Rolex Daytona 6239 Baby Blue

While Rolex had been producing chronographs since the 1930s, it wasn’t until the release of reference 6239 that the model was officially named and defined. The 6239 introduced two major firsts for Rolex chronographs: contrasting color sub-dials and an engraved tachymeter bezel. Produced from 1963 through roughly 1970, it marked the beginning of what would become one of Rolex’s most iconic lines.

The circa 1970 example here features a black dial with white sub-registers and “Daytona” printed above the six o’clock register. Collectors often refer to this variant as the “Blue Daytona” due to the subtle blue-grey hue of the Daytona text—seen only on the final batches of the 6239 and the following 6262 models with black dials. This watch is in great, honest condition and ideal for someone seeking a classic steel bezel, pump-pusher Daytona with a twist. These “blue” 6239s tend to fly under the radar, appealing to collectors who appreciate the discreet, “if you know, you know” charm.
