The triumph of endurance
This Oyster Perpetual Cosmograph Daytona in 18 kt white gold, with a black and white mother-of-pearl, diamond-set dial and an Oyster bracelet, features a diamond-set bezel.
Mother-of-Pearl Dial
A unique effect
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
Adorning a legendary chronograph
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 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.
The Oyster bracelet
Alchemy of form and function
The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty.
The Oyster bracelet is a perfect alchemy of form and function. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection.
