The General Purpose Field Series

Marathon General Purpose (GP) watches harken back to the original field watches developed by Marathon and issued to Allied forces in 1941. Built to U.S Military Standard MIL-PRF-46374 G with direct lineage to the legendary GG-W-113 Spec of the 1960s. These straightforward timepieces are designed for officers and infantry, purposefully engineered to handle the demands of ground operations.
Available in both 316L stainless steel and high-impact composite fibreshell for ultra-light durability, these watches offer hand-wind, mechanical and quartz iterations, full nighttime visibility, and an overall uncomplicated build.
