Audemars Piguet 150 Heritage Pocket Watch
Audemars Piguet debuts the 150 Heritage pocket watch for its 150th anniversary, limited to two platinum pieces and eight planned in white gold. The 50mm hand-engraved platinum case houses Caliber 1150 with 40 functions, including 22 complications, among them a minute repeater, Grande Sonnerie, split-seconds chronograph, flying tourbillon, and perpetual calendar. The blue grand feu enamel dial displays time and calendar functions, while the hinged caseback reveals the Universal Calendar, a mechanical system tracking solar, lunar, and lunisolar cycles. It displays religious holidays like Easter, Ramadan, Chinese New Year, and Diwali alongside solstices and moon phases. The design draws from AP's 1899 L'Universelle and 1921 Grosse Pièce pocket watches and includes a handmade platinum chain.
