          Description

          The triumph of endurance

          This Oyster Perpetual Cosmograph Daytona in 18 kt white gold, with a meteorite and black dial and an Oysterflex bracelet, features a black Cerachrom bezel with tachymetric scale.

           

          Meteorite dial

          An alloy from outer space

          This model is the only Cosmograph Daytona with a meteorite dial. Meteorite comes from the heart of an asteroid or possibly even a planet that has exploded, propelling material across the Solar System until chance brings it into our planet’s orbit and gravity pulls it to Earth.

          During its journey, the centre of the meteorite is gradually transformed, producing highly unusual metallic patterns, resulting from the very slow cooling of molten asteroid cores. The designers at Rolex create from these configurations a unique treasure for some of the most prestigious models, including this Cosmograph Daytona.

           

          The tachymetric scale

          High-performance chronograph

          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 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 graduations 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.

           
           

          The Oysterflex Bracelet

          Highly resistant and durable

          The 18 kt gold versions of the Cosmograph Daytona with a Cerachrom bezel are available with an Oysterflex bracelet. Developed by Rolex and patented, it singularly combines the robustness of a metal bracelet with the comfort of an elastomer bracelet.

          It is made up of two flexible curved metal blades – one in each bracelet section – overmoulded with high-performance black elastomer. For optimum comfort, the Oysterflex bracelet is equipped with cushions on its inner sides and an Oysterlock safety clasp to prevent accidental opening. Its length may be adjusted via the ingenious Rolex Glidelock extension system.

           

          18 kt white gold

          Commitment to excellence

          By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 kt gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 kt 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.
