Cosmograph Daytona, 18 ct yellow gold

With its tachymetric scale, three counters, and pushers, the Cosmograph Daytona was designed to be the ultimate timing tool for endurance racing drivers. The bezel features a tachymetric scale for reading average speed over a given distance based on elapsed time. This scale offers optimum legibility, making the Cosmograph Daytona the ideal device for measuring speeds of up to 400 units per hour, whether expressed in kilometres or miles. 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 possesses an unrivalled ability to cast the highest-quality 18 ct gold alloys in its own exclusive foundry. Different types of 18 ct gold are obtained depending on the proportion of silver, copper, platinum, or palladium added: yellow, pink, or white. They are crafted exclusively from the purest metals and meticulously examined in an in-house laboratory equipped with state-of-the-art equipment, before the gold is shaped and fashioned with the same exacting attention to quality. Rolex's commitment to excellence begins at the source. 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.
