Christie's watch department succeeded in gathering 100 ancient Patek Philippe. All are going to be sold on Sunday and the battles among collectors should be as epic as memorable. Indeed, many unique and rare models are on sale such as a split-seconds chronograph bought by William E. Boeing in 1939 in Cartier, New York. The hours' hand shows indeed 3 red marks that evoke a ancien propeller, in addition to the fact that it is, of course, a magnificent piece! The Ref.1518 is the perpetual calendar with chronograph that belonged to King Farouk. And the pink gold chronograph perpetual calendar with moon phases Ref.2499 is estimated between 1,6 and 2,6 millions swiss francs. So no need to say that this sale will be a milestone in the history of watches auctions. John Reardon, Senior Vice President and International Head of Christie's Watch Department tells us more about this short-lived collection.
