Notes

The ?Celestial Wristwatch" The ?Celestial? was introduced at the Basel Fair in 2002. Two years earlier, the ?Star Caliber 2000? had made headlines as one of the most complicated pocket watches ever produced, featuring exact configurations of the nocturnal skies with its star movements, moon position and progressing phases within the lunar cycle. This watch followed in the footsteps of earlier and famous supercomplicated Patek Philippe watches such as the ?Duke of Regla? (1909), the ?Graves Super- Complication? (1933) and the ?Calibre 89? (1989). In April 2001 Patek Philippe had unveiled the ?Sky Moon Tourbillon?, a ?Grand Complication? wristwatch capable of displaying celestial motions with incredible accuracy. Benefiting from Patek? s great experience in astronomy, mathematics and microengineering, the watch incorporated further miniaturized astronomical functions, combining them with a tourbillon regulator and a minute repeater with long circumference ?cathedral? gongs, which utilized a special steel alloy to surpass any other chime in a wristwatch. The ?Sky Moon? was the most complicated Patek Philippe wristwatch. The ?Celestial? wristwatch displays the night sky of the Northern Hemisphere by utilizing 3 superimposed sapphire disks, which rotate at different speeds in order to show the angular motions of the stars and the moon as well as the moon phase progressions. The disks are covered by the front sapphire crystal with its inner ellipse, framing the visible portion of the skies above Geneva and other cities sharing the same latitude. The rotation speed of each disk required a certain transmission ratio in order to assure the greatest accuracy of all astronomical indications.
