FACTORY SPECIFICATION

SKU Code: P656D/D1/LI

The robust 300 m water-resistant MWC Tactical Series of watches were specifically designed for marine, surface and airborne applications, they are manufactured to surpass U.S. W-46374F Type 6 specifications, these watches were ordered by a bulk contract client and are based on designs made in the mid-1990s but with multiple upgrades, one of the original watches appears in the final image, the main improvements are the solid titanium case (the first watch of this pattern in the 1990s was the P650 which was made from Polyamide), water resistance is increased by a factor of 10 from 30 m to 300 m (99ft to 1000ft) and the addition of a screw-down crown and heavy-duty screw caseback etc significantly upgrades the specification. The bezel has high visibility numerals and the dial is also very clear and easy to read even under adverse light conditions. The watch uses Swiss Tritium GTLS (Gaseous Tritium Light Sources) which are significantly brighter than any conventional luminous watch.

The timepiece features a high-quality Ronda high precision Quartz Movement (Ronda caliber 715li) designed to withstand high G-forces which has an incredible 10-year battery life as well as an end of battery life indicator. The watch is water-resistant to 30 ATM (1000 ft/300 m) although it is not a dedicated diving watch it is manufactured to the same water resistance rating as our diver's models with a screw-down crown and caseback and is suitable for all land-based or marine requirements.

The main difference between this watch and many other models which we manufacture is that it is designed to maintain high levels of accuracy at altitudes up to 12,000 m / 40,000ft without compensatory pressurization.

The dial features a radioactive tritium symbol. Tritium is a radioactive isotope of hydrogen. When it decays, it emits beta particles, although these do not penetrate the skin, plastic, glass, etc. Whilst the vials contain radioactive gas even when they are all taken together they contain less than the personal limit of 25 millicuries - see U.S Nuclear Regulatory Commission regulations 10 CFR 30.15.
