Catalog Essay:

The reference 6239 was first released in 1963 and marks the official start of the now-iconic Rolex Daytona collection. While Rolex was producing chronograph wristwatches for a number of years prior to this point in time, it was the ref. 6239 that first moved the tachymeter scale from the dial to the bezel and forever set the standard for Rolex chronograph watches.

The Rolex Daytona 6239 is characterized by its manual-wind movement, metal bezel, and pump-style chronograph pushers. These early Rolex Daytona watches pre-date the implementation of screw-down pushers, and consequently do not have the ‘Oyster’ designation on their dials. Additionally, the ‘Daytona’ name did not start appearing on Rolex chronograph dials until around 1965, so this particular model with an estimated production date of 1966 represents some of the earliest Daytona-branded watches, with the ‘DAYTONA’ name appearing directly below the word ‘COSMOGRAPH’ on the upper half of the dial, rather than above the register at 6 o’clock like later-era examples.

Reference 6239 Daytona watches were offered in either stainless steel or yellow gold, and the steel models were typically fitted with either black dials with white registers, or silver dials with black registers, like this particular example. Additionally, similar to all vintage Rolex Daytona watches that pre-date the arrival of self-winding movements, the ref. 6239 has a case diameter of 37mm and lacks crown-guards like subsequent Daytona generations.


MOVEMENT: Chronograph is functioning. This vintage Rolex Daytona comes with Bob's Watches one year warranty.
