Patek Philippe has introduced the Calatrava skeleton watch in a new rose-gold version. The famous ultra-thin, self-winding caliber 240 movement, which celebrated its 40th anniversary in 2017, is completely skeletonised, decorated and engraved by hand; the engraving alone accounts for about 130 hours of work.
