MIL-PRF-46374G is the U.S. military performance specification for general-purpose wristwatches, and the Marathon SSGPM in reference WW194003SS-0008 is built to that lineage with a dial that reads "U.S. Government." It is a 36mm steel, hand-wound field watch for buyers who care about issue authenticity.

The government marking is not decoration. On Marathon watches it appears at the top of the dial and is mirrored by government markings on the caseback, identifying the configuration made for official supply. Marathon's watches are issued to and used by members of the U.S. and Canadian militaries and other agencies, and the company's military work goes back to a 1941 Royal Canadian Air Force order. That record is what gives a U.S. Government dial from Marathon its credibility.

The case is 316L stainless steel with a Parkerized matte grey finish, 11mm thick and 44mm lug to lug. Inside, a Swiss Sellita SW210-1 hand-wound movement with 18 jewels runs for about 45 hours per winding. Tritium tubes light the markers and hands, sapphire protects the dial, and 5 ATM water resistance handles weather. This version is fitted with a black DefStan nylon strap in 11-inch length, long enough for a jacket sleeve.
