Patek Philippe unveiled its 175th anniversary collection which includes the Grandmaster Chime ref. 5175, the world’s most complicated wristwatch ever! It fuses classic chiming complications like the grande and petite sonnerie with brand new ones like the date repeater, while also building in a state-of-the-art perpetual calendar. There are only 7 units of this limited edition timepiece available with one residing in the Patek Philippe Museum in Geneva. The other six are priced at $2.6 million a piece. Let’s take a look at its specifications.
Just looking at the Grandmaster Chime, you feel you’re staring at something exquisite. The 18K rose gold case is absolutely massive at 47.4mm across and 16.1mm thick, and it is hand-engraved on nearly every surface. The case actually spins between the massive lugs, allowing you to see the two dials and a dial that shows the date of Easter.
Some of the specifications are-
- Grande Sonnerie
- Petite Sonnerie
- Minute repeater
- Strikework mode display
- Alarm with time strike
- Date repeater
- Movement power-reserve indicator
- Strikework power-reserve indicator
- Second time zone
- Strikework isolator display
- Second time zone day/night indicator
- Instantaneous perpetual calendar
- Day-of-week display
- Month display
- Date display (on both dials)
- Leap year cycle
- Four-digit year display
- 24-hour and minute subdial
- Moon phase
- Crown position indicator
The two dials are roughly divided between the time-telling side on the front and the calendar side on the back. The front has the alarm setting dial up top and the date and moonphase down at 6 o’clock. On the left is the power reserve for the movement, and on the right the power reserve for the sonnerie. Turning the watch over, you have (moving clockwise from 12 o’clock) the second timezone display, the month, the date and leap year cycle, the day of the week, and, in the center, the year.
So, there you have it! The most complicated and extravagant wristwatch ever.
