Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126515LN-0010 is a chronograph with a 40 mm case in Everose gold. The case measures 11.9 mm thick, with lugs set 20 mm apart. Rolex fits a monobloc black Cerachrom bezel with a tachymetric scale, milled in ceramic and completed with a scratch-resistant sapphire crystal. The self-winding calibre 4131 drives the watch, with a chronograph and small seconds subdial, and carries chronometer certification. Hands and indices carry luminous treatment for legibility. The chocolate and black dial sits on an Oysterflex bracelet, a rubber-moulded design closed with a folding Oysterlock clasp in rose gold and Rolex's Glidelock extension system. Rolex rates the case to 100 metres.
