google Maps on the watch, etc., regardless of the Android device.

Samsung’s Galaxy Watch 6/7/8 run Wear OS as well, but with Samsung’s One UI Watch skin on top. Samsung partnered with Google to use Wear OS (starting from Galaxy Watch 4 onward), which means Galaxy Watches also have the Google Play app ecosystem and can run the same apps as Pixel Watch. However, Samsung preloads its own apps and services: Samsung Health for fitness, Samsung Pay (Wallet), Bixby voice assistant (with option to use Google Assistant), and a generally Samsung-styled UI. The One UI Watch interface integrates tightly if you use a Samsung Galaxy phone – for example, settings and Do Not Disturb sync between phone and watch, and health features like ECG and blood pressure tracking require a Samsung phone to enable in many regions tomsguide.com. In fact, while Galaxy Watches will technically work with any Android phone (they do not support iPhones either), Samsung does gate some advanced health functions to its own ecosystem tomsguide.com. As one reviewer noted, “to get the most out of the Galaxy Watch 7 and the latest Galaxy AI health features, you’ll need a Samsung Galaxy smartphone… while the watch will play nice with any Android, you won’t have access to all the best things that set the Watch 7 apart.” tomsguide.com. So non-Samsung Android users can still use Galaxy Watches for basics (notifications, Google apps, etc.), but features like ECG, BP, and some fitness insights might be limited. In terms of voice assistants, Samsung’s default is Bixby, but you can install Google Assistant on the watch and even map it to the long-press button if you prefer samsung.com samsung.com. There’s also Amazon Alexa available via a third-party app (like the Alexa Wear OS app), so Samsung gives flexibility here. The newest Galaxy Watch 8 series (2025) interestingly is branded as the first with Google’s Gemini AI built-in tomsguide.com – indicating Samsung is embracing Google’s next-gen Assistant on Wear OS, likely supplementing (or overshadowing) Bixby. For broader ecosystem, Galaxy Watches integrate with Samsung’s device network (e.g. controlling SmartThings smart home, unlocking Samsung phones, or syncing with Samsung earbuds for seamless audio switching).

Apple’s Watch Series 10 runs watchOS 11 (upgradable to watchOS 12 in 2025) and is firmly an iPhone-only accessory. If you have an iPhone, Apple Watch offers the most seamless integration: automatic Apple ID sync, iMessage and phone calls on the wrist, Apple Pay, Apple Fitness+, and tight coupling with iOS apps (like Maps, Music, HomeKit, etc.). But if you use Android, Apple Watch is not an option at all. Apple’s ecosystem integration is a selling point – for instance, Apple Watch can unlock your Mac, serve as a viewfinder for your iPhone camera, and hand off phone calls or media between devices. The watchOS platform arguably has the richest third-party app selection among smartwatches, thanks to years of developer support. You can download apps from the on-watch App Store or the Watch app on iPhone. Popular apps in health, productivity, and travel often have Apple Watch versions. With watchOS 11/12, Apple also introduced new built-in features like the Smart Stack widgets and improved Watch faces that leverage the larger Series 10 screen apple.com apple.com. Siri is the voice assistant – and on Series 10, Siri can now work on-device for many requests thanks to the S10 chip’s Neural Engine, meaning quicker responses for things like setting timers or dictation without needing internet apple.com. Apple has also been adding more AI-driven features; for example, “Double Tap” gesture lets you tap your thumb and finger to control the watch one-handed, powered by the Neural Engine’s machine learning macrumors.com macrumors.com. However, Apple’s AI efforts are more subtle compared to Google’s Gemini – Apple focuses on things like predictive Siri and health insights rather than a conversational assistant model on the watch. One area Apple excels is the continuity of the ecosystem: the Series 10 has a new ultra-wideband (UWB) chip that enables Precision Find for locating your iPhone or AirTags, and improved Digital Car Key range macrumors.com tomsguide.com. Overall, if you’re an iPhone user, the Apple Watch is tightly woven into the iOS/macOS world, whereas Pixel and Galaxy watches are the go-to for Android users (with Samsung’s best experience on Samsung phones).

Health & Fitness Tracking: Which Watch Has Your Back?

Health and fitness features are the heart of these wearables, and each has strengths. Samsung’s Galaxy Watch has made a name by packing a broad array of health sensors. The Galaxy Watch 7 uses Samsung’s advanced BioActive sensor, which combines multiple functions: PPG heart rate, ECG, SpO₂ blood oxygen, and even BIA (Bioelectrical Impedance Analysis) for body composition tomsguide.com. This means the watch can read your heart rate 24/7, take on-demand ECGs for atrial fibrillation detection, estimate blood oxygen levels during sleep or workouts, and even measure body fat vs muscle (a feature Apple and Google lack). Samsung also enabled blood pressure monitoring on its watches in many countries – it uses the PPG sensor plus periodic cuff calibration to give BP readings (though this requires a Samsung phone and isn’t cleared in the U.S. yet). With the Watch 7, Samsung introduced a host of AI-driven health insights. An upgraded Exynos W1000 chip (3× faster than the old) allows real-time analysis of your data tomsguide.com. The watch generates a Daily Sleep Score and a new “Energy Score”, which combines your sleep quality and recent activity into one number each day tomsguide.com. Reviewers found these scores and tips very motivating – even noting the watch will gently “scold” you for unhealthy habits (like late-night snacks impacting your sleep) by providing specific guidance tomsguide.com. The sleep tracking on Galaxy Watch 7 is especially comprehensive: it logs sleep stages, snoring, blood oxygen variations, skin temperature, movement, heart rate, and respiratory rate, then gives you easy-to-read insights and coaching tomsguide.com tomsguide.com. In fact, Tom’s Guide praised the Watch 7’s sleep analysis detail, saying it “blows other popular wearables out of the water” in volume and depth of data tomsguide.com. A standout feature: the Galaxy Watch 7 is the first smartwatch with FDA-authorized sleep apnea detection tomsguide.com. If enabled, it can detect signs of moderate to severe obstructive sleep apnea by analyzing your blood oxygen and breathing disruptions overnight aasm.org tomsguide.com. After at least two nights of data, the watch will alert you if it finds suspected apnea events, recommending you seek medical advice tomsguide.com. This is a groundbreaking health feature that Samsung beat Apple and Google to (Apple just introduced their own version in Series 10). The Watch 7’s fitness tracking covers 90+ workout modes, automatic exercise detection, and new personalized coaching (e.g. a “Race” widget that lets you challenge your previous run times samsung.com). Thanks to dual-band GPS added in Watch 7, outdoor exercise tracking (runs, cycling, hikes) is extremely accurate – tests showed it even outperformed a dedicated Garmin device in GPS precision tomsguide.com tomsguide.com. Summing it up, a tech reviewer declared “the Galaxy Watch 7 lowkey boasts the most impressive wellness-tracking tech and features of any smartwatch I’ve tested in 2024” tomsguide.com. The only caveat: full use of ECG, blood pressure, etc., requires Samsung’s phone/app as noted. Looking ahead, the Galaxy Watch 8 (2025) builds on this with rumored blood sugar tracking (not yet confirmed) and even deeper AI coaching. Samsung’s July 2025 update expanded the availability of their sleep apnea feature globally news.samsung.com, and there are hints that future Galaxy Watches could integrate noninvasive blood glucose sensing if the tech matures – potentially a game-changer for diabetics.

