The line between Marathon's 1941 field watches and reference WW194015SG-0006 is remarkably direct. This sage green GPQ-D, with a U.S. Government dial and matching DefStan strap, is a 34mm Swiss quartz watch that keeps the essential layout soldiers relied on and adds a date, tritium and sapphire.

When Marathon received its first military order in 1941, field watches were simple tools: legible dials, compact cases and dependable movements. The specifications that followed, from GG-W-113 in the 1960s to today's MIL-PRF-46374G, formalized that formula, and the General Purpose Quartz with Date is built to the modern standard. Its black dial carries "U.S. Government" at the top, with government markings on the caseback, plus 12- and 24-hour scales and a date at 4:30.

Modern upgrades are where it pulls ahead of its ancestors. Tritium tubes glow on their own for years, a sapphire crystal resists scratches, and the Swiss ETA F06.115 HeavyDrive quartz delivers high torque with an end-of-life battery indicator. The sage green fibreshell composite case is light and 11.5mm thick, and the sage DefStan nylon strap gives a coordinated, kit-ready finish.
