Audemars Piguet Code 11.59 White Gold & Ceramic — Skeleton Grande Sonnerie Carillon Supersonnerie | Ref. 26397NB.OO.D002KB.01

At 399,999 USD, the 26397NB occupies the very summit of Audemars Piguet's manufacture ambitions — a watch whose extraordinary complexity positions it among the most technically significant timepieces produced at Le Brassus in the modern era. The Grande Sonnerie Carillon Supersonnerie complication represents centuries of acoustic engineering distilled into a single wrist instrument: striking the hours and quarter-hours in passing on cathedral gongs, with a petite sonnerie and minute repeater capability that transforms the Code 11.59 case into a concert hall of horological music.

The skeleton dial — one of the most dramatically arresting in the current Audemars Piguet catalogue — lays bare the Grande Sonnerie's remarkable movement architecture, the openworked bridges and plates revealing a mechanical landscape of precision-cut components in extraordinary relief. Black hands trace their path across this open stage with authoritative legibility, while index hour-markers on the chapter ring provide temporal reference without obscuring the view within. The movement is decorated to the highest standards of finish achievable in contemporary horology, each component hand-bevelled, polished, and assembled by a specialist watchmaker.

The 41 mm case pairs a black ceramic middle section with 18-carat white gold lugs, bezel, and caseback — a combination that creates chromatic tension between industrial hardness and precious metal warmth, directly mirroring the sonic tension between the Grande Sonnerie's commanding strike and the whispered precision of its individual gong vibrations. The 2023 new release designation marks this as a current-generation piece, available with full box and papers, bearing the Supersonnerie acoustic innovation that represents Audemars Piguet's most significant contribution to repeating-watch engineering since the house's 19th-century founding. An appointment-only acquisition for the most committed collector.
