MWC 100atm / 3,280ft / 1000m Water Resistant Divers Watch in Stainless Steel Case with Helium Valve on Silicon Strap / 100% Swiss Made with Swiss 26 Jewel Automatic Movement

SKU: 100AT/SS/SIL/200 This 100% Swiss made divers watch is one of MWC's latest heavy-duty divers range and is extremely robust with a sapphire crystal, as well as being suitable for diving with mixed gases at extreme depths due to the 100ATM water resistance rating, the watch also has a wider strap at 24mm and a non-scratch ceramic bezel which is easier to grip in extreme cold. These watches are specifically designed for use by professional divers under very challenging conditions.  All MWC 100ATM models are fitted with a helium escape valve, people often ask us how helium gets into a dive watch in the first place and the answer is very simple, essentially a helium molecule is among the smallest of all molecules. What this means is because they are so small even though the seals are working fine to keep water out the helium molecules can still get through and enter the watch even though other gases and water cannot.The main users professionally of watches with helium escape valves are
