Ice-Blue Dial
This model features an ice-blue 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.
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. 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.
Platinum
Rare and precious, platinum is striking for its silvery whiteness and vibrant luminosity. It is among the densest and heaviest metals in the world, distinguished by unique chemical and physical properties such as exceptional corrosion resistance. Paradoxically, it is also soft, elastic and highly malleable, which makes machining and polishing especially difficult, demanding an extremely high degree of skill. Rolex always uses 950 platinum, an alloy consisting of 950‰ (thousandths) platinum, painstakingly crafted in-house by the fine metalworkers at Rolex. The noblest of metals for the finest of watches.