Google’s Pixel Watch, leveraging Fitbit’s heritage, is a fitness companion with a growing list of health features. The Pixel Watch 4 is expected to include all the sensors from Pixel Watch 3: continuous heart rate (with Fitbit’s acclaimed 24/7 HR algorithm), ECG (introduced in Pixel Watch 1), SpO₂ sensor (the hardware was present before, and should be fully enabled now), and an EDA sensor for stress (Pixel Watch 2 added a continuous electrodermal activity sensor to detect stress responses). Pixel Watch 3 debuted a unique “Loss of Pulse” detection – essentially the ability to detect a sudden cardiac arrest (when your heart stops) and call emergency services automatically tomsguide.com tomsguide.com. Google proudly noted it was the first watch that can detect loss of pulse and alert emergency services store.google.com store.google.com, something even Apple Watch doesn’t explicitly do (Apple watches detect high/low heart rate and falls, but not a flatline pulse). This potentially life-saving feature will of course carry into Pixel Watch 4, likely with improvements. Pixel Watch 4 is also rumored to add a “breathing emergency” detection, which might monitor if you stop breathing (perhaps during sleep, complementing sleep apnea alerts) tomsguide.com. For exercise, Pixel leans on Fitbit’s robust platform: you get 40+ exercise modes with real-time stats androidauthority.com, GPS tracking (Pixel Watch 4 will have built-in GNSS like prior models), and coaching features. The Pixel Watch 4 can even tell you “if your body is ready for an intense workout or if you should focus on recovery,” thanks to a Readiness Score that analyzes your recent sleep, HRV (heart rate variability), and activity androidauthority.com store.google.com. This is essentially Fitbit’s Daily Readiness metric, guiding you to avoid overtraining – Pixel Watch 4 will say whether to push hard or take it easy each day. Runners will appreciate Google’s new AI-powered Running Insights: you can build custom interval workouts and get live guidance with audio and haptic cues during runs store.google.com store.google.com. Pixel Watch 4 also measures advanced running metrics like cadence, stride length, and even vertical oscillation to help improve your form store.google.com store.google.com. Health monitoring includes sleep tracking (with Fitbit’s sleep stages and sleep score), continuous heart rhythm alerts, and likely skin temperature sensing (Pixel Watch 2 had a skin temp sensor, used for nighttime readings). While Google’s health suite was initially a bit behind, they’re catching up fast by incorporating Fitbit’s decade of expertise. Plus, Pixel Watch owners typically get 6 months of Fitbit Premium free store.google.com, unlocking deeper analysis like personalized wellness reports and even AI-driven insights (Fitbit was testing an AI coach feature, which may integrate with the new on-watch Gemini assistant for health Q&A or tips). In summary, Pixel Watch 4 is shaping up to be a well-rounded fitness watch that, thanks to Fitbit DNA, can hold its own against Apple and Samsung in tracking accuracy. It may not have Samsung’s body composition or blood pressure features, but it matches core functions (HR, ECG, SpO₂) and adds unique safety tools. And Google is rumored to be working on satellite-based SOS for wearables, so a Pixel Watch might someday send an emergency message even without phone signal tomsguide.com (a feature Apple introduced on iPhone; Google could extend it to watches via satellite connectivity in the future).

