A similar slightly earlier example can be found in Ultimate Rolex Daytona by Pucci Papaleo Editions, page 34.

First introduced in 1963, the Daytona reference 6239 marked a step forward in the progression of Rolex’s chronograph, characterized by the incorporation of a fitted tachymeter bezel, originally devised to enable the calculation of average speeds and lap times for automobile aficionados. Indeed, from the mid-1960s on this reference begins to be known as the Daytona in allusion with the renowned racetrack in Florida.

The present example, produced circa 1967 and exhibiting an alluring patina, bears  the 1’599’530 serial number, thus ranking among the first specimens of this reference to showcase Daytona at 6 o’clock, establishing a direct connection to the Cherry logo -albeit in black and even spacing between the letters- and consequently a highly collectible piece.

This reference features push-down buttons and an Oyster Twinlock winding crown with a 2nd series metal bezel calibrated to 300. The case further follows the usual Rolex design for the reference, sporting a two-toned dial with an interesting and unusual speckled white patina evenly displayed across the subsidiaries. The caliber of the present example is a manual Valjoux 722 with 17 jewels, a movement only found on this reference for a brief period, between 1965 and 1967, which greatly enhances its singularity.
