Audemars Piguet marks 150 years with a luminous Royal Oak Perpetual Calendar Openworked

To celebrate a century and a half of uncompromising artistry, Audemars Piguet unveils the Royal Oak Perpetual Calendar Openworked “150th Anniversary”, a limited edition that honours the Manufacture’s legacy while embracing the future of fine watchmaking.

This commemorative timepiece carries profound significance: it is the final model to be powered by the Calibre 5135, the movement that defined the openworked selfwinding perpetual calendar in a 41 mm Royal Oak case. In this farewell, the Maison bridges past and present, paying tribute to the calibre’s storied run with a creation designed to endure as a collector’s jewel.

The case and bracelet pair titanium with Bulk Metallic Glass (BMG) — an advanced alloy known for its extraordinary strength and lustrous sheen. This high-tech interplay of materials contrasts elegantly with the dial’s vintage-inspired aesthetic, a direct homage to a pocket watch preserved in the Musée Atelier Audemars Piguet. Subtle echoes of reference 25729 lend the timepiece a sense of heritage, while the skeletonised construction reveals the perpetual heartbeat within.

Limited to 150 pieces, the watch introduces anniversary-specific design codes that enhance its celebratory aura — refined yet powerful, contemporary yet steeped in tradition. With its union of daring materials, openworked artistry, and timeless calendar complication, the “150th Anniversary” edition is more than a milestone: it is Audemars Piguet’s tribute to history, vision, and the beauty of time itself.
