The Rolex Cosmograph Daytona 6240 was first introduced in the mid-1960s and was produced until around 1969. It was a very important model because it was the first Daytona to have screw-down pushers, making it more water-resistant. Exact production numbers are not known, but it is considered rare today.
The 6240 shows up on the secondary market from time to time, but it is highly sought after by collectors who appreciate its unique features and place in Rolex history.
The 6240 is significant for being the first model to have “Oyster” written on the dial, showing that it was more water-resistant than previous versions. It used the manual-wind Valjoux 72 movement, like other early Daytonas, and helped set the design style for future models.
On the outside, the 6240 looks different with its screw-down pushers, which help keep water out. It also has the same steel bezel with a tachymeter scale, and its 37mm case is smaller than today’s Daytona models.
