In a world of rare and expensive watches, you don’t earn the nickname “The Unicorn” without having some next-level scarcity to your name. That’s the case with this white gold Rolex Daytona, which is said to be the only of its kind in existence, as such Daytonas were only offered in standard gold and stainless steel previously. Owner and watch collector John Goldberger once said he would never sell the uber-rare watch, but he’s now changed his tune, saying he wants to sell the watch “to help those who were less fortunate.” More specifically, the watch will be auctioned off to benefit Children Action, a Swiss charitable foundation striving to provide for children in need of medical care, psychological support, and more. The case is in excellent shape and is paired with a white gold band that did not originally come with the watch. If you have insanely deep pockets and want one of the rarest watches on earth, this is your change to own one.
