Patek Philippe Pushes Boundaries With Its Perpetual Calendar Timepieces

Patek Philippe Pushes Boundaries With Its Perpetual Calendar Timepieces

A private complication.

No other watchmaker is more closely linked with the perpetual calendar than Patek Philippe, an association that goes all the way back to 1925, when it created the first perpetual calendar wristwatch. In a trailblazing run since, the brand introduced the retrograde perpetual calendar wristwatch (1937), perpetual calendar chronograph (1941), sweep seconds perpetual calendar wristwatch (1944) and self-winding perpetual calendar (1962), each time setting new benchmarks for the mastery of this grand complication.
