The Rolex Cosmograph Daytona ref. 126508 is a men's chronograph watch with a 40mm round case in 18k yellow gold. It has a fixed 18k yellow gold bezel with an engraved tachymetric scale and a scratch-resistant sapphire crystal. It is worn on an Oyster bracelet with three-piece solid links.
It is powered by the Rolex caliber 4131, a self-winding mechanical chronograph movement. The centre hands show hours and minutes, and a small seconds hand sits at 6 o'clock. The chronograph runs from the centre seconds hand, with a 30-minute counter at 3 o'clock and a 12-hour counter at 9 o'clock. A stop-seconds function allows exact time setting.
The screw-down case back and winding crown use the Triplock triple waterproofness system. The watch is water resistant to 100 meters (330 feet). The bracelet closes with a folding Oysterlock safety clasp that has an Easylink 5 mm comfort extension link.
