Patek Philippe 1939 Platinum World Time Watch – $4,026,524. Perhaps the only one created, the 1939 Platinum World Time watch sold for $4 million in a 2002 auction.
Louis Moinet Meteoris Watch – $4,599,487. When Moinet asked Luc Labenne to get pieces from a meteorite, asteroid and the moon, little did they know that they would be creating a watch now worth more than $4.5 million. This series came in a set of four tourbillion watches.
