Called “The Titanium and Ruby Collection”, Christie's is presenting a landmark collection of the most valuable single-owner collection of Patek Philippe watches ever offered in Asia. With a total low estimate of US $12 million, the collection consists of models that come from different eras; vintage, modern and contemporary.

“Continuing our leadership in offering the finest Patek Philippe timepieces at auction in Asia, and off the back of our record-breaking sale of the Patek Philippe Ref. 2523 for HK$70,175,000 last Autumn, it is our utmost privilege to be presenting this legendary collection this year. We have no doubt that the sale will mark a monumental moment in auction history and will convene the world’s greatest collectors and connoisseurs.”commented Alexandre Bigler, Vice President and Head of Watches, Christie’s Asia Pacific.