Apple’s Watch Series 10 is often seen as the gold standard for health features, and this generation brought even more. It has the staple sensors: 24/7 heart rate with alerts for high/low HR and irregular rhythm, a single-lead ECG (Apple added ECG back in Series 4), a pulse oximeter for blood oxygen, a wrist temperature sensor (added in Series 8, used for cycle tracking and sleep trends), and a slew of motion sensors that enable things like fall and crash detection. New in Series 10 is official support for Sleep Apnea Notifications apple.com. The watch monitors metrics like blood oxygen dips and respiratory rate variability during sleep, and will now notify you if possible signs of sleep apnea are detected apple.com apple.com. This is similar in aim to Samsung’s feature, though Apple only announced it in 2024 – Samsung’s is FDA-authorized, while Apple’s implementation details (clearance status) aren’t fully public. Nonetheless, Apple emphasizes that WatchOS now tracks key overnight metrics (HR, respiratory rate, O₂, wrist temp) and can alert users to anomalies apple.com. Another area Apple expanded is metrics for outdoor and endurance activities: with the Series 10’s depth gauge and water temp sensor, it effectively gains features for divers and surfers. The new Tides app provides tidal forecasts, and the previously Ultra-exclusive Oceanic+ dive app now works on Series 10, allowing recreational dive tracking for depths up to 6m macrumors.com macrumors.com. Runners and cyclists also got updates in watchOS, like power zone training, custom workouts, and even the ability to connect Bluetooth cycling sensors introduced in 2023. Apple’s health insights have grown more holistic: the iPhone Health app will create trends and even now track mental health (mood logging) and vision health, with the watch contributing data (like ambient light for screen time). However, one notable setback: due to an ongoing legal battle with Masimo, blood oxygen monitoring was disabled on Series 10 in the U.S. at launch tomsguide.com (Masimo claims patent infringement on Apple’s SpO₂ tech). Apple Watch still has the SpO₂ sensor hardware, and outside the U.S. it functions normally – but U.S. customers currently can’t use the blood oxygen app until that dispute resolves tomsguide.com. Looking to the future, Apple is reportedly working on blood pressure monitoring for Apple Watch (possibly using optical sensors to detect pressure waveforms). Rumors strongly suggest blood pressure alerts will debut in Apple Watch Series 11 (2025), which could warn users of hypertension risks tomsguide.com. This would be huge, as hypertension often goes undiagnosed – nearly 13% of worldwide deaths are linked to high blood pressure tomsguide.com tomsguide.com. Apple is likely to implement it in a user-friendly way, notifying if your baseline readings trend high. As for the holy grail of glucose monitoring, that still seems distant – noninvasive glucose tracking “still a long way off” for Apple tomsguide.com. Additionally, Apple has explored adding a camera to the Apple Watch. A future model might hide a tiny camera in the top bezel or even the Digital Crown, enabling FaceTime or Visual ID features tomsguide.com. If Series 11 or Ultra 3 includes a camera, it could open the door to new health applications (like snapping a meal for calorie AI analysis, or simply wrist selfies). For now, Series 10 and its watchOS deliver extremely polished health tracking – an expert reviewer called it “the best Apple Watch for most people, offering all of the latest health features” macrumors.com, including ECG, sleep stages, cycle tracking, and more. Apple’s long-term advantage is the integration of data: your Apple Watch data flows into the Apple Health app, where it can be securely shared with doctors or aggregated with health records. Plus, features like Crash Detection and Fall Detection on Series 10 use upgraded sensors and algorithms to automatically call SOS if you’re in a severe car accident or take a hard fall and don’t move apple.com apple.com. All three watches can potentially save your life, but Apple’s and Google’s focus is more on fall/crash/pulse SOS, while Samsung is breaking ground in preventative alerts like sleep apnea.

Battery Life & Charging: All-Day Use or Multi-Day Marathon?

Battery life is the Achilles’ heel for many smartwatches, especially with always-on displays and 24/7 tracking. Apple’s Watch Series 10 famously maintains the same baseline as its predecessors: about 18 hours per charge in normal use apple.com apple.com. Apple calls this “all-day battery life,” essentially meaning you charge it nightly. In real terms, you can usually get through a full day (morning to bedtime) with some buffer. Series 10 did not increase battery capacity, and the move to a thinner design suggests battery size might have even slightly shrunk, but efficiency gains kept it similar to Series 9. If you turn off always-on display and use the Low Power Mode, you can stretch it to around 36 hours, but with many features disabled. Where Apple did improve is charging speed: Series 10 is the fastest-charging Apple Watch yet apple.com. Thanks to a larger, more efficient charging coil and optimized internals, it can charge to 80% in about 30 minutes apple.com apple.com. That’s great for top-ups – for example, you can plop it on the charger while showering and dressing, and get enough juice for another full night of sleep tracking. Apple clearly designed it this way so users could charge briefly in the evening or morning and wear it overnight for sleep data apple.com apple.com. The Series 10 still uses Apple’s magnetic charging puck (USB-C cable) and does not support true Qi wireless charging on arbitrary pads (the charger is a custom MagSafe-like implementation).

Samsung’s Galaxy Watch 7 offered similar endurance to its predecessor – generally 1 to 2 days of use on a charge, depending on settings. The Watch 7 kept the same battery capacities as Watch 6 (around 300 mAh in 40mm, 425 mAh in 44mm) tomsguide.com tomsguide.com. In testing, the 40mm Watch 7 got roughly 24 hours with the always-on display on and all features active tomsguide.com tomsguide.com. With a power-saving mode (disabling AOD, etc.), it managed about 40 hours tomsguide.com. In other words, most users can expect about every-other-day charging on Galaxy Watch 7 tomsguide.com. The larger 44mm model typically lasts a bit longer (closer to 30-36 hours default). While this is on par with Pixel Watch and better than Apple, it’s still far from multi-week trackers like Garmin. A full charge of Galaxy Watch 7 takes around 2 hours tomsguide.com – not especially fast. Samsung did not highlight a major charging speed boost for Watch 7, though the charger is wireless (using a magnetic puck that supports Qi-based charging for some models). The Galaxy Watch 8 in 2025 reportedly bumps battery size slightly and, more importantly, Samsung claims improved efficiency with the new chipset and display. We’ve seen rumors of better battery life on Watch 8 despite brighter screens, possibly by using more efficient OLED panels and smarter CPU cores. Still, any improvements are likely incremental – maybe adding a few hours. The Watch 8 also now supports Qi-standard wireless charging, meaning you could use some phone reverse wireless charging or standard pads (the Pixel Watch 4 is rumored to do the same tomsguide.com, which would be convenient). One advantage for Samsung: the Galaxy Watch Ultra model has a much larger battery (~590 mAh) tomsguide.com, yielding 3+ days easily. But that’s a different class of watch (and a bulky one). For the standard Galaxy Watch series (and Pixel/Apple watches), multi-day battery with everything on remains elusive.

