This Oyster Perpetual Cosmograph Daytona in 18 ct yellow gold with a champagne-colour and black dial and an Oysterflex bracelet, features a Black Cerachrom bezel with tachymetric scale.
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 among sport chronographs and continues to transcend time.
This Oyster Perpetual Cosmograph Daytona in 18 ct yellow gold with a champagne-colour and black dial and an Oysterflex bracelet, features a Black Cerachrom bezel with tachymetric scale.
A key part of the model’s identity is the bezel moulded with a tachymetric scale for measuring average speeds of up to 400 miles or kilometres per hour. Blending of high technology with sleek aesthetics, the black bezel is reminiscent of the 1965 model that was fitted with a black Plexiglas bezel insert.
The monobloc Cerachrom bezel in high-tech ceramic offers a number of advantages: it is corrosion resistant, virtually scratchproof and the colour is unaffected by UV rays. This extremely durable bezel also offers an exceptionally legible tachymetric scale, thanks to the deposition of a thin layer of platinum in the numerals and graduation via a PVD (Physical Vapour Deposition) process. The monobloc Cerachrom bezel is made in a single piece and holds the crystal firmly in place on the middle case, ensuring waterproofness.
This model’s Champagne-colour and black dial with snailed counters features 18 ct gold applique hour markers and hands in Chromalight, 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.
By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 ct gold are obtained: yellow, pink or white. 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.
The new Cosmograph Daytona is fitted with an Oysterflex bracelet, developed and patented by Rolex. At its core lies a superelastic metal blade overmoulded 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.
The Cosmograph Daytona is equipped with calibre 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.
