150 Heritage

Marking a century and a half of horological excellence, Audemars Piguet is pleased to unveil the 150 Heritage pocket watch – a creation that celebrates the history of humankind, bridging centuries of astronomical observation, technical mastery and craftsmanship. At its heart beats Calibre 1150, the new ultra-complicated movement that builds on the core architecture of Calibre 1000, with all activation mechanisms – such as crown-pushers and correctors – entirely reimagined to suit the compact pocket watch format and its intended use. This limited edition also introduces the Universal Calendar for the first time: a mechanical calculator visible from the caseback and independent of the movement, offering a panoramic view of the celestial cycles that have shaped cultural celebrations across the world. With 47 functions, including 30 complications*, the 150 Heritage harmoniously blends complications with intuitive operation, reflecting the brand’s commitment to putting ease of use at the centre of mechanical innovation. Showcasing an array of métiers d’art, this pocket watch is adorned with hand-engraved platinum, luminous ‘Grand Feu’ enamelling and a hand-made chain, each element celebrating the traditional crafts that characterise Haute Horlogerie. The first ultra-complicated watch truly designed to fit inside a pocket, it lays the foundation for a new horological concept that blends tradition, innovation and modern portability.

Housed in the pocket watch’s caseback cover, the Universal Calendar draws inspiration from humanity’s relationship with the sky. Unlike traditional perpetual calendars, which follow a single time system, this mechanism embraces the plurality of interpretations around the world. Its dial not only presents complex astronomical data but also offers an alternative way to experience time by blending horology with astronomy and tradition. the Universal Calendar itself compiles 8 complications which bring together solar, lunar and lunisolar cycles on a single dial for a 360° panorama counting 18 indications: the year, leap years, months, dates, weeks, moon phase and seasonal markers, such as solstices and equinoxes, and nine cultural celebrations drawn from global traditions. Some celebrations are based on the Sun – Christmas (Sol Invictus) and Saint John’s Day (Inti Raymi); some on the Moon – the beginning of Ramadan; and others are lunisolar, including Diwali, Rosh Hashanah, Pesach, Vesak, Easter and the Chinese New Year. Each event is shown as a consequence of an astronomical phenomenon, creating a strong connection between the cosmos and human tradition.

*These numbers may vary depending on sources and interpretation. Under the FH standard, the total may reach 60.
