Has anyone ever played with the Star Chrono GMT Perpetual Calendar

 Even more interesting would be if anyone has actually seen the one of three specimens produced in platinum.

Cheers,  Mike

Hi all, Have asked the MB Boutique where to find a MB star chrono gmt perpetual. As it was released in 2006, only one YG example was auctioned in 2007 and I assumed that all pieces are already sold out long ago (limited edition). To my surprise, the MB bo...
