The tradition of creating pocket watches bearing astronomical indications dates back to the 16th century. Breathing life into those ideas, Patek Philippe manufactured the Sky Moon Tourbillon Reference 5002. The piece, created in 2006, features 686 parts presented in conjugation with 12 horological complications like the perpetual calendar, the tourbillion, sky chart, fly back, leap year cycle, orbit display and moon phases. Flaunting double dials, the wristwatch is said to be the first example of a white gold dialed watch displayed at an auction. Patek Philippe, insider sources reveal, manufactures only two of these spectacular pieces every year for its top notch clients.
