Oyster Perpetual Cosmograph Daytona
The Oyster Perpetual Cosmograph Daytona is the benchmark for those with a passion for driving and speed. An iconic model created in 1963, the Cosmograph Daytona was designed to meet the timing needs of professional endurance racing drivers. Fitted with a tachymetric graduated bezel to measure average speed and a high- performance mechanical movement entirely developed and manufactured by Rolex, this chronograph is legendary for its reliability.
A CHRONOGRAPH MADE FOR THE ROAD
The Rolex Cosmograph Daytona was designed to be the ultimate timing tool for racing drivers thanks to its precision, reliability and the outstanding legibility of its functions. Time intervals can be measured to within one-eighth of a second with the centre chronograph seconds hand, while the two counters on the dial at 3 and 9 o’clock display elapsed time in minutes and hours respectively.
THE COSMOGRAPH DAYTONA, SUPERLATIVE CHRONOMETER
Like all Rolex watches, each Cosmograph Daytona is certified as a Superlative Chronometer. This exclusive designation attests that it has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed normal watchmaking standards. These tests are carried out on the fully assembled watch, in order to guarantee its superlative performance on the wrist.
THE OYSTER CASE, SYMBOL OF WATERPROOFNESS
The Cosmograph Daytona’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a symbol of robustness. The characteristically shaped middle case is crafted from a solid block of 18 ct gold, 950 platinum or particularly corrosion-resistant 904L steel. The fluted case back is screwed down with a special tool that grants only Rolex watchmakers access to the movement.
PERPETUAL CALIBRE 4130
The Cosmograph Daytona is equipped with calibre 4130; a self-winding mechanical chronograph movement entirely developed and manufactured by Rolex. Its architecture, a composite of Rolex technology, was completely re-engineered: the number of components for the chronograph function was reduced significantly, thereby enhancing the movement’s reliability. The chronograph is engaged by a mechanism with a column wheel and vertical clutch. This enables an instantaneous and extremely precise start to the timing, and is extremely robust.

Founded by Hans Wilsdorf in 1905, Rolex pioneered the development of the wristwatch and is at the origin of numerous major watchmaking innovations, such as the Oyster, the first waterproof wristwatch, launched in 1926, and the Perpetual rotor self-winding mechanism invented in 1931. Rolex has registered over 400 patents in the course of its history. A truly integrated and independent manufacturing company, Rolex designs, develops and produces in-house all the essential components of its watches, from the casting of the gold alloys to the machining, crafting, assembly and finishing of the movement, case, dial and bracelet. Rolex is also actively involved in supporting the arts, sports, exploration, the spirit of enterprise, and the environment through a broad palette of sponsoring activities, as well as philanthropic programmes.
