Audemars Piguet Jules Audemars Grande Sonnerie Carillon Platinum — Slate Guilloché Dial | Ref. 26344PT.OO.D002CR.03

The Grande Sonnerie Carillon stands among the rarest and most demanding complications in all of watchmaking — a mechanism that chimes the hours, quarter-hours, and minutes on a carillon of gongs, demanding years of a master watchmaker's life to perfect. Reference 26344PT.OO.D002CR.03 embodies this tradition in its purest form: a 39 mm platinum case of classical round dress-watch proportions, its solid caseback sealing a manually-wound movement of staggering technical depth. The Jules Audemars collection was created explicitly to honour the craftsmen who shaped AP's early history, and no complication more fittingly carries that name.

Calibre 3090, AP's in-house grande sonnerie movement, animates this platinum dress watch. The mechanism provides both grande sonnerie — continuous automatic chiming of the time — and petite sonnerie, along with minute repeater function for on-demand auditory time-telling. The slate grey dial, dressed with luminous index markers and gold-toned hands, projects an austere elegance entirely consistent with the complication's gravity. A screw-down crown and leather strap complete an ensemble conceived for the evening and the boardroom alike.

Platinum's rarity as a case material is fitting here: the Grande Sonnerie Carillon is itself produced in vanishingly small numbers each year, making every example a significant secondary-market acquisition. Collectors of minute repeaters and chiming complications regard AP's sonnerie references as benchmark pieces — not merely technically accomplished, but sonically extraordinary. This is a watch one does not simply wear; it is a watch one listens to.
