Labelking, To clarify, the cal. 89 pocket watch in 18kt yellow gold was sold by Antiquorum in Geneva on behalf of Patek for Sfr. 4,950,000 ($3,000,000) was the most expensive new Patek ever sold. I think the piece you are thinking of is the Graves Supercomplication, which was sold in 1999 by Sotheby's for the immense sum (for a pocket watch) of $11,003,500. Whilst, it is the most expensive portable timepiece ever sold, it does not hold the record for the most expensive timepiece sold, that title goes towards Vacheron. Jon.
Yes, I got confused. There were a few highly complicated pocket watches by Patek sold at various auctions for those figures. The Kallista is that diamond women's watch, yes? I have a penchat though, for the Ulysee Nardin Freak, and Genghis Khan.
