Audemars Piguet Royal Oak Perpetual Calendar

The Audemars Piguet Royal Oak Perpetual Calendar 26674ST is a modern icon of haute horlogerie. This 41 mm stainless steel model enters AP’s permanent collection and remains unworn, complete with box, papers, and certificate. Its integrated bracelet and dial set new standards in luxury sports watch design.

The case is crafted from brushed stainless steel, measuring 41 mm across and just 9.5 mm thick. It combines polished bevels with brushed surfaces and is water-resistant to 50 metres behind a glare-proof sapphire crystal and display caseback.

The bezel retains the Royal Oak’s signature octagonal shape with white gold screws, highlighted by AP’s impeccable finishing.

The dial is deep bleu “Grande Tapisserie,” tone-on-tone with its subdials and inner bezel. Applied 18ct white gold hour markers and Royal Oak hands glow with Super-LumiNova. The layout includes day, date, month, leap-year, astronomical moon phase—and even a week indicator.

The movement is AP’s new ultra-thin Calibre 7138. This automatic calibre is just 4.1 mm thick, houses 422 components and 41 jewels, and delivers around 55 hours of power reserve. It features a user-friendly, tool-free calendar adjustment via the crown.

The integrated stainless steel bracelet mirrors the case’s fine finishing and closes with an AP folding clasp. The bracelet flows fluidly from the case and brings real on-wrist elegance.

This Royal Oak Perpetual Calendar is impeccable. The case, dial, and bracelet show factory-level perfection. All stickers and accessories remain intact. Everything channels Audemars Piguet’s commitment to craftsmanship and technical excellence.

The 26674ST blends the full perpetual calendar complication with modern Royal Oak styling. It offers all complications—day, date, month, week, leap-year, and moonphase—in a slim, sporty package suited for every occasion.

Whether worn or curated, this model offers mechanical brilliance and collector appeal. It’s ready to occupy its place in the next great collection.
