To celebrate of Patek Philippe 10-floor manufacturing facility in Plan-les-Ouates, and in typical Patek Philippe style, the brand unveils a special limited edition watch: Ref. 6007 Calatrava. The new commemorative piece is aptly built in stainless steel – reflecting the steel used in the new building. Because Patek Philippe rarely crafts watches in steel, that fact alone will make this piece in very high demand. Additionally, the 40mm watch boasts an exclusive design concept and just 1,000 pieces will be made.
