Artistic new chimers from Audemars Piguet
The Code 11.59 by Audemars Piguet collection has been increased with the release of five Grande Sonnerie Carillon Supersonnerie timepieces, each endowed with a unique bespoke enamel dial crafted by Anita Porchet and her atelier
Chiming watches bring us back to the origins of time measurement devices: invented in the 14th century, striking clocks chimed time exclusively as they were devoid of dials. Audemars Piguet has specialised in chiming mechanisms since its establishment in 1875 and crafted complex Grande Sonnerie, Petite Sonnerie, and Minute Repeater mechanisms ever since. Today, only a handful of specialised watchmakers at Audemars Piguet are trained to assemble and adjust a Grande Sonnerie, which is considered as one of the most sophisticated complications in the history of Haute Horlogerie.
To celebrate the complexity and rarity of Grande Sonnerie watches, Audemars Piguet has collaborated with renowned Swiss enameller artisan Anita Porchet on hand-crafted “Grand Feu” enamel dials. For the occasion, she created a trilogy of enamel dials decorated with antique gold spangles (“paillons”) over a century old, seamlessly blending ancestral savoir-faire and contemporary design. Anita Porchet’s artistic work and know-how have been praised by some of the most respected Haute Horlogerie manufacturers in Switzerland, her refined enamel dials adding an artistic touch to the complicated timepieces they adorn.
For the remaining two pieces, clients have the possibility of requesting a personalised enamel dial crafted by Anita Porchet’s atelier.
The Code 11.59 by Audemars Piguet Grande Sonnerie Carillon Supersonnerie houses a new hand-wound movement, calibre 2956, which unites the traditional Grande Sonnerie complication with the patented Supersonnerie technology introduced by the Manufacture in 2015 in the Royal Oak Concept collection. This complex calibre of 489 components testifies to Audemars Piguet’s uncompromising spirit.
A Grande Sonnerie timepiece not only strikes the hour, quarters, and minutes on request as a traditional minute repeater would do. Like a bell tower, it can also strike the hours and every quarter hour by default, without any involvement from the wearer. A carillon means that the Grande Sonnerie Supersonnerie is endowed with 3 gongs and hammers instead of 2 on a standard chiming watch and therefore strikes the quarter hour with three successive notes (high, middle, low) instead of two. In the Petite Sonnerie position, the watch chimes the hours only, while the automatic chiming is deactivated in the silent mode. As for the minute repeater mechanism, it can be activated by the wearer at any time.
The added Supersonnerie mechanism grants this complicated wristwatch the acoustic performance of pocket watches. This patented technology is the result of 8 years of research in collaboration with the Swiss Federal Institute of Technology Lausanne (EPFL). Inspired by the sonic power of older minute repeater watches as well as by the harmony of musical instruments, a dedicated community of watchmakers, technicians, academics and musicians reviewed the case construction to produce a new chiming technology.
The Supersonnerie’s acoustic power, sound quality and harmonic tone are granted by patented gongs and case construction. The gongs are not attached to the mainplate, but to a new device acting as soundboard, which improves sound transmission. This innovative Supersonnerie technology also provides a sharper tempo.
Hand-decorated to the smallest detail with refined finishing techniques, the calibre 2956 further blends tradition and innovation.
Each “Grand Feu” enamel dial is unique due to the organic nature of its materials, as well as the hand manufacturing technique and distinctive cooking time. A thin layer of glass sand mixed with water is applied by hand on the gold dial, before being heated at more than 800°C in a dedicated oven. The procedure is repeated multiple times to achieve remarkable transparency, depth and light. Each cooking session necessitates different temperatures and times; a perilous procedure requiring extensive knowledge of colour alchemy.
Inspired by Code 11.59 by Audemars Piguet’s unconventional design, Anita Porchet has explored new creative possibilities by decorating each contemporary “Grand Feu” enamel dial with antique hand-crafted gold spangles, at least a century old. Each spangle was meticulously cut and curved in thin gold leaves with antique tools and techniques – a craft no longer perpetuated today. The enameller has carefully incorporated each spangle by hand onto the dial’s enamelled plate before fusion in the oven. The dial is then covered with a thin layer of transparent enamel for a mirror polish finishing.
The 18-carat white gold case’s ergonomic curvature and seamless combination of an octagonal middle case with a round extra-thin bezel and stylised arched lugs made the conception, manufacturing and decoration of each component particularly intricate. Complex programming, dedicated tools and specialised human talents had to be combined for the industrialisation and hand-finishing of the components. The case’s juxtaposition of angular and rounded surfaces presented a real challenge to the manufacturer’s finishing experts. The perfectly aligned alternation of satin-brushed and polished surfaces adorning the case is only achievable by hand.
