Audemars Piguet – Royal Oak Perpetual Calendar “150th Anniversary” – Ref. 26605TI.GG.1224TI.01 – 2025

Celebrate a monumental chapter in horological history with the Audemars Piguet Royal Oak Perpetual Calendar “150th Anniversary”, an extraordinary timepiece that pays tribute to the brand’s pioneering legacy.

This exclusive limited edition of only 150 pieces is crafted in ultra-light titanium and incorporates a cutting-edge Bulk Metallic Glass (BMG) bezel—an innovative alloy known for its exceptional resistance and distinctive sheen. The 41mm case maintains the signature angularity of the Royal Oak, now enhanced by a textured “hammered” finish that adds bold visual contrast.

At its heart lies the final evolution of the revered Calibre 5135, showcased through an openworked dial inspired by the brand’s iconic perpetual calendar pocket watch Ref. 25729. The intricately skeletonized architecture reveals a stunning harmony between tradition and modernity, with subdials displaying day, date, month, and moonphase in perfect symmetry.

Paired with an integrated titanium bracelet and executed to the highest standards of finishing, this timepiece is not only a celebration of Audemars Piguet’s 150 years of innovation—but also a timeless investment in mechanical artistry.
