The most expensive watches in the world and everything you need to know about it

The wrist watch above, though it seems to be simple and not to have anything special - beyond the price! -, is made in 18 carat gold, its hands are silver, the gold numbers, the internal mechanism has 23 jewels, and it brings a perpetual calendar and up display to the phases of the moon. The piece belonged to the Stern family, owner of a luxury watchmaker Patek Philippe, and despite being valued between $ 1.4 million and $ 2.3 million, the watch was bought at a $ 5, 7 million in 2010.
