MWC 500m (1640ft) Water Resistant Stainless Steel Automatic Divers Watch With Sapphire Crystal, Ceramic Bezel and Helium Valve

SKU Code: XLDAU12/SS/500

The MWC Kampfschwimmer (Military Diver) 500B m water-resistant models with helium escape valve are one of MWC’s latest heavy-duty range of divers watches and have a significantly more robust case than most other military dive watches, they also have additional crown protection, inB addition, this model also has the advantage of an impact-resistant sapphire crystal and a scratch-resistant ceramic bezel.

The Kampfschwimmer range also uses a wider strap at 24B mm (most military divers watches use a 20mm strap) and a thicker bezel design. The thicker bezel makes it significantly easier to grip which is a feature which was specified in a procurement contract because these watches were specifically designed for use by Police and Military divers as well as for use in inflatables operating in cold and extreme environments.

This particular model has a European NATO pattern dial and is finished in brushed stainless steel. The movement is a high quality 24 jewel automatic with hacking function to enable synchronisation. The movement also has a 41-hour power reserve.

* 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 stressesb which can cause weaknessb 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.
