This Oyster Perpetual Cosmograph Daytona in 18 ct yellow gold, with a golden, diamond-set dial and an Oyster bracelet, features a diamond-set bezel and diamond-set lugs.

This model features a golden, diamond-set dial with spray-coated counters, 18 ct gold applique hour markers and hands with a Chromalight display, a highly-legible luminescent material. The dial allows drivers to accurately map out their track times and tactics without fail.

The timepiece incorporates a bezel adorned with 36 trapeze-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.

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 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.

The new-generation Cosmograph Daytona is equipped with calibre 4131, a chronograph movement unveiled this year, entirely developed and manufactured by Rolex. A distillation of technology, this self-winding mechanical movement delivers outstanding performance in terms of precision, power reserve, convenience and reliability. It incorporates a chronograph function with a reduced number of components, thereby also enhancing the movement’s reliability. It is engaged by a robust mechanism with a column wheel and vertical clutch, allowing an instantaneous and extremely precise start. The bridges of calibre 4131 feature a Rolex Côtes de Genève decoration, which differs from the traditional Côtes de Genève by the addition of a slight polished groove between each band.
