Introduced by Rolex in 1963, the first aptly titled Cosmograph Chronograph (ref. 6238) was produced in limited quantities, and officially began the “Daytona” series. Although the original name in publication for the 6238 was “LeMans”, destiny obviously had other plans.
In our photo of the 6238 above, the name “Daytona” is nowhere to be found. This is due to the fact that the name “Daytona” was not included until the following production year (1964).
