A date window sounds like a small addition until you rely on it every day. Reference WW194015BK-0008, the Marathon General Purpose Quartz with Date (GPQ-D), adds a date at 4:30 to Marathon's 34mm tritium field watch and pairs it with a U.S. Government dial and black DefStan strap.

Placing the date at 4:30 keeps the dial's 12- and 24-hour scales and bold numerals intact, so the watch reads just like the original GPQ while answering the question you ask most often after "what time is it?" The dial is marked "U.S. Government," with government markings on the caseback, and Marathon builds the watch to MIL-PRF-46374G, the military performance specification for general-purpose watches. Tritium tubes on the markers and hands glow continuously, day after day, for years.

The Swiss ETA F06.115 HeavyDrive quartz movement provides high torque and an end-of-life battery indicator. It sits inside a black composite fibreshell case, 34mm across and 11.5mm thick, light and low-glare. Sapphire crystal protects the dial, and the 11-inch black DefStan nylon strap offers extra length for larger wrists or cold-weather layers.
