This 37mm Royal Oak model showcases Audemars Piguet's dedication to refined aesthetics and technical excellence.

Design and Craftsmanship

The Royal Oak's signature octagonal bezel, secured with eight hexagonal screws, is rendered in stainless steel. The glareproofed sapphire crystal and caseback provide durability and a clear view of the dial. The "Bleu Nuit, Nuage 50" dial's "Grande Tapisserie" pattern adds depth and texture, while the luminescent coating on the white gold hands and hour markers ensures visibility in low-light conditions. The integrated stainless steel bracelet is secured with an AP folding clasp, providing both comfort and security.

Movement and Performance

At the heart of this timepiece lies the Audemars Piguet Calibre 5900, a selfwinding mechanical movement developed and manufactured in-house.

Its slim profile, at just 3.9 mm in thickness, contributes to the watch's sleek and comfortable wear.
