The Marathon General Purpose Quartz with Maraglo 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, as well as suit civilians' needs for a casual watch.

This updated version now features a sapphire crystal lens and still 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 Marathon GPQ also has a passive matte finish which aids in protecting infantry positions as this finish does not provide a reflective surface which would occur on a normal metal case. Fibershell is also an extremely lightweight material, an important factor on the battlefield where every ounce counts.

The back of the GPQ is made of 316L surgical stainless steel, a steel with low carbon content that will not corrode over time. The GPQ 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 GPQ guarantees you a high degree of accuracy in timekeeping.

The General Purpose Quartz uses non-tritium Maraglo luminous markings when, exposed to a light source will glow in the dark. This version is the Sage Green "US Government" markings edition and has no date window.
