Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126503-0004 is a chronograph in steel and yellow gold, measuring 40 mm across and 11.9 mm thick. The fixed bezel carries an engraved tachymetric scale in yellow gold, and the golden dial with black counter rings sits under a scratch-resistant sapphire crystal. Inside is the calibre 4131, a self-winding chronograph movement with 72 hours of power reserve and chronometer certification. The layout keeps a small seconds subdial and chronograph counters, with luminous hands and indices for low-light legibility. A screw-down crown completes the Oyster case. The bracelet is steel and gold with a folding Oysterlock clasp and an Easylink comfort extension link. Rolex rates the case to 100 metres.
