This chronograph was designed to be the ultimate timing tool for endurance racing drivers. More than 50 years after its creation, the Cosmograph Daytona remains in a class of its own amongst sports chronographs and continues to transcend time. The Daytona’s chronograph feature functions are activated by pushers that screw down like the winding crown when they are not in use, guaranteeing waterproofness to 100 meters. One press to start, stop or reset the chronograph produces a crisp, clear click that was perfected using the most advanced technology. Rolex watchmakers also perfected the mechanism to suit the ideal finger pressure on the pushers and engineered it to provide an instantaneous and accurate start to the timing without sacrificing reliability.

By operating its own exclusive foundry, Rolex has the unrivaled ability to cast the highest quality 18 ct gold alloys. They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex's commitment to excellence begins at the source. This particular model was cast in white gold with a steel and black dial along with a hybrid metal and elastomer band to create a luxurious but easily wearable 40mm watch. This particular watch is USED, but was worn with care so shows very little signs of use. This watch also comes with its full authentication papers and boxes.

The new Cosmograph Daytona is fitted with an Oysterflex bracelet, developed and patented by Rolex. At its core lies a superelastic metal blade over-molded with high-performance black elastomer, a material that is particularly resistant to environmental effects and very durable. The Oysterflex bracelet is also fitted with an Oysterlock safety clasp and is equipped with the Rolex patented Easylink rapid extension system that allows the wearer to increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.

This model features a steel and black dial with snailed chronograph counters, gold applique hour markers, and hands with a Chromalight display, a highly-legible luminescent material. The central sweep seconds hand allows an accurate reading of 1/8 second, while the two counters on the dial display the lapsed time in hours and minutes. Drivers can accurately map out their track times and tactics without fail.

The Cosmograph Daytona is equipped with caliber 4130, a self-winding mechanical chronograph movement developed and manufactured by Rolex. Its architecture incorporates far fewer components than a standard chronograph, thereby enhancing the movement’s reliability. Like all Rolex Perpetual movements, the 4130 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The chronograph movement features a Parachrom hairspring, offering greater resistance to shocks and to temperature variations.