Google’s Pixel Watch 4 is making strides in battery life. The Pixel Watch 1 was criticized for barely 24h of life; by Pixel Watch 3 (with a larger 45mm model), Google achieved up to 48 hours (in the larger version) under optimal settings tomsguide.com tomsguide.com. The Pixel Watch 4 leak indicates the 41mm model will last ~30 hours with always-on display (AOD) enabled, and the 45mm model around 40 hours with AOD on androidauthority.com. Those are substantial gains, likely thanks to a more efficient chipset and a slightly bigger battery (rumored ~15% capacity increase) tomsguide.com tomsguide.com. In fact, sources say the 45mm Pixel Watch 4 has a 459 mAh battery (up from 420 mAh in the Pixel Watch 3 45mm) tomsguide.com tomsguide.com. With AOD off or in a lighter-use scenario, the 45mm could potentially hit 2-3 days on a charge – one report speculates up to 72 hours for the big model if you’re conservative tomsguide.com tomsguide.com. The 41mm might do about 36 hours with AOD off. This is a notable improvement that would put Pixel Watch 4 ahead of Galaxy Watch for battery stamina. Charging is also improved: Pixel Watch 4 is said to support 25% faster charging with a new Quick Charge dock androidauthority.com. Pixel Watch 2/3 already used a magnetic pogo-pin charger; Pixel Watch 4 may switch to true wireless charging (Qi) that can also charge on a Pixel phone’s reverse wireless charge pad tomsguide.com. Being able to just drop it on any Qi charger – if confirmed – would be a nice convenience over proprietary chargers. With the quick-charge, you might get ~50% charge in 30 minutes (Pixel Watch 3 could do ~50% in ~30min as well), and a full charge likely in under 80 minutes. Google knows battery life is a pain point, so Pixel Watch 4’s thicker case is a worthwhile trade-off if it means more endurance tomsguide.com tomsguide.com. All in all, Pixel Watch 4 and Galaxy Watch 7/8 are roughly comparable in battery life (1.5 days typical), both now outlasting Apple Watch’s one-day battery. Heavy LTE use or GPS workouts will drain any of these faster – expect about 5-6 hours of continuous GPS tracking on Galaxy or Pixel (enough for a marathon), and maybe 7-8 hours on Apple (Apple tends to optimize GPS well, but battery is smaller). It’s always wise to charge daily if you use the watch for sleep tracking. The good news: all three have solutions for quick top-ups, whether it’s Apple’s 80%-in-30-min, Google’s fast charge dock, or Samsung’s ability to charge on the back of a Galaxy phone wirelessly.

Smart Features & Apps: Beyond Fitness (Music, Payments, Voice, and More)

Modern smartwatches are mini smartphones on the wrist. All three watches offer core “smart” features like notifications mirroring your phone, music playback control, contactless payments, voice assistants, GPS navigation, and optional LTE for standalone connectivity. The differences lie in ecosystems and extra bells and whistles:

• Voice Assistants: Apple Watch uses Siri, tightly integrated with iOS. Siri handles dictation, sending messages, setting reminders, smart home control, etc. On Series 10, Siri requests for health data (like “what’s my heart rate?”) can be processed on-device, making them faster and private apple.com. Siri’s functionality is steady, though generally considered a bit less “smart” than Google’s assistant in answering general queries. The Pixel Watch 4 will have the new Google Assistant (Gemini), which is expected to be far more conversational and powerful, essentially putting Google’s latest AI on your wrist androidauthority.com androidauthority.com. This could enable things like asking follow-up questions, getting summaries, translations, or personalized recommendations via voice. On current Pixel Watches, Google Assistant can already do things like control Nest devices, handle texts, or run Google searches. Samsung offers Bixby out of the box – which can do watch-specific commands reliably (start a workout, call a contact, etc.) but isn’t as robust for general knowledge questions. However, you can enable Google Assistant on Galaxy Watch easily and make it the default with a press-and-hold of a button samsung.com samsung.com. Some users even run Amazon Alexa on Galaxy Watches via an app, giving a third option. So, Samsung arguably offers the most flexibility in voice assistants (Bixby, Google, Alexa), Google’s watch focuses on Google Assistant only, and Apple’s focuses on Siri only.
• Cellular & Calls: All three have models with optional 4G/LTE cellular connectivity. With an LTE-enabled watch (and an active add-on plan), you can leave your phone behind – the watch can make/receive calls with its built-in microphone and speaker, send messages, stream music, and run apps using mobile data. Apple’s cellular watches use an eSIM linked to your iPhone’s number (calls come through as if it’s your phone). Samsung and Google watches similarly can mirror your phone number (Android’s “Number Sharing” on supported carriers). A neat promo: Google is offering 2 years of free LTE data on Google Fi if you buy a Pixel Watch 4 LTE model androidauthority.com – a great perk for connectivity androidauthority.com. Call quality on all is decent for short calls; Apple’s newer models have an improved speaker and mic array for clearer calls. Do note, using LTE significantly increases battery drain – if you’re on cellular actively, expect battery life to drop.
• Music and Apps: Apple Watch can store music/playlists (like from Apple Music or Spotify) and stream over Wi-Fi/LTE to Bluetooth earbuds. Samsung and Pixel do the same via Spotify, YouTube Music, etc. Each has Bluetooth for connecting earbuds or headphones. All support on-board music storage (Apple has 64GB in Series 10 macrumors.com macrumors.com, Samsung doubled storage to 32GB on Watch 7 tomsguide.com tomsguide.com, Pixel Watch 4 likely has 32GB as well). App-wise, Apple’s App Store offers apps like Audible, Google Maps, Spotify, Outlook, and many fitness apps tailored for watchOS. Wear OS (Pixel & Samsung) has its Play Store with growing offerings – including Google Maps (which allows turn-by-turn directions on the watch without your phone), Google Wallet, Gmail, Spotify, Strava, and many more. One standout: Google Maps on Wear OS is excellent for navigation if you want to get directions on your wrist while walking or driving, and it works on LTE too (Apple Maps on Apple Watch provides similar functionality for iPhone users). Apple Watch has some unique tricks like Walkie-Talkie (push-to-talk voice messages with friends who have Apple Watches) and tight integration with iMessage (you can send voice notes, scribbles, or use preset smart replies easily). Google and Samsung watches are more reliant on voice or the tiny keyboard for replies, though Wear OS now offers a full QWERTY keyboard for typing or swipe-typing responses on the watch – handy in a pinch. Apple still uses dictation, scribble, or canned responses, since there’s no software keyboard on watchOS by default (third-party keyboard apps exist, but not widely used).
• Payments: All support tap-to-pay: Apple Watch with Apple Pay, Galaxy Watch with Samsung Pay (or Google Pay if you install it), and Pixel Watch with Google Wallet. So you can buy groceries or transit rides with a flick of the wrist on any of them. Apple and Google use NFC; Samsung’s can use NFC and in some older models had MST for legacy terminals (but MST is no longer in recent models).
• Notifications & Messaging: All watches show your phone’s notifications and allow some form of quick reply. Apple Watch is tightly integrated with iMessage and the iPhone’s notification center; you can dictate replies or send emojis, etc. Pixel and Galaxy Watches show Android notifications; with Android’s rich notification system, you often can see images, emails, etc., and take actions (archive an email, like a tweet, etc.). If you’re a heavy communicator, Apple’s advantage is the seamlessness with iPhone’s messaging and the reliability of iMessage on the watch. Android watches are catching up, especially with the new Wear OS Tiles and Gmail/Calendar integration, which let you see upcoming events or emails at a glance.
• Unique Smart Features: Apple Watch has a few unique tricks like ECG apps that generate PDF results you can share with your doctor, a built-in Compass app with Backtrack for hikers, and the ability to trigger your iPhone’s camera for group photos. It also now has an on-device Translate app (as of watchOS 11) so you can speak and see translations on the watch apple.com apple.com. Samsung’s watches can integrate with SmartThings to control smart home devices right from your wrist (turn off lights, etc.), and Samsung includes various gesture controls (e.g., answering calls by clenching fist). Pixel Watch, being relatively new, is adding features rapidly – one spotlight for Pixel Watch 4 is the “raise to talk” gesture to activate the Assistant hands-free androidauthority.com. Also, Pixel Watch will benefit from Android’s new Wear OS enhancements, like better calendar sync and even emergency SOS via satellite (planned) as mentioned.

