TACHYMETRE
The Daytona’s engraved bezel can be used as a tachymetre to help read distance in combination with an elapsed time. The Cosmograph Daytona is therefore a perfect instrument for measuring speed up to 400 units per hour whether they be kilometres, miles or any other reference unit.

START. DRIVE. STOP
At Rolex, form and function work together. Rolex engineers have applied the most advanced of technologies in crafting the perfect spring to activate the chronograph mechanism when finger pressure is exerted on the pushers. The result is not only a reliable stopwatch function, but also a crisp, clear “click” sound well known by those who wear this oneof- a-kind timepiece, whether they be measuring laps or indeed recording any elapsed period of time.

4130 CHRONOGRAPH MOVEMENT
Inside the elegantly designed exterior, the Cosmograph Daytona is a masterpiece of watch making art. The 4130 chronograph calibre movement was conceived and assembled exclusively by Rolex in 2000 for the Cosmograph Daytona and incorporates just 290 components – far fewer than a standard chronograph – making it a much admired symphony of simplicity. It has a 72-hour Power reserve (66 hours if the stopwatch is in use) and, inside, the blue Parachrom hairspring, made from a unique alloy impervious to magnetic fields, gives it up to 10 times more resistance to shocks than conventional hairsprings.
