Patek Philippe’s Grandmaster Chime crowns 175th anniversary celebrations

The most complicated wristwatch created by Patek Philippe and one of the world’s most elaborate wristwatches, the Grandmaster Chime features not only exceptional horological degrees of complexity but also two complication innovations, from the total of 20 complications which it features. The Grandmaster Chime is the first double-face timepiece by Patek Philippe which can be worn with either dial facing up. The current time and the date are displayed on both dials.

To protect complicated timepieces against damage caused by inadvertent manipulations, the Patek’s craftsmen conceived sensible isolators that interrupt the flow of power between individual mechanisms or block certain functions while others are active.

The Patek Philippe Grandmaster Chime in brief:

- more than 100,000 hours were logged for development, production, and assembly, of which 60,000 hours for the components of the movement

- each caliber consists of 1,366 parts and each case of 214 separate parts, bringing the total number of components for each timepiece to 1,580.

- 11,060 hand-finished parts

- only seven pieces created – six of them will be sold to long-standing collectors of Patek Philippe timepieces

- the seventh Grandmaster Chime will be on display at the Patek Philippe Museum in Geneva
