Description
This Oyster Perpetual Cosmograph Daytona in 18 ct white gold, with a steel, diamond-set dial and contrasting counter rings, features an Oysterflex bracelet as well as a diamond-set bezel and diamond-set lugs.
The Oysterflex Bracelet
Highly resistant and durable
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.
18 ct white gold
Commitment to excellence
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.
Steel dial
With chronograph counters
This model features a steel, diamond-set dial with snailed 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.
Diamond-set bezel
Adorning a legendary chronograph
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.
