To mark a century and a half of uninterrupted watchmaking, Audemars Piguet unveils the 150 Heritage pocket watch, a creation that bridges astronomy, craftsmanship, and mechanical mastery. Conceived as a tribute to humanity’s enduring relationship with time, the piece looks both backward and forward, honouring ancestral savoir-faire while inaugurating a new horological concept. It is an object of contemplation as much as calculation.
At its core beats Calibre 1150, a new ultra-complicated hand-wound movement derived from the architecture of Calibre 1000. Far more than an adaptation, it has been reengineered to suit the proportions and tactile demands of a pocket watch. With 1,099 components and 47 functions, including 30 complications, it demonstrates how complexity can coexist with intuitive operation.

Grande Sonnerie, minute repeater, flying tourbillon, semi-Gregorian perpetual calendar, and split-seconds flyback chronograph coexist within a construction designed for ergonomic clarity. The integration of Supersonnerie technology enhances acoustic resonance, while the reimagined activation systems blur the boundary between case and movement. Crown-pushers and correctors are precisely positioned to ensure comfort, safety, and visual harmony.
The introduction of the Universal Calendar marks a conceptual breakthrough. Visible within the caseback, this independent mechanical system gathers solar, lunar, and lunisolar cycles into a panoramic display. Cultural celebrations and celestial markers unfold across a 360-degree tableau, linking solstices, equinoxes, moon phases, and global traditions within a single coherent mechanism.



Operation remains tactile and immediate. A bidirectional wheel adjusts up to two centuries of calendrical cycles, synchronised independently of the movement’s power reserve. It is a mechanical meditation on humanity’s shared observation of the skies, evoking the ancient civilisations that first divided time through sun and moon.
Beyond its technical achievement, the 150 Heritage stands as a showcase of métiers d’art. The platinum case is entirely hand-engraved, its surfaces transformed into a canvas for commemorative motifs and portraits of the founders. Grand Feu enamel, star trail engravings, and hand-crafted Roman numerals illuminate the dial with celestial depth, while a hand-made platinum chain completes the piece with quiet grandeur.

Limited to two unique platinum editions, the 150 Heritage does more than commemorate an anniversary. It affirms a philosophy where complexity serves clarity and tradition fuels innovation. Rooted in 150 years of expertise, this pocket watch embodies not only the measurement of time, but the human ingenuity that made it visible.
