The dial displays a complete perpetual calendar, including:
- Day of the week
- Date
- Month
- Week of the year
- Leap year indicator

Despite offering multiple complications, the dial remains clean, balanced, and easy to read.
Audemars Piguet Calibre 5134 Automatic Movement

Powering the watch is the Audemars Piguet Calibre 5134, an ultra-thin self-winding mechanical movement developed specifically for the Royal Oak Perpetual Calendar collection.
The movement delivers approximately 40 hours of power reserve while maintaining exceptional accuracy and reliability.
Visible through the sapphire crystal caseback, the movement showcases beautifully finished bridges, decorative engraving, and the fine craftsmanship that defines Swiss haute horlogerie.
Advanced Perpetual Calendar Complication
The perpetual calendar automatically adjusts for different month lengths and leap years.

Built for Everyday Luxury
The Royal Oak Perpetual Calendar is fitted with an integrated black ceramic bracelet that provides both durability and exceptional comfort.
A titanium folding clasp offers a secure fit while maintaining the lightweight feel of the watch.
Scratch-resistant sapphire crystal protects both the dial and exhibition caseback, while 20 meters of water resistance provides protection during everyday wear.
