One must always be wary and question these out-of-the-park prices at auction, they often aren't what they seem. You don't know who the winning bidder is (an individual, a consortium, an insider), was it partly underwritten by Patek Philippe (it's good advertising and they have a history of doing this), was financing provided by Christies to ensure a good price (that's been done, too)? There are lots of moving parts to these sorts of auctions and plenty of room for manipulation and other shenanigans. Perhaps it's a very wealthy individual that has that kind of money to spend on a watch for charity, or maybe not. But we will probably never find out the back story on this auction.
