Audemars Piguet Royal Oak Minute Repeater Supersonnerie Titanium — Salmon Grande Tapisserie Dial | Ref. 26591TI.OO.1252TI.02

Among the most acoustically sophisticated watches ever created, the Royal Oak Minute Repeater Supersonnerie represents a decade-long research programme by AP's acoustic engineers and master watchmakers into the science of sound transmission within a wristwatch. Traditional repeaters suffer from the case absorbing energy before the gong's vibration reaches the listener; AP's patented Supersonnerie architecture isolates the movement from the case via a suspended calibre plate and tunes the gong attachment points so that sound radiates directly through the case walls — producing a tone of extraordinary clarity, volume, and sustain.

The manually wound movement is enclosed in a 42 mm titanium octagonal case, the choice of material driven not by weight reduction alone but by titanium's superior acoustic resonance properties compared to gold or steel. A slide activates the chiming mechanism, which strikes hours, quarters, and minutes on demand in a cathedral-like sequence. The dial displays a warm salmon hue across the Grande Tapisserie guilloche surface — a combination that is as visually compelling as the sonic performance is aurally remarkable. Luminous Royal Oak hands and applied hour markers complete a dial of confident simplicity.

With a solid caseback that further optimises sound projection, a titanium integrated bracelet, and water resistance to 20 metres, this 26591TI.OO.1252TI.02 is presented with box and papers at $249,999. It represents the apex of Royal Oak horology: Genta's architecture serving not as a stage for visual complication, but as a precision acoustic instrument of the highest order.
