Audemars Piguet is proving that the art of the pocket watch is far from a relic of the past. To celebrate its monumental 150th anniversary, the legendary Swiss manufacturer has unveiled Audemars Piguet’s 50 mm 150 Heritage Ultra-complication Universal Calendar Ref. 75150PT.OO.01 pocket watch, an awe-inspiring modern marvel of micro-mechanical engineering. Reconnecting haute horlogerie with humanity’s ancient dialogue with the cosmos, the new ultra-complicated pocket watch seamlessly bridges history, astronomy, and cutting-edge mechanical innovation in a breathtaking package.

Serving as the third pillar in the brand’s prestigious lineage of ultra-complicated pocket watches—following the L’Universelle in 1899 and La Grosse Pièce in 1921—the 150 Heritage is a masterclass in both scale and ergonomics. At the heart of the timepiece beats the newly developed Calibre 1150 manual-wind movement. Packing over 1,099 components, the mechanism orchestrates a staggering 47 functions and 30 distinct complications. The dense, masterfully crafted architecture integrates a Grande and Petite Sonnerie with Supersonnerie acoustics, a minute repeater, a flying tourbillon, a split-seconds flyback chronograph, and a semi-Gregorian perpetual calendar.

Despite its immense mechanical complexity, the pocket watch was designed to be highly intuitive and functionally tactile in the hand. Rather than an oversized, unwearable showpiece, the 23.4mm-thick case fits comfortably in the palm, utilizing carefully positioned pushers and concealed correctors to ensure every physical interaction feels deliberate and easy to navigate.

Visually, the timepiece is just as striking as its internal mechanics. The case is fully hand-engraved with commemorative motifs honoring the brand’s founders, framing an 18-carat white gold main dial finished in a translucent blue grand feu enamel with floating Roman numerals. However, the watch’s most groundbreaking feature hides under a secret push-piece caseback: a first-of-its-kind “Universal Calendar.” The mechanical calculator goes far beyond tracking standard dates, simultaneously mapping solar, lunar, and lunisolar cycles to display solstices, equinoxes, and nine major global cultural celebrations—including Ramadan, Diwali, Easter, Pesach, and the Chinese New Year.

Blurring the line between luxury accessory and museum-grade artifact, the Audemars Piguet 150 Heritage Ultra-complication Universal Calendar Ref. 75150PT.OO.01 pocket watch is reserved for the absolute upper echelon of horology collectors. The masterpiece will be produced in a highly exclusive run, limited to just two unique pieces in platinum alongside eight in white gold.
