What type of watch did Ryan Gosling wear in the movie Drive?

In the movie Drive (released on 9/16/2011) Ryan Gosling is wearing a Patek Philippe with a brown leather strap, however it's not something you can just go and buy, it's not a real model of the watch. Prop master Will Blount told GQ.com that the watch needed to be iconic and memorable, so they couldn't just take something off the shelf. Someone who may have seen the watch in person is Eva Mendes who is rumored to be vacationing in Thailand with Gosling, one of the few people to have a copy of the watch.