Overall, in terms of apps and ecosystem, Apple Watch still enjoys the most mature third-party app selection and accessories. But Google’s and Samsung’s adoption of a unified Wear OS means developers are more likely to build apps that work on Pixel and Galaxy watches alike, which is boosting the catalog. If you’re deep into Google’s ecosystem (Gmail, Google Assistant, YouTube Music), a Pixel Watch will feel like a natural extension of your phone on your wrist. If you’re a Samsung Galaxy phone user, the Galaxy Watch is almost a no-brainer to maximize what you can do (and it still can use all Google apps too).

One more smart feature category to mention: safety and emergency functions. All three watches have fall detection that can auto-call emergency services if you take a hard fall and don’t move store.google.com. Apple and Google also have Emergency SOS features where holding a button can call 911 (or region equivalent) and alert your emergency contacts. Apple’s Series 10 and Pixel Watch 3/4 also have car crash detection, leveraging accelerometers and sound to detect a severe car accident and automatically call help apple.com apple.com. Samsung hasn’t explicitly marketed crash detection, but its fall detection can be configured for high-impact events which might cover some crashes. Additionally, Apple and Google watches allow you to share Medical ID info with first responders (Apple via the iPhone Health app linkage, Pixel via emergency info in the watch) store.google.com. These kinds of smart features underscore how these devices are not just gadgets – they actively work to keep you safe in the background.

Price & Value: How Much Will They Cost You?

In terms of pricing, each brand targets a slightly different range, but all have multiple configurations. Starting with Google Pixel Watch 4, leaks suggest Google is sticking close to previous pricing: a starting price around $349 for the base 41mm Bluetooth model tomsguide.com. If Google follows last year, that’s likely $349 for 41mm Wi-Fi/GPS, and around $399 for the larger 45mm (non-LTE) tomsguide.com tomsguide.com. LTE-capable versions typically add about $50. Google might adjust prices upward a bit (rumors said possibly +$50) since Samsung bumped their prices this year tomsguide.com tomsguide.com, but as of now $349–$399 is the expectation, with LTE models in the ~$399–$449 range. Google often includes promotions (like the 2-year data on Google Fi androidauthority.com, or bundle discounts with Pixel phones). Pixel Watch 4 sits at a premium price point, similar to Apple’s base models, but Google is positioning it as a top-tier smartwatch and one of the “best Android smartwatches money can buy” tomsguide.com.

Samsung’s Galaxy Watch offers more variety in pricing because of size and model options. The Galaxy Watch 7 launched at the same price as Watch 6, starting around $299 for the 40mm Bluetooth version in the US braceletsmartwatch.fr braceletsmartwatch.fr (£289 in the UK). The 44mm Bluetooth was about $329, and LTE versions roughly +$50 each (so ~$349 for 40mm LTE, ~$379 for 44mm LTE) braceletsmartwatch.fr braceletsmartwatch.fr. Samsung kept prices steady in 2024, which was good value considering the tech inside. The new Galaxy Watch 8 (2025), however, saw a slight increase – Samsung raised prices by about $50 on the Watch 8 series according to reports tomsguide.com. So if Watch 7 was $299, Watch 8 might start around $349. Samsung also has the Galaxy Watch Ultra line: the 2024 Watch Ultra was priced around $799 (£599 in UK) braceletsmartwatch.fr, targeting the high-end segment (similar to an Apple Watch Ultra competitor). The Galaxy Watch 8 Classic (2025) effectively replaces the Ultra in some markets or sits between standard and Ultra – its pricing is likely around $449-$499. For this comparison, focusing on the mainline Galaxy Watch, you’re looking at approximately $300-$380 depending on size and LTE. Samsung often discounts its watches or bundles them with phone pre-orders (e.g., getting a Watch for half price with a Galaxy phone). In terms of value, Samsung’s watches are slightly cheaper than Apple’s for similar sizes, and they undercut Google’s Pixel Watch by about $50 at base price. Given the robust health features and premium build (sapphire glass, etc.), many consider Galaxy Watch the best value for Android users. One tech reviewer noted that despite a lack of flashy design changes, the Galaxy Watch 7’s feature set — especially in health tracking — makes it a great value proposition in 2024 tomsguide.com tomsguide.com.

