With the Audemars Piguet 20th Century Complicated Wristwatches book as our map, Michael Friedman, Head of Complications at Audemars Piguet and previously the brand historian, brings Revolution through the rich lineage of the maison’s perpetual calendars. Starting from the reference 5516 to incredible revelations about the 5548.

The Audemars Piguet 20th Century Complicated Wristwatches is a brilliant collector’s handbook. Developed and produced by the brand’s own in-house team of researchers, the book catalogs the 550 complicated wristwatches that the maison produced through the 20th century and before the rebirth of complications for the brand in 1970, and much, much more.
