Rolex Cosmograph Daytona 40 mm

Rolex Cosmograph Daytona 126519LN-0006 is a 40 mm chronograph in 18 ct white gold. The case measures 11.9 mm thick, with a lug width of 20 mm, and is fitted with a scratch-resistant sapphire crystal. A black ceramic bezel with a tachymetric scale surrounds the steel and bright black dial, which carries luminous hands and indices. The self-winding calibre 4131 drives the watch, with small seconds and chronograph functions including a tachymeter, and Rolex certifies it as a chronometer. Power reserve runs to approximately 72 hours. The Oysterflex bracelet, with its folding Oysterlock safety clasp and Glidelock extension system, closes in white gold. Rolex rates the case to 100 metres.
