A field watch does not have to stay in the field. Reference WW194003SS-0108, the Marathon SSGPM with no government markings, is a 36mm steel hand-wound watch whose clean black dial and slim 11mm profile make it as comfortable at a desk as it is on a hike.

With only the MARATHON name on the dial, this configuration of the Steel General Purpose Mechanical keeps things minimal: bold numerals, 12- and 24-hour scales and tritium-lit hands and markers that stay visible in a dim conference room or a dark parking lot. The Parkerized 316L stainless case has a soft matte grey finish that is subtle enough for business casual and tough enough for weekends. Its 36mm diameter and 44mm lug-to-lug length fit a wide range of wrists without looking oversized.

Underneath, a Swiss Sellita SW210-1 hand-wound movement with 18 jewels delivers around 45 hours of reserve, which means one wind per day keeps it running. Marathon fits sapphire crystal and rates the case to 5 ATM. This listing is finished on a black DefStan nylon strap measuring 11 inches, a sturdy choice that can be swapped out easily when the mood changes.
