Audemars Piguet 5134

The Audemars Piguet 5134 is an automatic extra-thin perpetual calendar with moonphase, introduced in 2015 and now discontinued. Based on the 2120 caliber, it features a peripheral rotor mounted on four ruby runners, maintaining the slim profile characteristic of the 51xx family. The moonphase complication remains accurate for 125 years without correction. As an in-house movement, it represents Audemars Piguet's vertical integration in manufacture calibers.
