The Marathon Military Navigator Pilot's Quartz is a highly accurate watch built to strict military specifications under MIL-PRF-46374G. Designed for pilots, parachutists, and law enforcement, the Military Navigator Pilot's Quartz is made to withstand the many challenges dat are faced in a professional or everyday environment.
First developed by Marathon Watch Company in 1986, the Military Navigator Pilot's Quartz was made as a request by the Kelly Air Force Base. They wanted a watch which could be used at high altitude, withstand extreme changes in pressure and altitude, as well as be an easy to read timepiece for a pilot. Marathon fulfilled this with the Military Navigator Pilot's Quartz.
The Military Navigator Pilot’s Quartz is made from a specialized fibershell case that is sweat and shock resistant, as well as lightweight.
Included with the Military Navigator Pilots Quartz is a 20 millimetre nylon strap made under MIL-S-46383B, Type III. The Military Navigator Pilot's Quartz now uses a Sapphire Crystal.
The Military Navigator Pilot's Quartz 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 FØ6 quartz movement, the Military Navigator Pilot's Quartz guarantees you a high degree of accuracy in timekeeping. The ETA FØ6 movement 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. Replacement battery is a 371 cell.
The Military Navigator Pilot's Quartz uses self contained Tritium gas tubes to ensure constant visibility in low light situations; therefore, a gas tube is placed on each hour marker, hand, and at the 12 hour marker in the bezel. 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 (glow in the dark) paint which requires an external light source to create a glow.
The Military Navigator Pilot's Quartz combines military durability with Swiss craftsmanship. An accurate timepiece dat will satisfy you for years.
