Subsequent Models of Rolex Cosmograph "Daytona"

Over the years, Rolex came out with the following new Daytona models, each showing some technological improvements over the previous models in some way or another:

Model 6262 & 6264: In 1965, model 6262 replaced the model 6239, while the model 6464 replaced the model 6241. These models were an improvement over the earlier versions as they utilized a new Valjoux 727 movement.

Model 6240: It was a completely new model, also launched in 1965. Its unique feature was its screw down waterproof pushers making it waterproof to a level of 165 feet. It was also the first Rolex Daytona that had "Oyster" engraved on its dial.

Model 6263 & 6265: Introduced in 1971, model 6263 was an improved version of Model 6262, while model 6265 improved upon model 6264. These improved versions featured the new screw-down waterproof pushers. They were also the first Daytona models to use a new larger Triplock winding crown.

Model 16520/16523/16528: These models include the new Oyster Perpetual Cosmograph Daytona, launched in 1988. While the tachymeter scale present in these models calibrated to the usual 200 units per hour, it was soon thereafter upgraded to 400 units per hour (as can be found in all current Daytona models). The only difference between these models was that while model 16520 was available in stainless steel, model 16523 was available in a combination of stainless steel and 18k yellow gold (two-tone) and model 16528 was available in 18k yellow gold only. These models were powered by caliber 4030 Zenith El Primero movement, which gave them an edge over previous models in terms of performance.

Model 16518: Rolex launched a new Oyster Perpetual Cosmograph Daytona watches model in 1992, which was made available only in 18k yellow gold. It also featured a leather strap and safety deployment clasp. It was different from the earlier models due to its bezel, which sported small triangles in place of small dots pointing to the individual calibrated numbers.

Model 16519: Introduced in 1997, it was similar to model 16518, the only difference being that it was made of white gold.

Rolex Cosmograph Also Known as the Paul Newman and Daytona

In the car racing film Winning, the star Paul Newman was seen wearing a Rolex Cosmograph with an exotic dial. Later, he made appearances in movie posters and some popular Italian magazines, reportedly flaunting his Rolex Cosmograph collection. This publicity fueled the popularity of all versions of the Rolex Cosmograph watches with contrasting registers (having square markers within), and they became popularly known as Paul Newmans. This Rolex model was already an instant hit in the auto racing market due to their usefulness in calculating average lap speed. However, the association of Paul Newman with this model resulted in a huge publicity windfall.

The model is also popularly known as Daytona after the world famous Daytona Beach in Florida, which has created and continues to foster legendary racers and racing icons.
