Patek Philippe’s most complicated watch on sale at Sotheby’s 'Important Watches'

| No comment
Sotheby’s will be presenting the legendary Patek Philippe Yellow-Gold Calibre 89 for auction at the Important Watches sale in Geneva on 14 May 2017.


After 9 years of research and development, the Calibre 89 was unveiled by Patek Philippe in 1989 to mark their 150th anniversary.

Offered with an estimate of Swiss Francs 6.5–10 million, this horological masterpiece is one of the most important watches ever to be offered at auction, and it today, remains the brand’s most complicated watch ever created.


After setting a world record for any timepiece - US$ 24 million - with the sale of Patek Philippe’s Henry Graves Supercomplication  in 2014 (we wrote about it here), Sotheby’s is now going to offer another unique piece of exceptional importance.


The Calibre 89 has 33 complications, nine more than the Graves’ 24. Weighing 1100 grams (2lbs 6.4oz) and measuring 88.2 mm in diameter (with the case) and comprising 24 hands, 2 dials, 8 disks, 61 bridges, 129 jewels, 184 wheels, 332 screws, 415 pins and 429 mechanical components, the watch is comprised of an astonishing 1,728 parts. In addition to the complex calendar functions, including a tourbillon escapement and an astronomical sun hand, the watch features a unique calendar which displays the date of Easter every year.



This exceptional timepiece will be offered during the inaugural season at Sotheby’s brand new sales location in Mandarin Oriental, Geneva.
