5. Patek Philippe 1939 Platinum World Time Watch

• Price: $4.1 million

One of Patek Philippe’s Time Collection pieces, only one unit of this Platinum World Time Watch was manufactured, way back in 1939. The watch is capable of showing the time in 42 different cities of the world, has a self-winding mechanism, and it doesn’t look too bad either. That’ll be $4.1 million,
