Audemars Piguet’s New Perpetual Calendars: Openworked Caliber 7139 & Blue Ceramic Royal Oak (2026)

Unveiling a Trio of Timeless Perpetual Calendars: Audemars Piguet's Latest Innovations

A true masterpiece of timekeeping, the perpetual calendar is a testament to precision and craftsmanship. Audemars Piguet, a brand renowned for its innovative spirit, has unveiled not one, but three new perpetual calendar watches, each with its own unique charm and story to tell. Let's dive into these captivating timepieces and explore the intricacies that make them stand out.

The Openworked Revolution: Caliber 7139

The star of the show is undoubtedly the new openworked Caliber 7139, which makes its debut in two stunning models: the Code 11.59 and the iconic Royal Oak. This movement is a masterpiece in itself, offering a complete adjustment of all indications via the crown, a significant upgrade from its predecessor.

The Code 11.59 Perpetual Calendar Openworked, with its reference number 26443NB.OO.D002CR.01, boasts a contrasting two-tone design in 18K white gold and black ceramic. The black ceramic midcase is sandwiched between the white gold bezel and caseback, creating a visually striking piece. The dial side continues this theme, with a sapphire dial, smoked elements, and a black inner bezel for the 52-week indication. The moonphase, set against black aventurine, adds a touch of elegance, while the subdial hands with red tips enhance legibility.

But here's where it gets controversial... The Royal Oak Perpetual Calendar Openworked, ref. 26685XT.OO.1320XT.01, encased in titanium and Bulk Metallic Glass (BMG), takes a different approach. While maintaining the subtle two-tone look with a fully polished BMG bezel, this Royal Oak adds a warm touch with pink gold surrounding the four registers and applied indices. The photorealistic moons on the moonphase are given a rosy hue, creating a unique and romantic ambiance.

And this is the part most people miss... Audemars Piguet has also released a non-openworked version of the Caliber 7138, showcasing its versatility. The Royal Oak Perpetual Calendar in "Bleu Nuit, Nuage 50" ceramic, ref. 26674CD.OO.1225CD.01, is a stunning example of the brand's updated shade of blue ceramic. With a matching blue grande tapisserie dial and inner bezel, it's a true blue lover's dream.

Pricing and Availability:

  • Code 11.59 Perpetual Calendar Openworked: CHF 118,000
  • Royal Oak Perpetual Calendar Openworked: CHF 180,300
  • Royal Oak Perpetual Calendar Blue Ceramic: CHF 133,900

All three models are available at AP boutiques and retailers, offering a unique opportunity to own a piece of horological excellence.

Our Take:

These three perpetual calendar models are a testament to Audemars Piguet's ability to create diverse and appealing timepieces. From the openworked wonders to the elegant blue ceramic edition, each watch tells a different story while expanding the brand's already impressive catalog.
