Movement

At the heart of this timepiece is the Audemars Piguet Caliber 5134, a self-winding mechanical movement developed and crafted in-house. This ultra-thin movement (only 4.31mm thick) is based on the legendary Caliber 2120 and has been re-engineered to accommodate the perpetual calendar’s full suite of astronomical indications.

Functions: Hours, minutes, day, date, month, leap year, week of the year, astronomical moon phase

Rotor: 22K gold oscillating weight, beautifully engraved and visible through the sapphire caseback

This movement automatically accounts for varying month lengths and leap years, requiring no manual adjustment until the year 2100. The astronomical moon phase is so precise that it will deviate by only one day every 122 years - a hallmark of Audemars Piguet’s horological excellence.
