The 20’000 FEET by CX Swiss Military Watch™ reaches into a new, hitherto unthinkable dimension of water resistance and is the world’s first and only serial mechanical diving watch water resistant to an incredible 20’000 feet or 6’000 meters – certified by the GUINNESS BOOK OF WORLD RECORDS as the world record holder since 2009! But not enough – in order to comply with ISO norm 6425 we constructed the watch to be water resistant to 7’500 meters, resulting in the required 25% safety margin and annihilating Rolex’ world record of 2008 by an impressive 50%.


A timepiece like no other, a technological breakthrough setting a new benchmark. The domed anti-reflective sapphire crystal is a solid 10mm thick and can withstand a pressure of 750kg - per square centimeter. The 20'000 FEET is limited to 1'000 pieces only and comes in a heavy-duty wooden gift box including a rubber strap. A tool for professional divers indeed!
