Audemars Piguet Code 11.59 RD#4 Universelle Introduction - HODINKEE

Among the 23 complications are a Grand Sonnerie Supersonnerie, minute repeater, perpetual calendar, split-seconds flyback chronograph, and flying tourbillon.

There are three pushers on the left side of the midcase: the first operates the minute repeater (with an engraved musical note to remind you of its symphonic purpose), while the bottom two correct the day and date.

AP developed a new double caseback system that comprises a "secret" extra-thin cover and a new soundboard that's just 0.6mm thick and crafted entirely of sapphire crystal, on which the gongs are mounted.

Then, the L'Universelle took its rightful place at the center of the Audemars Piguet Musée Atelier, where it's surrounded by eight of the brand's other most important grand complications.
