Patek Philippe Calibre 89: crowning 150 years
Philippe Stern’s assignment to his staff was simple: “Build the world’s most complicated watch.” In the video, two of the experts involved in the project talk about the nine years of development and production work needed to debut the Calibre 89 right on time for Patek Philippe’s 150th anniversary. It was a successful venture: the timepiece with 33 complications and 1728 parts remained the most complicated portable mechanical watch for over 25 years.
