Patek Philippe's Most Complicated Watch Ever

May 02, 23 by John Jeffay

(IDEX Online) - Patek Philippe says it has created the most complicated watch in its 184-year history.

The latest version of its Grandmaster Chime - a reversable watch with two faces and a patented swivel mechanism - has 20 complications and a $2.2m price tag.

The white and rose gold timepiece has an ultra-complicated manually wound mechanical movement.

"Among the 20 complications are five acoustic functions, including two patented world exclusives: an alarm sounding the programmed time and a date-repeater striking the date on demand," says the Swiss watchmaker. (full list of complications below).

The watch, Ref 6300GR-001, is the newest iteration of the Grandmaster Chime, launched in 2014 and comes with a pair of matching gold cufflinks.

In 2019 a one-off Grandmaster Chime Ref. 6300A - at the time Patek Philippe's most complicated watch - broke the world record when it sold for $31m at a charity auction.

The new Grandmaster Chime Ref 6300GR-001 specification lists: "Grande and petite sonnerie. Minute repeater with classic gongs. Strikework mode display (S G P). Alarm with time strike. Alarm on/off indication. Date repeater. 

"Movement and strikework power-reserve indication. Strikework isolator indication. Second time-zone. Second time zone day/night indication. Instantaneous perpetual calendar. Day, date (on both dials), month, leap-year cycle by hands. Four-digit year display in an aperture. Moon phases. 24-hour and minutes subdial. Crown position indication (R A H)."
