This Rolex “RCO” Paul Newman Daytona reference 6263 has set a new world record for the most expensive Daytona ever sold at auction. All told, the watch sold for an atmospheric $1,089,186 USD when the bidding ceased at Christie’s auction last night. So what makes this watch so special? This “RCO” is believed to be the only authentic Daytona with a black Paul Newman dial and screw-down pushers. Perhaps its most distinguishing feature is that the dial reads “Rolex Cosmograph Oyster” instead of the traditional “Rolex Oyster Comograph.” This may seem like a minor detail, but to seasoned collectors, it clearly makes all the difference. Head over to Perpetuelle for a closer look at this rare — and expensive — watch.
