In 1995, Paul Newman participated in the 24 Hours of Daytona Race, where his team won first place in their GT-1 class. At the age of 70 years old, this made Newman the oldest man to win the race. Newman was gifted an incredibly special reference 16520 ‘Zenith’ Daytona to commemorate when he won the Man of the Year award presented at the 24 Hours of Daytona Race. Rolex was officially granted the sponsorship of the 24 Hours of Daytona race in 1991, and has held that title ever since. The watch bears the inscription ‘Rolex at Daytona 24 Paul Newman Rolex Motorsports Man of the Year 1995′, a title that Newman held proudly. The serial number S’498’728 dates the watch to 1993, which is consistent with other watches presented that year to other winners of Rolex 24