Apple’s Watch Series 10 is priced at Apple’s usual premium. It starts at $399 for the base 42mm aluminum GPS-only model macrumors.com. The larger 46mm aluminum is $429. If you want the cellular-capable versions, they typically add $100 in Apple’s lineup (so roughly $499 for 42mm LTE, $529 for 46mm LTE). Titanium cases (which come by default with cellular) are pricier: the Series 10 in titanium started around $799 and up, similar to prior stainless steel pricing. Apple also has the Apple Watch SE (budget model, $249) and the Ultra 2 ($799) as alternate options. But head-to-head, Apple Watch Series 10’s entry price is a bit higher than Pixel or Samsung’s base models. However, Apple justifies it with the seamless iOS integration and strong resale value. Apple Watches tend to hold value better in resale or trade-in, which can offset the cost for those who upgrade frequently. Another thing: Apple includes 3 months of Fitness+ and Apple Music for free with new watches, and recently has pushed carbon-neutral models with certain band choices (not a monetary value per se, but an angle for environmentally conscious buyers). Ultimately, if you’re in Apple’s ecosystem, the price is the price – and for many, the “best smartwatch for most people” (Series 10) is worth that $399 macrumors.com macrumors.com.

In comparing value for money, Android users have the benefit that Samsung often discounts its watches aggressively a few months after launch. Pixel Watch is a bit more niche but Google has offered deals (for instance, Pixel Watch 3 saw price cuts and package deals with Pixel phones). Apple products are rarely discounted beyond maybe $30-50 on sale. If you factor in features per dollar: the Galaxy Watch 7/8 arguably gives the most bang for buck (advanced health sensors like body composition and FDA-approved features at $299-$349). Pixel Watch 4 will offer cutting-edge AI and premium design, but at roughly $349 it’s a bit more expensive for similar core capabilities, essentially charging for the refined Google experience and Fitbit integration. Apple charges the most, but also delivers the most polished ecosystem experience and build quality. Depending on your smartphone platform, your “value” equation might already be decided (no point in a “cheaper” Apple Watch if you use Android, and vice versa). The good news is that all three have options at different price points: smaller sizes or Wi-Fi only to save money, and higher-end editions (like titanium or Ultra) if you want to spend more.

Release Dates & Availability: When (and Where) Can You Get Them?

Google Pixel Watch 4 is on the cusp of release. Google has an event scheduled for August 20, 2025 (Made by Google) where the Pixel Watch 4 is expected to be officially announced alongside the Pixel 10 smartphone tomsguide.com tomsguide.com. If Google follows previous patterns, pre-orders might start immediately and the watch would ship in late August or early September 2025 tomsguide.com tomsguide.com. Leaks suggest both sizes (41mm & 45mm) will be available at launch in multiple colors (with different case colors for each size) androidauthority.com. Google often sells Pixel devices through its online store, carriers, and big retailers worldwide. Pixel Watches have so far been available in North America, Europe, and parts of Asia/Australia. By August 2025, you should be able to buy Pixel Watch 4 in all the same regions Pixel Watch 3 was sold, likely with initial supply in September 2025. Notably, there were rumors of a slight delay pushing it to October, but most sources point to late August launch being on track wareable.com. So as of now, expect to have Pixel Watch 4 on your wrist by early fall 2025 if you’re keen.

Samsung Galaxy Watch releases annually in late summer. The Galaxy Watch 7 was released on July 19, 2024, after being announced July 10 at Samsung’s summer Unpacked event braceletsmartwatch.fr braceletsmartwatch.fr. It became widely available through carriers, electronics stores, and Samsung’s site immediately thereafter. Fast forward to 2025: Samsung held another Unpacked on July 9, 2025, unveiling the Galaxy Watch 8 series (including a Watch 8 Classic and a refreshed Ultra) phonearena.com techradar.com. The Galaxy Watch 8 became available in late July 2025 (with some regions getting it in August). That means by August 2025, the latest Galaxy Watch (Watch 8) is hitting stores. However, the question focuses on Watch 6 and 7, presumably because those set the stage and Watch 7 is still a current model many might buy (especially if discounted after Watch 8’s intro). The Galaxy Watch 6 (2023) came out August 11, 2023 tomsguide.com and is of course still available (often at a lower price now). Samsung tends to keep selling the previous model for a while at a discount. The Galaxy Watch 7 (2024) is widely available and will likely continue to be sold through 2025 at possibly reduced prices or bundled deals as inventory lasts. The Watch 8 (2025) is the new kid on the block, with expanded features like the built-in AI. So, if you’re eyeing Samsung, you have multiple generations available as of August 2025: Watch 6 (cheaper), Watch 7 (balanced choice, refined features), and Watch 8 (latest and greatest). For most people, the Watch 7 and 8 series will be the focus. The Galaxy Watch Ultra (2024 model) released alongside Watch 7 and there’s an Ultra (2025) version launched with Watch 8 – these are available too for those wanting a bigger, more rugged watch. In terms of geographic availability, Samsung sells Galaxy Watches in all major markets (North America, Europe, Asia, etc.), often with both Bluetooth and LTE models available through carriers. One thing to check is compatibility: Samsung’s LTE watches usually come in regional variants for North America, Europe, etc., due to band support. If you’re buying an LTE model, make sure it’s the right variant for your carrier.

