Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126505-0003 is a 40 mm case in 18 ct rose gold, a chronograph built for endurance timing. The case measures 11.9 mm thick, with a fixed bezel carrying an engraved tachymetric scale in the same rose gold. A sapphire crystal protects the Sundust and bright black dial, which pairs a chronograph layout with small seconds. The self-winding Calibre 4131 drives the watch, offering a chronometer-certified movement with 72 hours of power reserve. Hands and indices carry luminous treatment for legibility. The rose gold Oyster bracelet closes with a folding Oysterlock safety clasp that includes an Easylink comfort extension link. Rolex rates the case to 100 metres.
