Overview

Platinum, 50 mm

The Audemars Piguet 150 Heritage Ultra-complication Universal Calendar, reference 75150PT.OO.01, a pocket watch in hand-engraved platinum, 50 mm across, with a blue grand feu enamel dial. Hand-wound Calibre 1150, with a Grande Sonnerie Supersonnerie, minute repeater, tourbillon and split-seconds chronograph, and a Universal Calendar in the caseback.

The Audemars Piguet 150 Heritage Ultra-complication Universal Calendar, reference 75150PT.OO.01, is a pocket watch rather than a wristwatch. Its platinum case is 50 mm across and 15.8 mm high, engraved entirely by hand with commemorative motifs and 150-year anniversary emblems, and closed by a glass box sapphire crystal and a Supersonnerie soundboard caseback. The dial is translucent blue grand feu enamel, hand-engraved with star trails, with hand-engraved 18-carat white gold Roman numerals, tone-on-tone counters with a silver grey-toned thread and 18-carat pink gold hands. It is carried on a hand-made platinum chain.

The movement is Calibre 1150, a hand-wound calibre giving a Grande Sonnerie Supersonnerie, minute repeater, tourbillon, flyback chronograph, split-seconds chronograph, astronomical moon, moon phases, large date, hours and minutes. It is 34.3 mm across and 8.9 mm high, built from 1,099 parts holding 81 jewels, and runs at 3 Hz (21,600 vph) with a power reserve of 60 hours. Housed in the caseback is the Universal Calendar, a lunisolar mechanism that Audemars Piguet describes as uniting solar, lunar and lunisolar cycles in one display.

For collectors

Audemars Piguet presents the 150 Heritage as a limited edition, limited to two platinum editions and eight white gold variations, and pairs Calibre 1150 with the Universal Calendar, hand-engraving, grand feu enamelling and a platinum chain.
