Dependability is the point of a military watch, and the Marathon GPQ, reference WW194004SG-0906, is designed around it. This 34mm sage green field watch with a U.S. Government dial runs on a high-torque Swiss quartz movement that even warns you before its battery gives out.

The Swiss ETA F06.115 HeavyDrive is engineered to move larger hands with authority, and its end-of-life indicator signals when the battery is running low, a simple feature that matters when a watch is relied on for timing. Combine that with tritium gas tubes that glow continuously for up to roughly 20 years, and you have a watch that needs almost nothing from its owner. Sapphire crystal resists scratches, and the sage green fibreshell composite case is light and tough.

The black dial reads "U.S. Government," with government markings on the caseback, and includes 12- and 24-hour scales. Marathon builds the GPQ to MIL-PRF-46374G, Type I, Class 1. This configuration comes on an 11-inch sage green DefStan nylon strap that matches the case and allows wearing over a sleeve.
