The Marathon Navigator Pilot's Quartz is a highly accurate watch built to strict specifications under MIL-PRF-46374G. Designed for pilots, parachutists, and law , the Navigator Pilot's Quartz is made to withstand the many challenges that are faced in a professional or everyday environment. First developed by Marathon Watch Company in 1986, the 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 Navigator Pilot's Quartz. The Navigator Pilot’s Quartz is made from a specialized fibershell case that is sweat and shock resistant, as well as lightweight. Included with the Navigator Pilots Quartz is a 20 millimetre nylon strap made under MIL-S-46383B, Type III. The Navigator Pilot's Quartz now uses a Sapphire Crystal. The 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 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 Navigator Pilot's Quartz uses self contained Tritium tubes to ensure constant visibility in low light situations; therefore, a tube is placed on each hour marker, hand, and at the 12 hour marker in the bezel. Tritium tubes are self illuminating tubes which contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photo-luminescent (glow in the
