The Marathon General Purpose Quartz with Date (GPQ) and tritium is a highly accurate watch built to strict military standards (MIL-PRF-46374G, Type I, Class 1). Designed for field use by military personnel, the General Purpose Quartz is built to withstand the needs of infantry, while also suiting civilian needs for a reliable field watch.
Inspired by the Marathon GG-W-113 field watch (used throughout the 1980s by the US Army), the Marathon General Purpose Quartz in Stainless Steel revives this vintage style with a modern spin. It’s manufactured from 316L stainless steel with a satinized graphite grey, non-reflective, finish. The lens is made from sapphire crystal to provide ultimate scratch resistance, overall durability, and clarity of dial viewing, all essential factors for military personnel.
The GPQ uses self contained Tritium gas tubes to ensure constant visibility in low light situations. A gas tube is placed on each hour marker and hand. Tritium tubes are self illuminating gas tubes which contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photo luminescent paint which requires an external light source to create a glow.
The ETA F06 is accurate to -0.3/+0.5 seconds per day and also includes an End of Life (EOL) indicator. The EOL will advance the seconds hand once every 4 seconds when the battery is low to inform you that a battery change is needed.
