Some mornings there is no time to wind a watch or reset a stopped one. Reference WW194015SS-0108, the Marathon SSGPQ-D on a black DefStan strap, is built for exactly those days: a 36mm stainless steel Swiss quartz field watch with date that is always running, always accurate and always lit.

Quartz is the obvious choice for a true grab-and-go watch, and the Swiss ETA F06.115 HeavyDrive is a robust one, delivering high torque to the hands and an end-of-life indicator that warns when the battery is low. The steel case, 316L stainless at 36mm and 11mm thick, gives this Officer's model more substance than the composite GPQ-D and boosts water resistance to 5 ATM. The black dial is free of government markings, with tritium tubes that glow constantly, 12- and 24-hour scales and a handy date.

Built in the tradition of Marathon's MIL-PRF-46374G field watches, it is protected by sapphire crystal and set via a pressure crown. The black DefStan nylon strap, 11 inches long, is a British military pattern that keeps the watch secure and allows room for a sleeve or larger wrist.
