Strap it on, check the time, and get moving. The Marathon General Purpose Quartz (GPQ), reference WW194004BK-0801, is the grab-and-go version of Marathon's 34mm field watch: Swiss quartz accuracy, tritium that never needs charging and a sterile black dial with nothing to distract from the time.

The heart of the GPQ is the Swiss ETA F06.115 HeavyDrive, a high-torque quartz movement designed to drive larger hands reliably. It includes an end-of-life indicator that warns you when the battery is running low, so you are never caught out by a dead watch. There is no winding and no setting after a weekend off; it is simply ready. Tritium gas tubes on the markers and hands glow continuously for years, and the sterile dial carries no government or unit insignia, only clean numerals and 12- and 24-hour scales.

The case is black composite fibreshell, 34mm across and 11.5mm thick, light enough to wear while sleeping, working out or traveling. Marathon builds the GPQ to MIL-PRF-46374G, Type I, Class 1, with sapphire crystal over the dial and a black one-piece nylon strap that is quick to put on and dries fast.
