Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126500LN-0002 is a chronograph in steel measuring 40 mm across and 11.9 mm thick. The monobloc middle case has a screw-down winding crown and a black ceramic bezel moulded with a tachymetric scale. The dial is black with steel counter rings, and the hands and indices carry luminous treatment. A scratch-resistant sapphire crystal covers the dial. Inside is the calibre 4131, a self-winding chronograph movement with 72 hours of power reserve and Superlative Chronometer certification. Small seconds sits at 6 o'clock, and the chronograph adds a 30-minute counter alongside the tachymetric scale. The steel Oyster bracelet closes with a folding Oysterlock safety clasp, and the case is rated to 100 metres of water resistance.
