Swiss watchmaker Rolex introduced the Cosmograph Daytona in the year 1963. It was designed to meet the demands of racing drivers on a professional level. The Cosmograph Daytona is an icon in luxury watchmaking that has forever joined, in name as well as function, the high-performance world of motorsports. Today, over 50 years after its inception, the Cosmograph Daytona remains in a league of its own among numerous sport chronographs as it carries on and transcends time itself.
The Oyster Perpetual Cosmograph Daytona has turned into a superlative tool watch for those with a passion for speed and driving.

The Dial
With the tachymetric scale of the watch, the three counters, and pushers on the side of the case, the Cosmograph Daytona was designed to be the unrivalled timing tool for race car drivers. The chronograph on the timepiece allows drivers to measure elapsed time. This time is displayed in hours, minutes and seconds on the dial itself.
The hours and minutes are shown on the watch’s distinctive counters located at 9 o’clock and 3 o’clock, respectively. The seconds are read via the centre hand with the arrow-tipped head along with the 60-second scale around the dial.
The Bezel
The bezel of the watch features a tachymetric scale. This tool enables users to read average speed over a given distance as per elapsed time. Offering optimal legibility, the tachymetric scale makes the Cosmograph Daytona the perfect tool for measuring speeds up to 400 units per hour. This speed can be read in kilometres per hour or in miles per hour.
The Chronograph
The Rolex Daytona’s chronograph feature is activated by its pushers. These pushers screw down like the winding crown when they are not being used. The usage is as simple as it can get. One press to start, stop or reset the chronograph. The pushers produce a clear and crisp click. Watchmakers at Rolex mastered the mechanism to suit the ideal finger pressure of race car drivers on the pushers. They engineered it just perfectly to offer an instant and precise start to the timing.
The Movement
The Rolex Cosmograph Daytona is presented fitted with calibre 4130. Developed and manufactured by Rolex itself, the mechanism is a self-winding mechanical chronograph movement. Its design uses fewer components than a standard chronograph. It not only saves space in order to house a large mainspring and, therefore, deliver a power reserve of 72 hours but it also improves the movement’s dependability. Calibre 4130’s high performance can be linked to the implementation of a vertical, instead of a lateral clutch, which eventually activates the chronograph.
This mechanical system functions on the principle of two discs, one above the other, which work together by direct friction contact and offer significant advantages: the precision of the start and stop functions as well as the smooth running of the chronograph seconds hand as soon as the pusher is pressed; and the capacity of the chronograph to function for long periods of time with no negative impact on the precision of the watch.
The Rolex Cosmograph Daytona has been and forever will be a symbol of excellence in modern-day Haute Horlogerie. The Rolex Daytona is nothing but a masterpiece of engineering and micromechanics, replete with a high-performing movement and innovative technical solutions. The watch has set a new standard in the world of luxury chronographs in terms of robustness, precision, and efficiency. The Swiss watchmaker’s chronograph, staying true to its motto, is truly a watch born to race.
