Designed in Canada and manufactured in Switzerland, Marathon watches are designed to meet some of the toughest MIL SPEC standards out there. The GPM (General Purpose Mechanical) watch is made for infantry units to withstand anything they may encounter in the field. The standard that defined the specs of the General Purpose Mechanical watch was born out of military necessity, but it’s just as useful as a civilian. The GPM is an all-purpose watch with a reliable Japanese automatic movement, housed in a lightweight and high-impact composite case and some tough military vibes that’ll be right at home in your collection.

Measuring in at 34mm wide by 11mm thick, the composite case is light on the wrist. It stays strapped on thanks to the thin 16mm nylon strap that coordinates with the case color. The dial is what you’d expect from a field watch — clean and legible with a 12- and 24-hour scale. Bold white hands really pop out from the matte black dial. To take legibility to the next level, the hour and minute hands / hour markers on the dial are adorned with tritium gas tubes that constantly glow in the dark without needing exposure to light like standard lume would. The dial is protected by a scratch-resistant sapphire crystal for extra durability. 

Inside the GPM, you’ll find Seiko’s NH35 - a reliable Japanese-made “Dual Winding Movement” that can be wound both manually via the crown, or automatically via the internal rotor. It’s good for 41 hours of power between windings and features a beat rate of 21,600bph for a smooth seconds sweep. 24 jewels inside the movement keep everything running smoothly.
