Patek Philippe – The Caliber 89

There is no doubt the Calibre 89 is the most complex watch ever done including 33 complications and 1728 parts. Its complications include the date of Easter, sidereal time and a celestial chart with 2,800 stars. It was created in 1989 to celebrate the 150th anniversary. There are only four available in platinum, white gold, rose gold and yellow gold. The calibre 89 took 9 years to be developed.
