The Marathon 34mm Sage Green GPM Standard-Issue Field Mechanical Tritium Type II (ref. WW194003SG-0106) is a modern military field watch rooted directly in the heritage of the original General Purpose watches issued to Allied forces during the 20th century. Built to MIL-PRF-46374G Type II Class 4 standards, the GPM keeps the formula intentionally simple: compact proportions, ultra-legible dial layout, lightweight construction, and dependable mechanical reliability. The matte black Type II dial paired with the distinctive sage green high-impact fibreshell case gives the watch a subtle tactical character that feels authentically military rather than fashion-driven.

Powered by the Seiko NH35 dual-wind mechanical movement, the GPM can be wound manually or automatically through its self-winding rotor, delivering approximately 41 hours of power reserve. The watch features self-illuminating tritium gas tubes on the hands and hour markers for constant low-light visibility, a sapphire crystal for scratch resistance, and a lightweight DEFSTAN nylon strap built for field use. Its compact 34mm case size stays true to historical military-watch proportions, making it exceptionally wearable while preserving the authentic feel of vintage-issued equipment.
