In 2014,Audemars Piguet presented the Royal Oak Concept Acoustic Research Episode 1 watch, And at SIHH 2016,they launched new model which called Royal Oak Concept Supersonnerie, the brand feel they have produced a minute repeater of superior acoustic intensity with a supremely clear, sustained tone.
As with the first iteration of this project, the Audemars Piguet Royal Oak Concept Supersonnerie places emphasis on sound quality and clarity. Traditionally, when a minute repeater strikes, a background whirring can be heard. This comes from a component called the governor, which is in constant operation during the chiming process. 
With this watch, this essential component runs in almost absolute silence, reducing the distraction from the chimes themselves. In fact, Audemars Piguet is so passionate about developing the perfect-sounding watch, they’ve filed three patents in the making of the Audemars Piguet Royal Oak Concept Supersonnerie.
When Audemars Piguet released the original version of this watch, they spent time consulting with “an esteemed academic of the Geneva conservatory” to ensure the sound was not just clear, but also pleasing to the ear. And it must be pointed out that the titanium case allows this sound to travel through its walls with much less resistance than other common watchmaking materials thanks to its lower density than gold and platinum.
The Audemars Piguet Royal Oak Concept Supersonnerie watch is powered by a manual manufacture movement, known as the Calibre 2937. Considering its functions, it is surprisingly thin at 8.28mm. The watch operates at a steady 21,600vph, has 43 jewels, and 478 parts, with a minimal guaranteed power reserve 42 hours. The black ceramic screw-locked crown coordinates nicely with the black ceramic and titanium pushers used to operate the complication on demand.
The Audemars Piguet Royal Oak Concept Supersonnerie watch comes on a black rubber strap with a folding clasp in titanium. In addition to the stage-stealing sonnerie, the watch is also home to a tourbillon chronograph with central sweep-seconds hand and a 30-minute counter, which can be found at 3 o’clock. The minutes are indicated by a sweet, double-ended hand that rotates around its central axis and is read according to its coloured tips that correspond to the text on the dial.
It’s hard to consider this an everyday wear for anyone because of its delicacy and susceptibility to water damage, but the weight and muted colour scheme of the watch (and all Audemars Piguet concept watches,
