This is the latest masterpiece by Hublot.
The Laferrari boasts 5 barrels providing 50 days of powerreserve, and I am assuming that this has to be a world record for a mechanical timepiece. I do not know of any other timepiece which has 50 days powerreservice.
This watch is limited to 50 pieces worldwide, and due to its price of appx. 300000 Swiss Franks, I am assuming it will be rare to see in the world. Nevertheless, this shows the true capabilities of the Hublot Manufacture showing that they can master a highly complicated and innovative wristwatch.
