MARATHON 34mm Black General Purpose Mechanic (GPM) WW194003BK-0101

Light, Functional, and Uncompromising

The General Purpose Mechanical – GPM for short – is a modern duty watch with military DNA, manufactured according to the strict requirements of MIL-PRF-46374G, Type II, Class 4. This standard ensures that the watch functions reliably in extreme situations as well as in everyday life. Originally developed for the US military, the GPM remains a symbol of robust, practical watchmaking to this day.

Compactly Built for Maximum Performance

With a case diameter of 34 mm, the GPM offers a comfortable fit that is neither bulky nor obstructive. The casing is made of a high-strength composite fiber shell, ensuring exceptional durability with low weight. Ideal for individuals who want to barely feel their equipment – but must rely on it at all times.

Automatic Movement with Manual Winding Option

Inside, the proven Seiko NH35A automatic movement operates, which can be wound both by a self-winding rotor and manually via the crown. This dual power supply makes the watch particularly reliable, whether in civilian life or under difficult conditions. With 24 synthetic jewels, the movement ensures smooth operation and reduces friction to a minimum.

Military Functionality – Clearly Structured

The dial features a dual scale with 12-hour and 24-hour display, making it equally easy to read standard time and military time. A date display is intentionally not integrated into this model to keep readability clear and direct – in the spirit of a true field watch.

Visible at All Times – Even at Night

Tritium gas tubes on the hour markers and hands ensure excellent readability in complete darkness. Unlike conventional luminous paint, tritium is self-luminous and does not require an external light source for charging. This ensures the watch remains constantly readable day and night, for many years.

Resistant in Every Aspect

A scratch-resistant sapphire crystal protects the dial from impacts and wear. The watch is also water-resistant up to 3 ATM, making it splash and rain proof – perfect for daily use under realistic conditions. The push-pull crown contributes to the simple, functional appearance without sacrificing technical integrity.
