Description
Designed for elite offshore racers and professional deep-sea divers, the Edox CO-1 Bezel Lock Chronograph (01128-3NOCA-BUIDN) represents the absolute pinnacle of Swiss high-performance horology and mechanical ingenuity.
Innovative Bezel Lock Technology
Safety and precision are paramount in professional diving. This timepiece is equipped with Edox’s proprietary Bezel Lock system, a sophisticated mechanism that locks the rotating ceramic bezel securely in place, completely eliminating the risk of accidental rotation and incorrect elapsed-time tracking underwater.
Extreme 500M Dive Engineering
Engineered to withstand the crushing pressures of the deep ocean, the CO-1 features a massive 45mm stainless steel case, screw-down pushers, a screw-down crown, and an integrated automatic helium escape valve for safe decompression. With an incredible 500-meter (50 ATM) water resistance, it is a true instrument of the abyss.
High-Performance Swiss Chronograph
Driven by the robust Edox Caliber 011 automatic chronograph movement, it delivers split-second stopwatch precision alongside practical day and date sub-dials. The vibrant blue dial is framed by a scratch-resistant sapphire crystal, offering unmatched legibility, durability, and bold masculine elegance.
