Description
This Oyster Perpetual Cosmograph Daytona in 18 ct Everose gold, with a bright black and Sundust dial and an Oyster bracelet, features an 18 ct Everose gold bezel with an engraved tachymetric scale.
The tachymetric scale
High-performance chronograph
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 black and Sundust dial
With chronograph counters
This model features a bright black and Sundust dial with snailed counters, 18 ct 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 Everose gold
An exclusive patent
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 Oyster bracelet
Alchemy of form and function
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.
