Patek Philippe’s 175th anniversary is celebrated with the creation of limited-edition commemorative pieces. The star of the collection is the Patek Philippe Grandmaster Chime, a wristwatch with 20 complications. This pièce de resistance is accompanied by three further limited-edition commemorative timepieces for men and ladies that recall legendary models and technologies from Patek Philippe's heritage: the World Time watches with their patented time-zone mechanisms, the highly precise moon-phase display, the jumping indications, and the chronograph.
