The Complete Buying Guide to the Rolex Daytona

Daytona: Added to the dials along with "Cosmograph" in the early 60s just after Rolex became the official timekeeper at the Daytona Florida raceway Big Red: Some collectors refer to models with the large red "Daytona" over the 6-o'clock subdial as "Big Red." A dial with red on it is not necessarily a Paul Newman dial Musketeer Dial: After Rolex took the red away from the Daytona in the early 1970s, they quickly reintroduced it.

A Sigma dial can add value to an otherwise standard production-run Daytona or other Rolex Simply named Rolex Chronograph, the 6238 both featured neither "Cosmograph" nor "Daytona" on the dial Standard dial variant typically sees "Daytona" under "Cosmograph"; rarest version features only Rolex signature without "Oyster Cosmograph"-Paul Newman dial remains the same as 6239 or can have "Daytona" under "Cosmograph" on some examples.

Notable Visual Changes:-Sub-Dial Lift: Though the watch didn't change much stylistically with the new movement, one can easily make out a 4130-loaded Daytona because the two sub-dials are slightly raised above the equator of the dial. . Source
