General Purpose Quartz w/ Date & Tritium (GPQ)
The Marathon General Purpose Quartz with Data and Tritium is a highly accurate watch built to strict military standards under MIL-PRF-46374G, Type I, Class 1. Designed for field use by infantry or other military personnel, the General Purpose Quartz is built to withstand the needs of infantry, as well as civilians looking for a perfect casual watch.
Developed by Marathon Watch Company as a field watch to be issued to military personnel, the General Purpose Quartz is a watch that meets all the requirements of a true military field watch. Made from a highly durable, impact resistant fibershell case that is water resistant to 3 atmospheres (30 meters – 100 feet), sweat resistant and will not yield to the elements.
The fibershell case of the General Purpose Quartz with Data and Tritium is also a passive matte finish, as to not give away infantry position through reflections which would occur on a normal metal case. Fibershell also is an extremely lightweight material, an important factor on the battlefield where every ounce counts. The General Purpose Quartz uses a special Hesalite crystal which is durable against impacts and will not shatter if dropped. The back of the General Purpose Quartz is made of 316L surgical stainless steel, a steel with low carbon content that will not corrode over time.
The General Purpose Quartz with Data and Tritium is made in La Chaux de Fonds Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Powered by a Swiss made, high torque, 3 jewel ETA F06 Quartz movement, the General Purpose Quartz guarantees you a high degree of accuracy in timekeeping. The ETA F06 is accurate to -0.3/+0.5 seconds per day and also includes an End of Life (EOL) indicator that will advance the seconds hand once every 4 seconds to inform you that a battery change is needed. The General Purpose Quartz 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 photoluminescent paint which requires an external light source to create a glow.
The General Purpose Quartz combines military durability with Swiss craftsmanship to provide an accurate timepiece that will satisfy you for years of daily use.
