Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126515LN-0004 is a 40 mm chronograph in Everose gold. The case measures 11.9 mm thick and carries a black monobloc Cerachrom bezel with a tachymetric scale, set beneath a scratch-resistant sapphire crystal. The bright black and Sundust dial is set with diamonds and shows luminous hands and indices alongside a small seconds subdial. Inside is the calibre 4131, a self-winding Perpetual movement with a chronograph function, chronometer-certified and offering 72 hours of power reserve. The watch rides on an Oysterflex bracelet, combining flexible metal blades with an elastomer overmould, secured by a folding Oysterlock safety clasp in rose gold with the Glidelock extension system. The Triplock screw-down crown helps keep the case waterproof to 100 metres.
