This unique steel version of the brand’s flagship megawatch is very likely the top lot of the upcoming charity auction in Geneva.
Launched in 2014 to mark the company’s 175th anniversary, the Grandmaster Chime features whooping 20 complications, including five acoustic functions, two of which were the patented global premie res: the preprogrammed striking alarm time and the date repeater. Needless to say, it’s extremely rare and never before seen in steel, so bearing in mind some auction results of the past years, we’d guess on November 9 this piece takes the central stage by storm.
The so-called salmon dial decorated with the guilloched hobnail pattern shows the current time and the time at the second time zone. A date subdial with moonphase indicator is located at 6 o’clock and the subsidiary alarm time dial is at 12 o'clock with the alarm indicator and the exclusive inscription ‘The Only One’. There are also a strike work isolator display and its power-reserve indicator, a day/night indicator of the second time zone, a crown position indication and a strike mode display, and a movement power-reserve indicator. The second dial is in ebony-black and comprises 4 subdials – 24-hour and minute, day of the week, date with leap-year cycle and month – and a four-digit year display in an aperture.
All this technical splendor is driving by the c aliber 300 GS AL 36-750 QIS FUS IRM – manually wound mechanical movement, installed inside the 47.7 mm steel case. The complications are regulated through four push-buttons and the 3-position winding crown. The estimate for the one-of-a-kind Patek Philippe Grandmaster Chime is CHF 2,500,000 – 3,000,000.
