Marathon 34mm Black GPM Standard-Issue Field Mechanical Tritium Type II WW194003BK-0108
The Marathon 34mm Black GPM Standard-Issue Field Mechanical Tritium Type II (ref. WW194003BK-0108) is one of the purest modern military field watches still built to actual government specifications. Known as the General Purpose Mechanical (GPM), this watch traces its lineage directly back to the field watches issued to Allied forces and later GG-W-113 military watches used throughout the Cold War era. Designed around simplicity, durability, and legibility, the GPM features a compact 34mm high-impact composite fibreshell case, matte black Type II dial, and fixed bezel that prioritize function over luxury styling. Manufactured to MIL-PRF-46374G Type II Class 4 standards, it feels less like a modern collector piece and more like genuine issued equipment.
Powered by a Seiko NH35 dual-winding mechanical movement, the GPM can be wound manually or through its automatic rotor, giving it modern reliability while retaining the tactile feel of a traditional field watch. It features self-illuminating tritium gas tubes on the hands and hour markers for constant low-light visibility, a sapphire crystal for durability, and a lightweight nylon DEFSTAN military strap that reinforces its utilitarian character. Unlike oversized modern field watches, the 34mm sizing stays true to historical military proportions, making it exceptionally wearable and authentically vintage in feel without sacrificing contemporary toughness.
