or "Paul Newman" dial. It is said that Newman wore one of these watches, given to him by his wife Joanne Woodward when he took up automobile racing, from 1972. While other sources agree it was a gift from Woodward, they assert the watch was presented to Newman earlier, during the filming of Winning in 1968 or 1969. It is estimated that only one in twenty Daytonas were equipped with the "exotic" dial because they were slow to sell, and that only 2,000 to 3,000 such "exotic" dial variants were ever manufactured. Its distinguishing features are subtle. First, a Paul Newman dial must be in an original series watch (with a four-digit Reference number), installed by Rolex Geneva as original. All of the original series had acrylic domed crystals. In addition, the sub-dials of a "Paul Newman" Daytona have block markers instead of plain lines, have crosshairs across each sub-dial meeting at the centre, and the seconds sub-dial (placed at 9:00) is marked at the 15, 30, 45 and 60 positions, whereas a normal Daytona seconds sub-dial is marked at 20, 40 and 60. The dial may or may not have the word "Daytona" written on the dial above the hour sub-dial located at 6:00. The dial came in four color and layout combinations, and was installed as an option by Rolex on the Daytona line of watches in the original series. The watch went out of production in the early 1970s, and Rolex does not supply any replacement version of it. The outer track of the main dial is finished in a contrasting color that matches the color of the sub-dials. The typeface used on the sub-dials is different as well. Since the dials were made by Singer for Rolex, there are contemporary watches from other manufacturers which feature the same "exotic" dial. The earliest "Paul Newman" Daytonas are Reference 6239 model watches, which use a black or white dial, and are known as three-color watches, as they have the name "Daytona" and hashmarks on the outer track painted in red. They were succeeded by the Reference 6241 watches, which replaced the engraved stainless steel bezel with a black acrylic bezel. References 6262 (steel bezel) and 6264 (black bezel) were the last of the three-color watches as Rolex began to transition to Calibre 727, and the final References 6265 (steel bezel) and 6263 (black bezel) used a two-color dial
