Just in case anyone needs this information, as ive been trying to dig out and reference as much gen daytona photos i've observed:
6241, 6262 Paul Newman Pump Pushers goes with 271 end links and 7835 bracelet
6263 Paul Newman Screw Pushers goes with 371 end links and 7835 bracelet
6263, 6239, 6265 Big Red, regular daytona goes with 571 end links and 78350 bracelet
According to my friend who is a second hand gen watch dealer in Asia who has traded more than a dozen Paul Newman daytona's in the past decades, told me that some earlier Paul Newman's dial, case, endlinks and bracelet might had been replaced (upgraded) by Rolex when the watch is sent in for service. Some non oyster case daytonas will get a complimentary upgrade, and some earlier 271 and 7835 endlinks and bracelet set will be upgraded to later 571 and 78350.
