Calibre 2120/2802 was developed as the successor to Calibre 2120/2800, a movement that marked a significant milestone in the history of Audemars Piguet’s perpetual calendar wristwatches.
The addition of the leap year indication made it easier to set the calendar, allowing the wearer to synchronise the mechanism with the leap year cycle more intuitively.
From its inception, the calibre was produced in two distinct versions: classic and openworked. Openworked was was done in the traditional way, using a fine saw known as a boc-fil. A single movement required approximately one month of meticulous craftsmanship by a highly skilled artisan.
Remained in the catalogue for almost 20 years, this calibre powered various Royal Oak models as well as pieces from other collections, including the Jules Audemars line. It was ultimately succeeded in 2015 by Calibre 5134.
