The Audemars Piguet Royal Oak Perpetual Calendar “150th Anniversary” is reference 26585XT.OO.1220XT.01, a 150-piece limited edition with a titanium and Bulk Metallic Glass (BMG) case and bracelet. Its openworked perpetual-calendar movement, Calibre 5135, is presented by the brand as a tribute to the calibre’s history. Audemars Piguet’s product page does not provide a usable current price or live availability figure, so buyers should confirm those details directly.

What is the Audemars Piguet 150th anniversary Royal Oak perpetual calendar?

It is a limited-edition Royal Oak Perpetual Calendar created for Audemars Piguet’s 150th anniversary. The official reference is 26585XT.OO.1220XT.01. Audemars Piguet describes the watch as vintage-inspired and identifies its special anniversary design codes alongside an openworked perpetual-calendar movement.

The anniversary is the company’s: Audemars Piguet dates its beginnings in Le Brassus to 1875. The Royal Oak arrived later, debuting in 1972; the brand credits Gérald Genta with its design. Audemars Piguet says the collection has since grown to more than 500 iterations. These dates and collection figures are the manufacturer’s account, detailed in its 150th-anniversary history and Royal Oak collection overview.

How many were made, and what are the case and bracelet made of?

Audemars Piguet states that the edition is limited to 150 pieces. The case and bracelet combine titanium and BMG, or Bulk Metallic Glass. The product page does not provide a usable price or current stock status in the information available there. See the brand’s official product page for the watch’s current listing and boutique-finder route.

What movement is in the Royal Oak 150th anniversary watch?

The watch uses Calibre 5135, which Audemars Piguet identifies as an openworked perpetual-calendar movement. The company calls this watch a final tribute to the historic calibre. Its anniversary history also discusses openworked Calibre 5135 in connection with the 2023 Royal Oak Perpetual Calendar “Cactus Jack”; that context does not establish that the two watches share identical specifications.

The available product information does not provide a complete technical specification sheet. Dimensions, power reserve, water resistance and additional movement details should therefore be checked against a current official specification rather than inferred from another Royal Oak or another Calibre 5135 watch.

How much does it cost, and is it available?

Audemars Piguet’s product page does not show a usable retail price or live availability figure in the available listing. No reliable current resale price or market-demand figure is established here either. Contact an Audemars Piguet boutique or authorized seller to ask about regional retail access; treat secondary-market listings as separate from authorized retail, and verify the seller, watch documentation and condition independently.

The brand’s product page provides a boutique finder and a service pathway, while its Royal Oak collection page directs owners to boutiques for servicing. Neither resource establishes a particular service price, turnaround time, warranty status or regional inventory.
