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 Everose gold

To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.

The Tachymetric Scale

A key part of the model?s identity is the bezel moulded with a tachymetric scale for measuring average speeds of up to 400 miles or kilometres per hour. Blending of high technology with sleek aesthetics, the black bezel is reminiscent of the 1965 model that was fitted with a black Plexiglas bezel insert. The monobloc Cerachrom bezel in high-tech ceramic offers a number of advantages: it is corrosion resistant, virtually scratchproof and the colour is unaffected by UV rays. This extremely durable bezel also offers an exceptionally legible tachymetric scale, thanks to the deposition of a thin layer of platinum in the numerals and graduation via a PVD (Physical Vapour Deposition) process. The monobloc Cerachrom bezel is made in a single piece and holds the crystal firmly in place on the middle case, ensuring waterproofness.
