For professional divers safety is the primary concern and we kept this in mind when constructing the 20’000 FEET by CX Swiss Military Watch™. The massive fold-out buckle with safety catch ensures the bracelet will not open unintentionally. The bezel – sporting a 60 minute graduation - rotates uni-directionally only and may be used even when wearing thick diving gloves. Crown and pushers are screw-down and the pushers indicate by a red marking when unscrewed. However, the water resistance is maintained down to 300 meters even with unscrewed pushers. The crown itself is protected by massive side-guards. The domed anti-reflective sapphire crystal is 10mm thick and can thus withstand a pressure of 750kg per cm2. Superluminova™ is used both on the hands and the indices to ensure perfect readability even in complete darkness. Even the small second hand uses Superluminova™ and thus allows the diver to ensure at any time that his timepiece is still working. The chronograph hands sport a distinctive red marking and can thus be clearly distinguished from the hour, minute and small second hands. The minute hand –the most important feature when diving – is distinguished by its special shape and size from the hour and the second hand. The 20’000 FEET by CX Swiss Military Watch™ is also fully anti-magnetic as per ISO norm 764.
