Audemars Piguet Jules Audemars Grande Sonnerie Carillon Platinum — Black Index Dial | Ref. 26344PT.OO.D002CR.02

Among the most demanding acoustic complications in haute horlogerie, the Grande Sonnerie strikes the hours and quarters on the passage of each interval without manual activation — a feat requiring a movement of extraordinary mechanical complexity and impeccable regulation. This 39 mm Jules Audemars Grande Sonnerie Carillon in 950 platinum represents the very pinnacle of Audemars Piguet's manufacture capabilities, executed in one of the most prestigious metals available to the watchmaker.

Calibre 3090 beats within, hand-wound and painstakingly assembled by a small team of specialist watchmakers in Le Brassus. The carillon complication extends the chiming sequence across three gongs tuned to distinct pitches, producing a resonant melody that distinguishes this watch from simpler striking watches. The solid platinum case back keeps the acoustic chamber sealed for optimal sound projection, while a matte black dial with applied index hour markers and luminous hands ensures legibility without distracting from the watch's primary purpose as an acoustic instrument.

Mounted on a fine leather strap and offered at a price commensurate with its rarity, Ref. 26344PT.OO.D002CR.02 is a commission-level timepiece aimed squarely at the most serious horological collector. The combination of grande sonnerie, carillon chiming, and platinum construction in a 39 mm dress-watch profile makes this one of the most technically ambitious and collectible references in the entire Jules Audemars catalogue.
