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.
CHAMPAGNE-COLOR AND BLACK DIAL
This model’s Champagne-color and black dial with snailed counters features 18 kt 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.
18 KT YELLOW GOLD
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. 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.
