Alpina AlpinerX Pro

Citizen Promaster Tough uses a one-piece monocoque case with Duratect hardening, making the case five times harder than standard steel, and is offered with a 5-year warranty. The 2023 Ray Mears edition in Super Titanium (BN0118/BN0241) measures 41mm x ~12mm and weighs about 50g. The Promaster Tough runs on Citizen Eco-Drive Caliber E168, a solar quartz movement that yields up to six months of run time in darkness on a full charge. It is rated to 200m water resistance with a screw-down crown and sapphire crystal, and it has no smart sensors or digital displays. AlpinerX Pro GPS Alive uses
