Patek Philippe Sky Moon Tourbillon, Ref. 5002
The rarest complications united in a wristwatch
On October 5, 2000, Patek Philippe unveiled the Star Calibre 2000, one of the most complicated pocket watches of all times. Barely six months later, the Geneva workshops are introducing a new Grand Complication - now in a wristwatch format. The "Sky Moon Tourbillon" Ref. 5002 is the most complicated wristwatch ever built by Patek Philippe, and it is the first double-faced wristwatch that features a complete presentation of the nocturnal sky on its reverse side. The new masterpiece displays the apparent movements of the stars, the orbit of the moon, the moon phases, as well as the hours and minutes in sidereal time.
A symphony of the most beautiful complications
As was already the case with the Star Caliber 2000, Patek Philippe's goal in the development of the "Sky Moon Tourbillon" was not so much the number of complications per se. The real objective was to accommodate the most fascinating complications in the small case of a wristwatch: a perpetual calendar with a retrograde date display, a minute repeater, a tourbillon, the display of sidereal time, and a depiction of the nocturnal sky with the motion of the stars, the orbit of the moon, and the moon phases. This turned out to be a formidable challenge because a chart of the heavenly canopy (as seen in the northern or southern hemisphere) requires a certain minimum space to demonstrate the movements of the stars in a sensible and clearly legible manner. The solution adopted by Patek Philippe was borrowed from the astronomical pocket watches made by the company: a moving sky chart on the reverse side of the timepiece. The mechanical module developed by Patek Philippe for the "Star Calibre 2000" was redesigned especially for the "Sky Moon Tourbillon" and was granted Swiss patent CH 688 171 B5.
