Auction introduction: Sotheby's is honored to present the Treasures of Time sale. Featuring some of the most desirable and sought-after timepieces on the market, this collection is nothing other than breathtaking. We are pleased to present a selection of some of Patek Philippe's most important references and some of its rarest timepieces. It is further highlighted by a collection of early and ultra-complicated Lange & Söhne alongside some elusive and ultra-rare Vacheron Constantin chronographs.
