Patek Philippe presents the Calatrava skeleton watch in a new rose-gold version. The famous ultra-thin self-winding caliber 240 movement, which celebrates its 40th anniversary in 2017, is completely skeletonized, decorated and engraved by hand; the engraving alone accounts for about 130 hours of work. For the first time, the winding rotor is decorated with the engraved logo of the Patek Philippe Seal. It pays tribute to the rare handcrafts that are painstakingly upheld by the manufacture.
