Rolex Cosmograph Daytona 40 mm

The Rolex Cosmograph Daytona 126589RBR-0001 is a 40 mm chronograph in white gold. The case measures 11.9 mm thick, with a lug width of 20 mm. A screw-down crown seals the monobloc middle case, and a sapphire crystal protects the white and black mother-of-pearl dial, set with diamonds. The diamond-set bezel replaces the usual tachymetric scale on this version. Inside is calibre 4131, a self-winding chronometer movement with 72 hours of power reserve, driving the small seconds and chronograph counters. Luminous hands and indices keep the display legible. The rubber bracelet closes with a folding clasp in white gold, fitted with the Rolex Glidelock extension system. Rolex rates the case to 100 metres.
