Rolex Cosmograph Daytona 40 mm

The Rolex Cosmograph Daytona 126505-0005 is a 40 mm chronograph in Everose gold. The case measures 11.9 mm thick, with a lug width of 20 mm, and carries a fixed bezel with an engraved tachymetric scale. A scratch-resistant sapphire crystal covers the chocolate and black dial, which shows luminous hands and indices along with a small seconds subdial. Inside is the calibre 4131, a self-winding perpetual movement with a power reserve of approximately 72 hours. The watch is chronometer certified and its chronograph function is read off the tachymetric scale via the centre seconds hand. It is fitted with an Everose gold Oyster bracelet on a folding Oysterlock safety clasp with an Easylink extension link. The screw-down Triplock crown helps keep the case waterproof to 100 metres.
