Rolex Cosmograph Daytona 40 mm

Rolex's Cosmograph Daytona 126518LN-0006, a chronograph in 18 ct yellow gold, measures 40 mm across and 11.9 mm thick. The black monobloc Cerachrom bezel carries a tachymetric scale and holds the sapphire crystal firmly against the case. The bright black and golden dial is set with diamonds and shows luminous hands and indices. Inside runs the calibre 4131, a self-winding chronograph movement with 72 hours of power reserve and Rolex's chronometer certification. The dial also carries small seconds and the chronograph counters that define the model. An Oysterflex bracelet completes the watch, its flexible metal blades overmoulded in black elastomer and closed with a folding Oysterlock clasp in yellow gold with Glidelock extension. Water resistance reaches 100 metres, a figure tied to the screw-down Triplock crown.
