Housed in an 18-carat white gold case measuring 42mm, this Code 11.59 Supersonnerie is among the most complication-rich timepieces Audemars Piguet has ever produced. The NAC-treated white gold dial features grey counters, a black external zone, and white gold hands, while a sapphire crystal provides an unobstructed view of the movement architecture beneath. The black alligator strap is secured by an 18-carat white gold AP folding clasp, lending the ensemble a cohesive and refined character.
The self-winding mechanical movement spans 34.3mm in diameter and is set with 90 jewels, oscillating at 3 Hz (21,600 vph) with a 60-hour power reserve. Its function set is extraordinarily broad: Grande Sonnerie, minute repeater with Supersonnerie chiming, tourbillon, flyback chronograph, split-seconds, moon phase, and large date — all contained within a single caliber composed of 1,155 individual components.
This example is offered as a complete set with its original box and papers. Water resistance is rated to 20 meters. Reference 26398BC.OO.D002CR.02 stands as a serious collector's piece for those drawn to the intersection of sonic complexity and mechanical virtuosity at the very summit of contemporary horology.
