Early Rolex Cosmograph Daytona models have marked a historical era for the manufacturer and is today one of the most celebrated and sought after timepieces by collectors. The ref. 6240 is one of the most important Daytona models produced. First released in 1965, it was the first reference to feature waterproof screwed-down pushers, a feature that still exists in current Daytona models. Only in production until 1969, it is estimated that approximately only 1,700 examples of the reference were produced over its production span.

Dubbed as the “Small Daytona” by collectors, the present attractive specimen features a small “DAYTONA” designation below “COSMOGRAPH” at 12 o’clock. Furthermore, a keen eye may notice the absence of the two sigma symbols next to the “T SWISS T” designation at 6 o’clock, a trait that is correct for this specific dial variant. Adopting a black bezel insert, the ref. 6240 features Mk1 screwed-down pushers with a correct Twinlock 700 crown.

The present timepiece is a clean example of the rare and highly sought after reference featuring all the desirable features a collector would want in a ref. 6240 “Small Daytona”. Bearing a 1.4 million serial from circa 1966, the present example is most likely one of the last of the variant produced. Nonetheless a treat for vintage Daytona lover’s to add a desirable and rare example to their collection.
