The Marathon General Purpose Quartz is a highly accurate watch built to strict military standards (MIL-PRF-46374G, Type II, 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.
The General Purpose Quartz is 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 also has a passive matte finish. This matte finish 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.
