Cosmograph Daytona, Oystersteel

An essential part of the model's identity, the moulded bezel features 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 recalls the 1965 model fitted with its black Plexiglas bezel insert. The monobloc Cerachrom bezel made from high-technology ceramic offers a number of advantages: it is corrosion-resistant, virtually scratchproof, and its colour is unaffected by UV rays. This highly durable bezel also offers an exceptionally legible tachymetric scale thanks to the deposition of a thin layer of platinum in the numerals and graduations through PVD (Physical Vapour Deposition). The monobloc Cerachrom bezel is made in a single piece and holds the crystal firmly in place on the middle case, ensuring waterproofness. This model features a black dial with snail-design counters, 18 ct gold applied hour markers, and hands with Chromalight display — a highly legible, luminescent material. The dial allows drivers to map out their lap times and strategies with flawless precision. Rolex uses Oystersteel for its steel watch cases. Specifically 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 durable, offers an exceptional finish once polished, and maintains its beauty even in the harshest environments. The design, development, and production of Rolex bracelets and clasps, as well as the rigorous tests they endure, require advanced high technology. As with all components of the watch, aesthetic controls performed by the human eye guarantee flawless 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.
