Patek Philippe Calatrava’s new day-date function switches in a blink

Perhaps the best-known of all its collections, Patek Philippe’s Calatrava has been a solid pillar of the brand since 1932.

The line’s clean, simple design was initially inspired by the Bauhaus movement, which emphasizes functionality and geometric shapes as part of its principles. Functionality, of course, is an important value for the watchmaker, whose mechanical movements boast extraordinary timekeeping performance.
