CX Swiss Military Watch™ 12’000 Feet

With an incredible 3657 meters water resistance, CX SWISS MILITARY’s 12’000 Feet combines state-of-the-art technology with a highly innovative approach.

The Oceanographic Institute of the University of Southampton has successfully tested and certified the water resistance both in a pressure tank and in the Atlantic Ocean, exposed during a whole year to a pressure of 250 ATM. Not a surprise that this instrument for professional divers, limited to 365 pieces, entered the Guinness Book of World Records.

CX Swiss Military Watch™ 12'000 Feet

While the CX Swiss Military Watch’s 12000 FEET is undeniably exceptional in size and weight it is also easy and comfortable to wear with the rubber strap.

The 12000 FEET comes with a massive solid stainless steel bracelet. This bracelet alone is as heavy as most ordinary watches, yet comfortable to wear as its weight counterbalances the weight of the case.

The engraved butterfly-buckle is secured by a safety-clasp and operated by two pushers; it also has a diver’s extension. This extension and the screwed links allow for easy adjustment of the length of the bracelet. The quality of the bracelet seems to fall somewhat below the quality of the case.

Charmex offers the following choice of dials: yellow, black blue and silver. The yellow version obviously offers more contrast than the black or blue and is, together with the red and white logo, more active. The black edging of the hands somewhat reduces their readability on the black dial though.

The crown offers a fantastic grip (no wonder with a  diameter of 8mm) and an engraving aligned with the case; the pushers have  markings “unlocked” / “locked”; the caseback is stylishly engraved (with an  embedded colour marking); the perfect fitting of the sapphire crystal.
