Rolex

Introduced in the mid-1960’s, the reference 6240 was the first Daytona to incorporate screw-down pushers and thus became the first true waterproof Cosmograph model to be produced by Rolex. Manufactured solely in stainless steel, the chronograph also features an acrylic tachometer bezel calibrated to 200. There were a few different dial variations found on the reference 6240. Early examples such as the present watch are distinguished by the lack of ‘Oyster’ written on the dial, not yet referring to the screw down pushers. Instead, this example features a dial version better known on the reference 6239 with the ‘small’ Daytona designation. This shows that Rolex was still using the non-Oyster 6239 dials for some of the new reference 6240 watches. The next dial type was similar but with the model name ‘Daytona’ now in larger text. It was only for the later examples of reference 6240 did Rolex fit a dial with the ‘Oyster’ designation.

Making the transition from pump to screw-down pushers, which have been used ever since, the Reference 6240 marks an important shift in the history of the Daytona. This role makes it a particularly important and collectible model for educated collectors.

This example has remained until today in the family of its original owner. Absolutely fresh to the market, it is further accompanied by its original Rolex Guarantee, a rarity on its own.
