This particular model is no longer in production with MWC so is now quite rare and sought after.

We buy these watches from various defence auctions and other disposal sales and this model is very close to the original MIL-W-4374F-TYPE 6 from 1995  although of a much higher specification. The original MIL-W-4374F-TYPE 6 can be seen in the last image.

Model: P656ND/1

SKU Code: P656ND/1

The robust 300m water-resistant MWC Tactical Series 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 significant upgrades bringing them up to modern specifications, an example of one of the original 1990’s watches appears in the final image, as far as the upgrades are concerned the main improvements are the solid steel case - the 1990s watches were carbon fiber, water-resistance being increased by a factor of 10 from 30m to 300m (165ft to 1000ft), plus the screw-down crown. 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 715li Movement. The watch is water-resistant to 30 ATM (1000 ft/300m) although it is not a dedicated diving watch it is ideal for all activities on land or in water and is manufactured to the same water resistance rating as MWC's dedicated diver's models with a screw-down crown and caseback.

The main difference between this watch and many other models which MWC manufacture is that it is designed to maintain high levels of accuracy at altitudes up to 12,000m / 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.