Apple Watch Series 10 was launched on September 9, 2024 at Apple’s fall event and released on September 20, 2024 apple.com. It’s been on the market since then and is widely available through Apple Stores, online, and carriers. By August 2025, the Series 10 is nearing its one-year mark and is “midway through its product cycle” macrumors.com. Apple typically launches the next model each September, so the Apple Watch Series 11 is expected in September 2025 alongside the iPhone 17 tomsguide.com tomsguide.com. That means Series 10 is still the current flagship Apple Watch for just a little longer. If someone is considering buying now (Aug 2025), they might weigh waiting a month for Series 11. According to MacRumors, Series 10 is still an excellent buy but “a new model is expected in September 2025”, so enthusiasts might hold off macrumors.com macrumors.com. Series 11 rumors aside (we’ll cover in a moment), the Series 10 remains available in Apple’s lineup likely until the Series 11 launch, at which point Series 10 might be discontinued or sold at a discount until stock clears. Apple also sells the Apple Watch SE (2nd gen) and Ultra 2 (2023) concurrently. Availability-wise, Apple Watches are sold in dozens of countries; LTE models have regional SKUs like Samsung’s. One difference: Apple Watch uses an eSIM that requires an iPhone and supported carrier plan; they’ve expanded support to many carriers worldwide. If you’re buying an Apple Watch in late 2025, you’ll have the choice of grabbing a discounted Series 10 or the new Series 11. For now, Series 10 can be purchased easily both new and in the used market. It launched at $399 and generally held that price – though by summer 2025 some retailers or carriers might offer small deals (e.g. $50 off or bundle offers, especially as Series 11 launch nears).

In summary: Pixel Watch 4 – officially launching August 2025, shipping by September. Galaxy Watch – latest Watch 8 just released July 2025, with Watch 7 (2024) still available (and likely on sale) as of Aug 2025. Apple Watch – Series 10 (2024) available now, but Series 11 right around the corner in Sept 2025. Buyers should consider whether to grab current models or wait for the next iteration, depending on each brand’s cycle.

Future Upgrades & Rumors: What’s Next for Pixel, Galaxy, and Apple Watch?

Each of these watches has a roadmap of exciting improvements on the horizon, as companies vie for smartwatch dominance with new features:

