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.

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.
