The tachymetric scale
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 kilometers 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.
This model’s Black 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.
Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.
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 Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Fink's Jewelers is proud to be part of the worldwide network of Official Rolex Jewelers 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 kilometers or miles per hour, as they choose. An icon eternally joined in name and function to the high‑performance world of motor sport.
