After Girard-Perregaux gave the world amazing watches like the Opera one and the Opera Three (which is touted to be on of the most expensive watches) they have now come up with a new variant of the Opera three. This one comes in a small music box with a keyboard with 20 blades, which can be played through a spinning drum with 150 hand-mounted pins. That means that every time the watch completes an hour, the watch will play Tchaikovsky or Mozart instead of annoying beeps. A collector’s item, the watch saw first light in 2002 and comes with a platinum case and alligator skin strap. It was last priced at $532,000, making it the third most expensive watch in the world!
