Rolex Cosmograph Daytona Oyster, 40 mm, white gold and diamonds M126589RBR-0001

The 18 ct 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.

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 contrasting dial is made from natural mother-of-pearl and graced with eight diamonds and three Chromalight hour markers. The strength of the contrast, the intensity of the colours and the depth of the reflections are the result of a particularly stringent material selection process. Both varieties of mother-of-pearl are handled with the greatest care by the brand’s artisans. The dial allows drivers to accurately map out their track times and tactics without fail.
