10. 1950 Rolex Perpetual “Sleeping Beauty”

Sold for $1.14 million in 2013

Ranking 10th on this list is the 1950 Rolex Perpetual “Sleeping Beauty.” Pieced together seven decades ago, this limited edition watch is intricately built with a beautiful moon phase and triple date display. It was originally nicknamed “Pandellone” in Italian, which literally translates to “Big Frying Pan.” Perhaps, the name had to do with the watch’s complex features.

Only 100 pieces of the masterfully crafted 1950 Rolex Perpetual were ever made. Finding one of these pieces in good condition is going to take some solid luck and serious search. How many of these watches are still in existence? No one knows for sure. But one this is certain – this timepiece broke the records as the most expensive Rolex to be sold in 2013 when it showed up at the auction block.

The initial estimate for this rare Rolex was in the vicinity of only $250,000 to $350,000. Bids from four people cutting across four different countries were steep, and the competition was fierce. But since surprises are the norm at auctions, Christie’s New York auction witnessed one of the most surprising bids ever, with a bid several times the estimated price.
