Introducing Audemars Piguet Unveils The 150th Anniversary Royal Oak Perpetual Calendar Openworked

Audemars Piguet Unveils Its New Releases for the First Half of 2025, Marking the Beginning of Its 150th Anniversary Celebrations with Ten New Models. The Most Significant Development Among Them Is the Introduction of an Entirely New Perpetual Calendar Movement: the Automatic Caliber 7138.

Alongside this new movement, the brand is discontinuing one of its most renowned calibers, the 5135, which has been in use for the past decade. Last year, the company also retired the 5134 caliber with the release of the "Perpetual Calendar" in collaboration with John Mayer, a movement that served as the foundation for Audemars Piguet’s openworked 5135 caliber.

This release, inspired by the brand’s classic designs, pays tribute to the 5135 caliber—one of the brand's iconic openworked perpetual calendar movements, while incorporating titanium and BMG (Bulk Metallic Glass) into the case and bracelet. Limited to just 150 pieces, this exclusive model combines Audemars Piguet’s heritage with its technological prowess and features special design elements to commemorate this historic occasion.

The "Audemars Piguet Royal Oak Perpetual Calendar Openworked" comes in the brand’s iconic case, measuring 41mm in diameter and 9.9mm in thickness. The bezel, caseback rim, and central links of the bracelet are crafted from BMG, a composite material containing over 50% palladium. Audemars Piguet first introduced BMG (Bulk Metallic Glass) in 2021 with a unique Royal Oak model created for the "Only Watch" charity auction.

The watch features a screw-down titanium crown and an anti-reflective sapphire crystal on both sides, ensuring a clear view of the openworked movement. The titanium case also provides water resistance up to 20 meters.

The sapphire dial takes inspiration from the reference 25729 pocket watch, created in 1992 and preserved in the "Atelier Audemars Piguet Museum." It showcases the openworked perpetual calendar movement, framed by a blue inner ring displaying the week numbers and complemented by subdials with blue surrounds.

The date indicator is positioned at 9 o’clock, while the moon phase display at 6 o’clock stands out as one of the most striking features. The subdial at 12 o’clock shows the months and leap years, while the day is displayed at 3 o’clock. All hands are blue and coated with white Super-LumiNova, except for the week hand, which is white. Both the hands and hour markers are crafted from white gold.

The transparent caseback reveals the automatic caliber 5135 in its final appearance, as the company has confirmed that this will be the last model to use this movement. The 5135 was previously featured in several iconic editions, most recently in a brown ceramic model created in collaboration with "Cactus Jack."

The movement’s finishing showcases a striking contrast between rhodium-toned components and rose gold accents. It operates at a frequency of 19,800 vibrations per hour and features an openworked 22-carat rose gold oscillating weight, adorned with the signature "Tapisserie" pattern and meticulously finished with satin brushing and beveled edges.

The "Audemars Piguet Royal Oak Perpetual Calendar Openworked 150th Anniversary Edition" is presented on a Royal Oak titanium bracelet with central links in BMG and secured with a three-blade folding clasp. This exclusive timepiece is limited to 150 pieces and is priced at 175,000 Swiss francs, approximately 718,880 AED.
