CO-1 Date Automatic

The CO-1 Date Automatic, reference 80137-37GNO-AO, is a diver's watch from Edox's CO-1 collection, 42 mm across and 14 mm thick in stainless steel with grey PVD, water resistant to 300 metres. It has a silver dial and comes on a rubber strap. Inside is an automatic movement Edox calls the Caliber 80, naming the Sellita SW 200 alongside it. The helium valve matters to saturation divers: helium that seeps into the case during long stays at depth can escape through it on the way up, instead of pushing the crystal out. The rotating ceramic bezel times a dive: set its zero against the minute hand and the elapsed minutes read straight off the scale, and the bezel lock stops it being knocked out of place. Edox gives its weight as 140 g.
