The watch is water resistant to 6 ATM (196 Ft) but is not a diving watch so continuous water immersion is not recommended. It is designed for maintaining accuracy at high altitude to 35,000 FT without compensating pressurization. This is the authentic 1st quality military item and not the commercial, military style "Navy Seals" watch available to the general public marketed by Luminox nor the watches manufactured by MB-Microtec (Mil-W-46374F copies).The watch measures 42x46mm (not including the crown) with a 20mm lug width (strap size). This watch is powered by a NEW Eveready. 371 watch battery and is accurate to +/- 21 seconds per month mine is actually right on after many weeks! By pulling the crown out, the second hand is stopped (hacked) for synchronization. 12 O'clock illuminated in red. Easy to read at night.
Watch is manufactured to MIL-46374G specifications. Stainless steel back is laser engraved. This is a great looking timepiece that is the actual military issue and has met rigorous military specifications. It is not a factory second or government rejected watch.The case is made of an extremely durable tan nylon/fiberglass composite material. The rotating outer bezel provides marking for a second-time-zone. The crystal is an aircraft quality lightweight Lexan material allowing for strength and scratch removal. The dial features the radioactive symbol (Tritium isotope).
Tritium is a radioactive isotope of hydrogen. When it decays, it emits beta particles (electrons) that do not penetrate the skin, plastic, glass, etc. The electrons excite the coating on the vials, creating a bright green glow. It is a safe (but very expensive) method of illumination and is used mainly in military watches and gun sights. This is brand new and comes complete with military sage green nylon flight strap (watch can be worn on the wrist or over one's flight jacket) and original box & instructions!
