Audemars Piguet Royal Oak Minute Repeater Supersonnerie in Titanium

Audemars Piguet unveils a new version of its Royal Oak Minute Repeater Supersonnerie in titanium. This complicated limited production watch is equipped with the ground-breaking in-house hand-wound Calibre 2953 which is protected by three patents. The timepiece is adorned with a refined and highly stylised guilloché dial in smoked grey hues to complement the titanium case.

Developed by Audemars Piguet and launched in 2016 in the Royal Oak Concept collection, the Supersonnerie mechanism endows this new minute repeater model with the volume and resonance usually associated with pocket watches. This patented technology results from 8 years of research in collaboration with EPFL, the Swiss Federal Institute of Technology in Lausanne. 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 exceptional acoustic performance, sound quality and harmonic tone are granted by the patented gongs, case construction and striking regulator developed at the time. The gongs are not attached to the mainplate, but to a new device acting as soundboard, which improves sound transmission and boosts sound amplification. The redesigned striking regulator – the device that sets the pace of the hours, quarters and minutes chiming sequence– has been revised and now incorporates an innovative, more flexible anchor system which absorbs shocks and eliminates unwanted noise.

Furthermore, an astute mechanical modification of the chiming sequence has mitigated the quarter-hour pause between the chiming of the minutes and the hours, when the watch does not strike the quarter hours. Last but not least, a security function prevents the wearer from activating the hand-setting function while the minute repeater mechanism is striking.

This technology equips the Manufacture’s latest hand-wound minute repeater movement, Calibre 2953. With its 362 components, it attests to Audemars Piguet’s uncompromising spirit with its blend of advanced technology and refined, traditional finishing.

This 42 mm Royal Oak Minute Repeater Supersonnerie encompasses a titanium case and bracelet both meticulously finished with an alternation of satin-brushing and polishing.

Furthering the piece’s monochromatic aesthetic, the smoked grey “Grande Tapisserie” dial subtly progresses into dark hues towards the dial’s extremity, nearly reaching pure black at the edges. It is complemented with white gold applied hour-markers and Royal Oak hands with luminescent coating for optimum legibility. The black small seconds counter at 6 o’clock echoes the inner bezel, while its snailed finishing contrasts with the Tapisserie motif.

The titanium caseback is engraved with the “Royal Oak Supersonnerie” indication and a sound wave motif.
