The Patek Philippe Grandmaster Chime


Last week, during Patek Philippe’s 175th celebration in Geneva, the prestigious watchmaker launched 10 new references. The highlight was the Grandmaster Chime Ref. 5175. Watch the video to truly appreciate what went into this unprecedented, horological work of art.


The Grandmaster Chime features rotating lugs to switch between the two dials and is presented in an 18K rose gold case measuring 47.4 mm by 16.1mm. The case is made up of 214 components and the entire exterior is decorated with intricate engravings, that were completely done by hand. The movement itself, caliber 300 GS AL 36-750 QIS FUS IRM, measures a whopping 37 mm by 10.7 mm, and consists of 1366 components, including 4 main spring barrels. It took 7 years to develop, 2 years to produce and is the source of six patents. And, with 20 complications in total, this is the most complicated timepiece Patek Philippe has ever produced.
