The Patek Philippe reference 5575 is one of the manufacture's most extraordinary commemorative Grand Complication wristwatches, created to celebrate the 175th anniversary of Patek Philippe in 2014. Produced as a strictly limited edition, the 5575 combines the celebrated World Time complication with the spectacular Celestial display, powered by the automatic Calibre 240 HU LU. In addition to simultaneously displaying the time across all 24 time zones, the watch features rotating sapphire crystal discs that accurately depict the apparent motion of the stars, the orbit and phases of the moon, and the meridian passage of Sirius and the moon as viewed from the Northern Hemisphere.

Limited to just 1,300 examples in white gold, the reference 5575 is distinguished by its striking blue celestial dial, exceptional movement complexity and elegant 40mm case. Combining two of Patek Philippe's most iconic complications within a single timepiece, the 5575 has become one of the manufacture's most collectible modern limited editions, celebrated for its technical ingenuity, artistic execution and significance as the flagship wristwatch of the 175th Anniversary Collection.
