In the 60’s Rolex made some changes in their chronograph line. They moved the tachymetric scale (used for measuring distance over time) from the dial to the bezel. The simplified dial also featured another change: contrasting coloured sub-dials. This gave the watch an even more sportive look, which was a good thing as it was dedicated to racing drivers, hence the name Daytona (a race held annually at the Daytona beach in Florida). Although Rolex has been making chronographs since the 30s, this is the first line that got named (in 1964). Nowadays it is one of the most sought after models of all time and comes in so many different variations, fetching prices from $8000 to $1.000.000. This is a big difference to the $210 that was the list price back then. But it was even often sold under the list price as the Daytona wasn’t a popular watch in its day. It wasn’t until 1986 that the demand for Daytona’s increased rapidly due to, mostly, Italian collectors and dealers.The 6239 is the first reference for the Rolex Cosmographs. This line was born in the early 60s and evolved from the 6238, being the first Rolex Chronograph with a tachymetre bezel and contrasting colours on the sub-dials. This change may not seem like much, but these two traits were very different and recognisable and started the legendary era of the Daytona. The last batch of the 6239 was produced in 1969 and features a dial that collectors call "The Blue" as the Daytona text has a blueish shade. This very rare piece even comes with the original box and papers. A true collectors dream.
