Grande Sonnerie Supersonnerie

Avant-Garde Material Synthesis: 18-Carat Sand Gold & Black Ceramic

The highly technical case construction measures a standard 41 mm in diameter and an ergonomic 13.5 mm in thickness, demonstrating Audemars Piguet’s mastery of structural design. The watch relies on a multi-component architecture, housing a central octagonal case middle sculpted from robust, highly scratch-resistant black ceramic. This dark core is framed by a round bezel, stylized open lugs, and a specialized Supersonnerie caseback all cast in 18-carat sand gold—a proprietary new gold alloy that offers an elegant, warm hue bridging pink and white gold, delivering an impressive multi-planar aesthetic on the wrist.

Transparent Sapphire Dial Architecture & Calibre 2956 Metrology

The visual layout of this timepiece is centered around a crystal-clear sapphire dial, granting an unhindered view of the hand-crafted bridge work and mechanical gear train of the in-house Calibre 2956. The clear sapphire center is dramatically framed by a deep black external zone, complemented by a matching black sub-dial counter positioned perfectly at 6 o’clock. The broad hands and applied hour-markers are shaped from 18-carat sand gold and filled with premium luminescent material for nighttime legibility, all framed by a contrasting sand gold-toned inner bezel that amplifies the dial’s structural depth.

The Zenith of Acoustic Mastery & Patented Supersonnerie Acoustics

Beating inside is an elite manual-winding caliber executing horology’s pinnacle chimes: the Grande Sonnerie(striking hours and quarters automatically) and a bespoke Minute Repeater mechanism. This reference utilizes the brand’s patented Supersonnerie engineering, where the acoustic gongs are mounted directly onto a specialized sapphire resonance membrane acting as a crisp instrument soundboard. Coupled with an 18-carat sand gold Supersonnerie caseback and protected by a double glareproofed sapphire crystal, this closed acoustic system amplifies the acoustic vibrations, filtering out internal movement friction to project a loud, purely resonant chime on demand.
