Its titanium tourbillon cage is still the smallest in the world at 7.2mm in diameter, as well as the lightest at just 0.123 grams.
This model became known to timepiece enthusiasts as the Tourbillon Automatic RA, because Jacqueline Dimeier’s design gave the small regulator (one of the smallest ever produced) the appearance of the Sun, whose rays spread across the dial.
This complex wristwatch would be produced in 401 copies for a few years until 1992. This opened a new path for haute horlogerie which then revived iconic mechanisms including tourbillon watches.
Thirty years after Jacqueline Dimeier’s model, AP Manufacturing, known for its ability to innovate, is launching a series of research and development models. In 2015, Audemars Piguet unveiled its first prototype, the RD#1 Royal Oak Concept Répétition Minutes Supersonnerie.
The result of eight years of research in partnership with EPFL (इcole Polytechnique Fédérale de Lausanne) and with a panel of experts made up of watchmakers, engineers, musicians and sound experts, this watch incorporates supersonry technology.
The subject of three patents, this system, which combines an attractive mechanism and an innovative box architecture, marks a significant advance in terms of acoustic performance, diffusion volume and sonic aesthetics.
Introduced at SIHH the same year, the RD#1 would enable the construction to launch a year later a marketable version of the Royal Oak Concept Repetition Minutes Supersonerie, winner of the Grand Prix d’Horlogerie de Geneve in 2016 in “Mechanical Exception”. Were. “Category.”.
In 2019, AP launched the Royal Oak Calendar Perpetual Ultra-thin Automatic 41mm, the innovative prototype of which was presented at SIHH a year ago as the RD#2.
This calendar watch, whose case is 6.3 mm thick, has a movement of only 2.89 mm thick, making it the world’s thinnest automatic calendar wristwatch at the time.
To achieve this feat, calendar tasks usually held at three levels have been brought together on a single plane. Manufacturers’ experts have also developed two patented innovations relating the month end cam to the date wheel and the month cam to month wheel engagement.
Marking a turning point in the history of complex watches, the Royal Oak Calendar Perpetual Ultra-Plate Automatic will earn Audemars Piguet the Grand Prix de l’एguil d’Or at the Grand Prix d’Horlogerie de Geneve in November 2019.
This year, Manufacture at Le Brassus revealed its new technological breakthrough with the Royal Oak Extra-Plate Automatic Flying Tourbillon.
