Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126515LN-0002 is a chronograph in 18 ct Everose gold, 40 mm across. The case measures 11.9 mm thick, with a lug width of 20 mm. A black monobloc Cerachrom bezel in ceramic carries a moulded tachymetric scale, and a scratch-resistant sapphire crystal covers the bright black and Sundust dial. Inside is the calibre 4131, a self-winding mechanical chronograph with 72 hours of power reserve. The dial combines a small seconds subdial with luminous hands and indices, and Rolex certifies the movement as a chronometer. The watch is fitted to a rubber Oysterflex bracelet with a folding Oysterlock safety clasp in rose gold, complete with the Glidelock extension system. Rolex rates the case to 100 metres.
