This Oyster Perpetual Cosmograph Daytona in 18 ct yellow gold, with a bright black and golden, diamond-set dial and an Oyster bracelet, features an 18 ct yellow gold bezel with an engraved tachymetric scale.
This model features a bright black and golden, diamond-set dial with spray-coated 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.
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.
By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 kt gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 kt gold are obtained: yellow, pink or white.
The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty.
The Oyster bracelet is a perfect alchemy of form and function. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection
