Since 2015, Audemars Piguet has advanced haute horlogerie with a series of innovations, starting with the Supersonnerie technology (RD#1). An ultra-thin perpetual calendar movement (RD#2) followed in 2018, and an oscillator with increased amplitude (RD#3) was unveiled last year.
The Le Brassus-based watchmaker had bigger plans than a trilogy. The three ingenious mechanisms are incorporated into RD#4 or Code 11.59 by Audemars Piguet Universelle, which pays tribute to a pocket watch with 26 functions and 19 complications from 1899.
