Rolex Cosmograph Daytona 126505-0001 is a 40 mm case in rose gold, a chronograph built for endurance timing. The case measures 11.9 mm thick, with a fixed rose gold bezel carrying an engraved tachymetric scale. A screw-down crown secures the case, and the dial, finished in bright black and Sundust, sits under a scratch-resistant sapphire crystal. Hands and indices are luminous for legibility in low light. Inside is the calibre 4131, a self-winding chronograph movement offering 72 hours of power reserve and certified as a chronometer. The watch includes small seconds and a tachymeter function alongside the chronograph. It is fitted with a rose gold Oyster bracelet and a folding Oysterlock clasp with an Easylink extension link. The case is waterproof to 100 metres.
