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.

The Calatrava collection has included a variety of complications and style options in its 90-plus years of existence, including diamond-set versions, perpetual calendars and minute repeaters. This year, a hand-wound movement joins the Calatrava lineup as an “everyday complication” in the new reference 5328G watch, according to the brand.
