Mother-of-Pearl Dial
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.

Diamond-set bezel
The timepiece incorporates a bezel adorned with 36 brilliant-cut diamonds. This now legendary chronograph is the instrument of choice for measuring time intervals and determining average speeds. On this gem-set version, the emblematic tachymetric scale is replaced with diamonds.

The Oysterflex Bracelet
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.
