Edox CO-1 Bezel Lock Automatic

For decades, from the iconic Delfin of 1961 to the Hydro-Sub and the CO-1, family-owned Swiss watchmaker Edox has consistently pushed the boundaries of water-resistant watchmaking. Originally developed in 2006 for the demanding world of offshore powerboat racing, the CO-1 quickly established itself as a benchmark in robustness and reliability. Today, Edox expands this iconic line with the CO-1 Bezel Lock Automatic — a pure, purpose-built diver engineered to perform under extreme pressure.

Secured at all times

At the heart of the CO-1 Bezel Lock lies its defining feature: the bezel lock system. Designed to prevent any accidental movement of the diving bezel, it ensures absolute security when timing critical underwater phases. Combined with a scratch-resistant ceramic bezel and sapphire crystal, the system reinforces both functional reliability and long-term durability.

Mechanical precision

Powered by a Swiss automatic movement, the CO-1 Bezel Lock Automatic focuses on essential performance. Housed in a robust 42mm stainless-steel case, the movement drives hours, minutes, seconds and date with unwavering precision. The solid case-back underscores the watch’s tool-oriented character and its readiness for demanding conditions.

Engineered for the depths

Water-resistant to an impressive 300 meters, the CO-1 Bezel Lock Automatic is built to endure the most extreme environments. A screw-down crown, helium escape valve, and generous application of Super-LumiNova ensure reliability, safety, and legibility even in the darkest conditions. Every detail serves a clear purpose: to withstand pressure, control time, and remain dependable when it matters most.

The Edox CO-1 is the ultimate in dive watch engineering performance and design, also a master of the fantastic world beneath the waves. Water resistant up to 1000m / 100 ATM, protected by a scratch-resistant sapphire crystal and a ceramic bezel, the CO-1 is the perfect timekeeping tool for exploring the oceans.
