The tachymetric scale
A key part of the model’s identity is the bezel moulded with a tachymetric scale for measuring average speeds of up to 400 miles or kilometres per hour. Blending high technology with sleek aesthetics, the black bezel is reminiscent of the 1965 model that was fitted with a black Plexiglas bezel insert.
The monobloc Cerachrom bezel in high-tech ceramic offers a number of advantages: it is corrosion resistant, virtually scratchproof and the colour is unaffected by UV rays. This extremely durable bezel also offers an exceptionally legible tachymetric scale, thanks to the deposition of a thin layer of platinum in the numerals and graduations via a PVD (Physical Vapour Deposition) process. The monobloc Cerachrom bezel is made in a single piece and holds the crystal firmly in place on the middle case, ensuring waterproofness.
White dial
This model features a white dial with snailed 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.
Oystersteel
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.
Models 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.
Fung Leung Kee Watch is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
