Pilot's Navigator 41mm with Date, Tritium, Sapphire Crystal, Steel Crown, Battery Hatch, ETA F06 Quartz Movement, Swiss Made, Military Issue

The Marathon Military Navigator Pilots Quartz is a highly accurate watch built to strict military specifications under MIL-PRF-46374G. Designed for pilots, parachutists, and law enforcement, this timepiece is made to withstand the challenges that may face it in a professional or everyday environment. Developed by Marathon Watch Company in 1986 as a request by Kelley Air Force Base for a watch that could be used at high altitude, withstand extreme changes in pressure and altitude, and be an easy-to-read timepiece for a pilot.

Powered by a Swiss-made, high-torque, 3-jewel ETA F06 quartz movement, the Military Navigator Pilots Quartz guarantees a high degree of accuracy in timekeeping, with an accuracy of -0.3/+0.5 seconds per day. It also includes an End of Life (EOL) indicator that will advance the seconds hand once every 4 seconds to inform the user when a battery change is needed.

The watch features a specialized fibershell case that is water-resistant to 6 atmospheres (60 meters - 200 feet), sweat and shock-resistant, as well as lightweight with a stainless steel engraved back and an easy-access battery hatch. Included with the watch is a 20-millimeter width nylon strap made under MIL-S-46383B, Type III, and a new 316L steel crown for improved functionality and durability.

Enhancing visibility in low-light situations, the Military Navigator Pilots Quartz uses self-contained Tritium gas tubes. 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 that contain an isotope of hydrogen, ensuring they will not dull down in brightness like normal photoluminescent (glow-in-the-dark) paint, which requires an external light source to create a glow.

The watch features a scratch-resistant sapphire crystal and a lightweight, high-impact fibershell case, making it durable and suitable for use in demanding environments. It is also built to government specifications for use by military personnel, as evidenced by the Nato Stock Number 6645-01-544-9475 engraved on the case back.

In summary, the Marathon Military Navigator Pilots Quartz is a reliable and rugged timepiece designed for pilots, parachutists, and law enforcement professionals. Its Swiss-made movement, self-illuminating Tritium gas tubes, and military-grade construction ensure it can withstand the rigors of a professional or everyday environment, making it a dependable companion for those who demand the highest level of performance from their equipment.
