The tachymetric scale
With its tachymetric scale, its three counters and its pushers, the Cosmograph Daytona was designed to be the ultimate timing tool for endurance racing drivers. The bezel features a tachymetric scale to read average speed over a given distance based on elapsed time.

Black and Champagne-colour Dial
This model’s Black and champagne-colour dial with snailed counters features 18 ct gold applique hour markers and hands in Chromalight, a highly-legible luminescent material. The central sweep seconds hand allows an accurate reading of 1/8 second, while the two counters on the dial display the lapsed time in hours and minutes. Drivers can accurately map out their track times and tactics without fail.

18 ct yellow 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.
Siam Swiss 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.
