MWC 300m Water Resistant Stainless Steel Navigator Watch with Luminova - Not Running but New
This watch is a NAV/QZ/ST/LU below is a full description of this particular watch and the issues which it has (or is reported to have because in many cases the watches do not have significant issues, below that is the full information relating to this model from the factory website which gives full details of all of the dimensions, specification and other information relating to the watch.
We buy these watches from various defence auctions and other disposal sales and it's frequently the case that we find that there is actually nothing wrong with the watch but it has to be assumed it will have some form of fault though in most cases it's very minor or as described below. These watches are disposed of at low-cost because we find that one of the problems is pressure of time for our service staff in the UK and elsewhere and in most cases they have given them a quick check over and nothing is immediately apparent though we have to assume that there is either no real fault with the watch or something will reveal itself over time in which case it’s normally a simple case of a service, repair or battery exchange depending on the exact model
Condition: Looks New
Fault: Nothing apparent looks 100% new but not running, maybe a battery needed or worst case a new Ronda 715li movement.
These robust 300m water resistant watches were specifically designed for marine, surface and airborne navigation applications, manufactured to U.S MIL-PRF-46374G specification. The watches all have a 12hr bezel, which offers a very simple and straightforward method to track a second time-zone. The bezel has high visibility numerals and the dial is also very clear and easy to read even under adverse light conditions.
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 diving watch due to using an entirely different bezel format to permit usage in two time zones it is manufactured to the same water resistance rating as our diver's models with screw-down crown and caseback. 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 case is made of stainless steel. The rotating outer bezel provides annotations to enable the watch to show the time in two different time zones.
The crystal is military-grade sapphire which is highly scratch resistant with two internal layers of non-reflective coating. 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.
