The 6239 is the first true Cosmograph Daytona. It moves the tachymetric scale off the dial and onto an engraved steel bezel, and brings contrasting sub-dial colours to the Rolex chronograph line for the first time. Production runs from 1963 to 1969, overlapping the late pump-pusher 6238 it replaced and the early screw-pusher 6240 it ushered in. | The 6239 is the first true Cosmograph Daytona.

Estimated production was roughly 14,000 examples in steel and about 300 in 18k yellow gold. | ||

Most sources date production to 1963–1969. Pucci Papaleo’s catalogue work includes some gold examples dated 1970. | |||
Serial bands pin the broad sequence even where exact years drift by a few months between sources: Mark 1 at the start, Daytona text added in 1964, dial text moved above the 6 o'clock sub-dial in 1967, and the bezel scale cut from 300 to 200 in the same late-1960s window. | Serial bands pin the broad sequence even where exact years drift by a few months between sources: Mark 1 at the start, Daytona text added in 1964, dial text moved above the 6 o'clock sub-dial in 1967, and the bezel scale cut from 300 to 200 in the same late-1960s window. | ||

Early Mark 1 watches are identified by a cluster of traits — the underline reads as part of the radium-to-tritium transition.

The Paul Newman dial sold poorly when new and became sought after decades later. | ||

The 6239 case is 36mm stainless steel, no crown guards, in the 3-6-9 chronograph idiom Rolex carried over from the 6238. It runs pump pushers throughout, never the screw-down design the 6240 introduces in 1965. The crown is a 7mm Twinlock signed with the Rolex coronet only, since the watch is not Oyster-rated and carries no "Oyster" designation. The crystal is a flat acrylic. Lugs are 19mm, which sets the bracelet vocabulary across every manual-wind Daytona. | The 6239 case is 36mm stainless steel, no crown guards, in the 3-6-9 chronograph idiom Rolex carried over from the 6238.

Its engraved tachymeter scale separates the 6239 from the 6238 at a glance, and the 275, 300, and 200-unit graduations place a given watch inside the run. | |||

Paul Newman wore the exotic-dial version Joanne Woodward gave him through his racing years, and its 2017 Phillips sale set the ceiling for the entire model. The dial itself — its Mk1 through Mk4 progression and the other host references — is covered on [[Reference:paul-newman-daytona]]. | |||
