Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126539TBR-0002 is a 40 mm chronograph in white gold. The case measures 11.9 mm thick, with a lug width of 20 mm, and is set with diamonds on the bezel and lugs. A sapphire crystal covers the steel dial, which has bright black counter rings set with diamonds. The self-winding calibre 4131 drives the watch, offering 72 hours of power reserve and chronometer certification. Small seconds sits at six o'clock alongside the chronograph counters, and the hands and indices carry luminous treatment for legibility. The Oysterflex strap, a flexible rubber band over metal blades, closes with a folding Oysterlock clasp with Glidelock extension. Rolex rates the case to 100 metres of water resistance.
