Edox CO-1 Titanium Chronograph

For decades, from its legendary Delfin in 1961 to the Hydro-Sub and now CO-1, boutique Swiss watchmaker Edox has been constantly raising the bar for water-resistant watches. The primary Edox CO-1 timepiece was engineered in 2006 for offshore powerboat racing, a bold fusion of water- resistance, sturdiness and beauty.

Tough and durable, the new CO-1 Titanium Chronograph is probably the world’s best swiss made chronograph up to € 2’000 and here are the reasons why: Forged from tough but lightweight titanium, the CO-1 is rated to withstand water pressure down to a crushing 1000m. Absolute accuracy while underwater is assured thanks to the special double o-ring patented Edox gasket for the crown and pushers.

A 4mm-thick scratch-resistant sapphire crystal protects a dial packed with functionality, including chronograph sub-dials and date window. A ceramic, scratch-resistant unidirectional bezel allows divers to mark off their dive times. To ensure readability at such depth, the hands and indexes are covered with a high standard of night visibility in the watchmaking industry – Super-LumiNova X1. Before being released, every CO-1 is subject to Edox’s meticulous quality controls in real water.

The ultimate timekeeping companion, CO-1 is a beautiful example of Edox’s commitment to the Swiss watchmaking craft, from hand-assembling to technical innovation and clean, functional design. Whether you are deep under the ocean or in a business meeting, the new CO-1 Titanium Chronograph is the perfect timekeeping tool.

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.
