Yesterday, at the Geneva Watch Auction: Five, the Rolex reference 6062, aka the “Bao Dai,” broke the all-time record for a Rolex at auction.

According to Phillips, “Following an eight-minute bidding war, between ten bidders in the room and three on the telephone, the iconic Rolex Reference 6062, ‘Bao Dai’ sold for CHF 5,066,000 to a phone bidder.”

The Rolex Bao Dai is a triple calendar with moonphase in yellow gold and is one of only three known to exist with diamond markers.

Additionally, this example is the only one to feature the diamond markers at even hours. Increasing the collectibility of this one-of-a-kind Rolex timepiece even further – and inspiring its nickname – is the fact that it originally belonged to the last emperor of Vietnam, His Majesty Bao Dai.
