The DT in reference WW194004DT-0803 stands for desert tan, and it changes the personality of Marathon's General Purpose Quartz entirely. This 34mm tritium field watch wears a sand-colored composite case and a sterile black dial, a combination that looks purposeful without looking aggressive.

Desert tan has been a staple of military equipment for good reason: it blends into dry terrain and complements almost any outdoor clothing. On the GPQ, the tan fibreshell case frames a black dial that carries no government markings or insignia, just clear numerals, 12- and 24-hour scales and tritium tubes on the hands and markers. Those tubes glow steadily for years, no sunlight needed, so the watch is readable from dusk to dawn.

Inside, the Swiss ETA F06.115 HeavyDrive quartz movement provides high torque for the hands and an end-of-life indicator to warn of a low battery. Marathon builds the GPQ to MIL-PRF-46374G, Type I, Class 1, with sapphire crystal, a pressure crown and an 11.5mm case height. A one-piece nylon strap keeps the setup light and simple. It is an easy watch to live with, from errands to campsites.
