Audemars Piguet Introduces Royal Oak Perpetual Calendar in “Bleu Nuit, Nuage 50” Ceramic

Audemars Piguet unveils a striking new variation of the Royal Oak Selfwinding Perpetual Calendar 41 mm, combining technical innovation with refined aesthetics.

The model unites two breakthroughs launched in 2025: the signature “Bleu Nuit, Nuage 50” ceramic and the advanced Calibre 7138.

The movement features a patented all-in-one crown adjustment system, allowing the perpetual calendar to be set without tools and without risk of damage, an ergonomic innovation that enhances usability while preserving the mechanics.

The dial simplifies reading of the calendar indications while maintaining the Royal Oak’s signature Grande Tapisserie aesthetic, with blue counters and 18-carat white gold hands and markers.

The 41 mm case and bracelet are entirely crafted in “Bleu Nuit, Nuage 50” ceramic, a deep, historical hue from the Manufacture’s archives.

Polished and satin-brushed surfaces create a subtle interplay of light, highlighting the watch’s elegant silhouette while keeping it remarkably lightweight.

Calibre 7138 powers the watch with a 55-hour power reserve, 4 Hz frequency, and 423 components, all visible through the titanium and sapphire caseback.

Water-resistant to 50 metres, the timepiece blends technical mastery with Audemars Piguet’s signature hand-finishing, reflecting the brand’s pursuit of excellence.
