The Rolex Cosmograph Daytona reference 6239 was launched in 1963, replacing the earlier pre-Daytona reference 6238. This introduction marked a transformative moment in the history of Rolex chronographs, setting the stage for decades to come. Iconic and cherished by collectors worldwide for its classic design, robustness, and masculine appeal, the Daytona would become one of the most significant timepieces ever released, with specific examples achieving impressive results at auction.

Evolving from its predecessor, the first Daytona featured a solid metallic bezel with a tachymeter scale inscribed for the first time, a departure from the smooth bezel of earlier models. The dial showcased a bi-colored theme with contrasting registers, replacing the former monochromatic design. Retaining the pump-style pushers derived from the reference 6238, early examples of the 6239 housed the same cal. 72B movement as its pre-Daytona counterparts. In 1964, Rolex sponsored both the French Le Mans 24-hour endurance race and the American Daytona 24-hour endurance races. While the Cosmograph was initially intended for the European market, the Daytona inscription was specifically aimed at the American audience. Ultimately, it became clear that “Daytona” would be the definitive name.

The present example from circa 1964 with a 1 million serial number represents a rare find for vintage Rolex collectors. This early model features the sought-after small “Floating Daytona” designation beneath its signature and is double-signed by one of the most prestigious watch retailers: Tiffany & Co, where a similar example with a silvered dial is prominently documented in the Ultimate Rolex Daytona book by Pucci Papaleo. The signature is identical on both instances of the 6239, down to the subtle details of the slightly warped letters.

With all the correct components—including an early 300-unit bezel, its “T SWISS T” inscription at 6 o’clock in the desirable style, a cal. 72B stamped with ROW indicating it was originally sold in the U.S. market, and a Rolex U.S.A. Oyster deployant clasp—this example is truly exceptional.

Boasting an attractive case and a dial that has aged beautifully over time, coupled with the recent surge in demand for Tiffany & Co. signed timepieces, this reference 6239 is sure to impress discerning aficionados of vintage Rolex wristwatches.
