The Oyster Perpetual Cosmograph Daytona was designed to meet the needs of professional racing drivers. The Cosmograph Daytona is the benchmark for those with a passion for driving and speed. It has been manufactured by Rolex since 1963 in three distinct generations: the second series was introduced in 1988, and the third in 2000. While cosmetically similar, the second series introduced a self-winding movement, and the third series brought manufacture of the movement in-house to Rolex. The current Cosmograph Daytona is equipped with a tachymetric scale, a sweep seconds hand for reading to 1/8 of a second, and elapsed-time hours and minute displays. With a 40mm case, it is available in a variety of materials.
