Audemars Piguet Code 11.59 Gold/Ceramic — Skeleton Openwork Dial | Ref. 26397QA.OO.D002KB.01

Among the most technically audacious timepieces in Audemars Piguet's contemporary portfolio, the Code 11.59 Grande Sonnerie Carillon Supersonnerie in yellow gold and black ceramic represents a summit of acoustic and mechanical engineering. Introduced as a 2023 new release, the 41 mm round case features a black ceramic middle section flanked by 18-carat yellow gold lugs, bezel and caseback — an architecturally bold bi-material construction that encapsulates the Code 11.59's distinctly three-dimensional identity.

The skeleton openwork dial eliminates any visual barrier between the wearer and the extraordinary mechanism within, revealing a chiming calibre of exceptional complexity. Index hour-markers in black frame the movement architecture, while the transparent display allows full appreciation of the grand sonnerie striking train — capable of chiming the hours and quarter-hours with cathedral-quality resonance using the patented Supersonnerie system, which dramatically enhances acoustic volume and tonal purity. The AP folding clasp and double glareproofed sapphire crystal complete a case engineered to the highest standards.

At HKD 399,999, this example sits at the apex of the Code 11.59 collection and addresses the most sophisticated collector — one who understands that grand sonnerie complications remain among the rarest and most demanding achievements in haute horlogerie. Supplied complete with original box and papers, the 26397QA is an instrument as much as it is a timepiece, and an unmistakable statement of technical mastery.
