Probably all know the Rolex Salviati paperweight made for Baselworld 2006. There is another version more rare of this Salviati Twinlock crown (two dots), which is the Triplock crown (three dots) that was made for opening of the new Rolex musem "The Rolex Experience" in Shanghai, 2011. On the back doesn't have the "Salviati, Made In Italy" sticker, but has the new Rolex wave pattern that you can find on many modern Rolex accessories.
I've made a few photos of both paperweights, i hope you'll like. As you can see the Baselworld 2006 Twinlock crown version it's a little bit smaller. More pictures you'll find on my account.
