During the 174 years since it was founded, Patek Philippe has demonstrated its expertise in the entire spectrum of horological complications. Impressive manifestations of this competence include the Calibre 89 presented in 1989. With 33 complications, it holds the world record as the most complicated portable mechanical watch. The Ref. 5002 Sky Moon Tourbillon is the manufacture's most complicated wristwatch with 12 complications on two dials. Now, with the Ref. 6002, the Sky Moon Tourbillon has a successor that redefines the term grand complication -- with a case and dial that require the utmost in craftsmanship and artistry.
