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.
