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.
18 ct white gold
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.Model Availability
