Up for sale or trade is a world record holder for an automatic COSC chronograph Swiss Miliatry Carmex 20,000 feet chrono. In near mint condition and operating as it should this chronograph is not for the meek or shy about wearing this beast.
Comes as a complete set with inner and outer box(measures 13x10in) all documentation see photos. The watch comes with 2 screw drivers though in the original packaging it only came with one. From their website the following information:
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 box including a rubber strap. A tool for professional divers indeed!