• Google Pixel Watch (Future): The Pixel Watch 4 itself is brand-new for 2025, but looking beyond, Google will likely continue annual releases. One area to watch (pun intended) is Google leveraging its AI prowess even more. The Pixel Watch 4 is already bringing Gemini AI assistant integration androidauthority.com androidauthority.com. We can expect future Pixel Watches (Pixel Watch 5 and beyond) to double down on AI – think advanced language translation on-watch, AI fitness coaching that analyzes all your data and gives you spoken advice, and maybe integration with Google’s AI cloud for complex tasks. Health-wise, Google’s acquisition of Fitbit means they’re likely working on advanced sensors too. There have been hints that Google is researching noninvasive glucose monitoring (a very challenging tech several big firms are chasing). No concrete timeline, but if any Wear OS watch were to get that in the coming years, Pixel Watch could be a candidate, leveraging Fitbit’s research (Fitbit had patents in that area). In the nearer term, Pixel Watch 5 (2026) might bring a fresh design or slimmer build – since Pixel Watch 4 kept a similar look, Google might iterate on style every few generations. Also, a popular request is longer battery life and more size options; Pixel 4 added a large size, so Pixel 5 could perhaps add an “Ultra” edition with an even bigger battery or more rugged build to compete with Apple’s Ultra and Samsung’s Ultra models. Google has also been expanding emergency features: an exciting expected feature is Satellite SOS. Code in Android has pointed to satellite connectivity for emergency texting; a report suggested Pixel Watch 4 (or 5) could gain the ability to send an SOS message via satellite if you’re off the grid tomsguide.com. That would mirror Apple’s Emergency SOS via Satellite (on iPhones) but in a watch – potentially life-saving for hikers. Another rumored feature is a built-in microLED display in a future Pixel Watch (microLED can be brighter and more efficient than OLED). MicroLED tech is still developing, but by late this decade we might see it in wearables. For now, Pixel Watch’s immediate future is all about that AI and polishing the experience to rival Apple Watch. Google is also improving the software with Wear OS 6, expected in 2025/26, which should bring smoother performance and more apps (already at Google I/O 2025 there were demos of Wear OS 6 on a Pixel Watch showing new features) androidcentral.com. In short, Google’s smartwatch vision is to make the Pixel Watch the ultimate Android companion with AI-driven smarts and Fitbit-powered health, and each generation should bring us closer to that vision.
• Samsung Galaxy Watch (Future): Samsung has been alternating strategies – in 2023 they had a Classic model with a physical bezel, in 2024 they dropped it in favor of an Ultra, and in 2025 they brought back a Classic alongside an updated Ultra. For 2025 and beyond, rumors suggest Samsung might continue offering multiple models: a standard, a Classic, and an Ultra, to target different user groups tomsguide.com tomsguide.com. The Galaxy Watch 8 (2025) introduced an interesting new feature: it’s the first Android watch with Google’s Gemini AI built-in tomsguide.com. This means Samsung watches will likely incorporate more on-device AI functions going forward – perhaps voice assistant that can summarize your notifications or intelligently suggest actions (e.g., detect you’ve finished a run and auto-suggest playing a cool-down playlist). Looking further, the Galaxy Watch 9 (if named so, in 2026) could push boundaries in health: Samsung has been reportedly working on noninvasive blood glucose monitoring using an optical sensor technique. They even showed research demos in the past. While it didn’t make it into Watch 7 or 8, the fact that Watch 7 was speculated to have it shows Samsung’s interest braceletsmartwatch.fr braceletsmartwatch.fr. If Samsung cracks that, a future Galaxy Watch could help diabetics measure blood sugar without a needle – a holy grail feature that would instantly make it a must-buy for millions. Samsung is also likely to improve their AI health coaching. The Watch 7 introduced AI “Wellness Tips” and analyses; expect the next-gen to expand this with something like personal voice coaching or more granular insights (perhaps similar to Fitbit’s direction, a daily readiness, etc., which Samsung now has as Energy Score). On hardware, Samsung might explore new form factors – there’s talk of a Galaxy “Ring” (smart ring) in development, which could complement the watch for health tracking. As for displays, Samsung is a display leader; we might see them adopt MicroLED displays in a couple of years on the watches, especially if Apple moves first (since Samsung often supplies or matches display tech). Another likely upgrade: the Exynos W series chips. The Watch 7 had Exynos W1000, Watch 8 possibly a minor bump or similar. By Watch 9 or 10, Samsung could launch a 5nm or 3nm chip with huge efficiency gains, leading to multi-day battery life – one of the biggest asks from users. Software-wise, Samsung will stick with Wear OS (which will be at Wear OS 5 or 6 by then) but will enhance One UI Watch. We might see more Google-Samsung collaboration on features (for example, deeper Assistant integration, or unique apps that leverage both Galaxy phone and watch together). Also, keep an eye out for new sensors: Samsung could add skin temperature tracking for cycle tracking like Apple (if they haven’t already via software), or even things like a UV sensor (Samsung had a UV sensor way back in 2014 on a Gear watch – could return for skin health awareness). Summing up, Samsung’s future watches will likely focus on health innovation (glucose, blood pressure), AI personalization, and refining the user experience, all while offering a variety (sport model, classic model, extreme model) to cover all bases.
• Apple Watch (Future): As we near the tenth anniversary of Apple Watch (which first launched in 2015), Apple is reportedly planning some major upgrades. The 2024 model was dubbed Series 10 (X) and brought a new design; for 2025, the Apple Watch Series 11 is expected to refine that. According to rumors, Series 11 will keep the same sizes and design as Series 10, focusing on internal upgrades tomsguide.com tomsguide.com. One big possible change is the display technology: Apple has been working on MicroLED displays for Apple Watch for years. Initially it was thought to come in 2025, but latest reports suggest it might be delayed to 2026 or appear first on an Ultra model tomsguide.com tomsguide.com. If not microLED, Series 11 might at least get a more efficient OLED (LTPO improvements) for better battery or higher resolution. The Series 11 is rumored to include a camera – Mark Gurman of Bloomberg says Apple is prototyping a tiny front-facing camera hidden in the top bezel or display tomsguide.com tomsguide.com. This would primarily be used for FaceTime (audio) or FaceTime Video (maybe just low-res selfies or Face ID in the future). However, Apple might also leverage a camera for their new Visual Lookup/Intelligence features on watchOS tomsguide.com tomsguide.com (imagine pointing your watch at a plant to identify it, etc.). Health features likely coming in Series 11 (or soon after) include the aforementioned blood pressure monitoring tomsguide.com tomsguide.com. Gurman and others have reported Apple is deep into developing a cuffless blood pressure feature that could alert wearers to hypertension by measuring pulse transit time. There’s an expectation that “all signs point to the forthcoming crop of Apple Watches debuting a blood pressure monitoring feature” tomsguide.com tomsguide.com. We might see that as soon as Series 11, which would be a headline addition. On the other hand, blood glucose on Apple Watch is still in the research phase – optimistic estimates put it 2-3 years away at least, possibly around 2027. Apple is known to be working on it (they reportedly have a secret team working on noninvasive optical glucose monitoring), but it won’t be in Series 11. Apple is also likely to upgrade to a new S12 chip for Series 11 tomsguide.com tomsguide.com. The S10 was more about efficiency; the S12 might boost performance or battery life. Interestingly, rumor has it Apple could add 5G connectivity to Apple Watch in the next couple of years tomsguide.com tomsguide.com. Current watches use 4G LTE, which is sufficient, but Apple might move to 5G for future-proofing – though that could impact battery unless they find a very efficient modem. There’s also talk of satellite messaging coming to Apple Watch (perhaps Ultra models first) tomsguide.com tomsguide.com. Given Apple introduced emergency satellite SOS on iPhone 14, extending a basic satellite SOS to Apple Watch Ultra would make sense for adventurers. In terms of design, after Series 10’s slimdown, Series 11 is expected to look the same externally tomsguide.com tomsguide.com. But further down the line, Apple might experiment with new materials or form factors – for example, a flexible display Apple Watch (there have been patents for wrap-around displays), or a more extreme rugged watch beyond Ultra. Also, Apple may finally change the band attachment mechanism in the future; a rumored magnetic band system was talked about for Series X but didn’t happen apple.com. For now, legacy bands remain compatible, but a new system could allow larger batteries or different designs. On the software side, watchOS 12 and 13 will likely incorporate more Apple Intelligence (AI) features. We might see a smarter Siri (Apple is working on a “Siri 2.0” with AI, though it’s delayed) tomsguide.com tomsguide.com, and more use of machine learning for features like Workout Coach (watchOS 12 is rumored to add an AI fitness coach) and daily health summaries. Apple could introduce a holistic health score too, similar to Fitbit or Garmin’s scores, to give users a quick gauge of overall wellness (there’s a hint of desire for a “daily energy score” from some experts) tomsguide.com tomsguide.com. In summary, the Apple Watch Series 11 in 2025 is expected to bring refined hardware, possible new health sensor (BP), and maybe a camera, while further out, Apple is aiming for breakthrough tech like glucose monitoring and microLED displays. And of course, September 2025 will also bring an Apple Watch Ultra 3, which according to leaks might get its own camera (side-mounted) and possibly satellite texting exclusive to it tomsguide.com tomsguide.com. The battle between Apple, Google, and Samsung will only heat up as they race to be the first with major new health capabilities.
