Actually one of my friends had collected three of these: one from each of the three limited series of 50. And at a Tourbillon boutique event in San Francisco in February we had two of these Anniversary Editions in the room on the wrists of Bay Area collectors. But on the other hand, these truly are rare pieces (and absolutely lovely to boot!). One nice bit of news. When it comes time for service, the movement can be upgraded. The Anniversary Fifties use the Blancpain 1150 caliber. The 1150 is now free sprung, with inertial regulation and silicium spiral. That upgrade is really nice.
