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. This scale offers optimal legibility, making the Cosmograph Daytona the ideal instrument for measuring speeds up to 400 units per hour, expressed in kilometres or miles.
Bright blue dial
This model features a bright blue dial with snailed counters, gold applique hour markers and hands with a Chromalight display, 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 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.
