This model’s Black set with diamonds dial with snailed counters features 18 ct gold applique hour markers and hands in Chromalight, a highly-legible luminescent material.
The tachymetric scale
<p>A key part of the model’s identity is the bezel engraved 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. </p>
<p>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.</p>
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
All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity.
Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Retailers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
John Pass is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
The Rolex Cosmograph Daytona, introduced in 1963, was designed to meet the demands of professional racing drivers. With its highly reliable chronograph and bezel with tachymetric scale, it allows drivers to perfectly measure average speeds up to 400 kilometres or miles per hour, as they choose. An icon eternally joined in name and function to the high‑performance world of motor sport.
