MWC P656 2023 Model PVD Titanium Tactical Series Watch with GTLS Tritium and Ten Year Battery Life (Date Version)
SKU Code: TP656D/A1/LI/L22
The robust 300m water-resistant MWC Tactical Series of watches in Titanium cases were specifically designed for law enforcement, marine, surface and airborne applications, they are manufactured to surpass U.S W-46374F Type 6 specifications, these watches are regularly ordered by a bulk contract client who places substantial orders each year for variants of this specific design, the watches 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 and bezel (the first watch of this pattern in the 1990s was the P650 which was made from Polyamide), the shatter-resistant sapphire crystal, water resistance is also significantly increased by a factor of 10 from 30m to 300m (99ft to 1000ft) and there is also the addition of a screw-down locking crown and caseback. 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 calibre 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/300m) 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 12,000m / 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.

* A lot of people ask us what are the benefits of sapphire crystal over a standard mineral crystal? The answer is that synthetic sapphire is by far the best material for watch crystals because it is very strong and also shatter and scratch-resistant, these characteristics make it very appealing to military and security personnel, police officers and people who lead active outdoor lifestyles, these groups account for over 70% of our customers. To get things into perspective we find that when clients have accidents with watches resulting in a cracked crystal over 90% usually watches with mineral glass crystals, even factoring in that we use hardened mineral crystals they still do not come close to sapphire for durability under adverse conditions. The reason that sapphire crystals are so strong is that after the sapphire glass is manufactured it is also heat-treated to remove its internal stresses—which can cause weakness—it is then made into the watch crystals and two layers of anti-reflective coating are applied, interestingly sapphire crystal is now used on the latest iPhone. Of course, sapphire crystal comes at a price hence you find that it's normally only fitted to higher-end watches.
