This masculine Audemars Piguet Royal Oak Concept Supersonnerie replica watch is their latest repeater milestone. AP has spent eight years working on their, as they say, most advanced minute repeater ever.
And in January 2015 AP showes the RD1 at the Salon International de la Haute Horlogerie Genève (SIHH). But they had to wait for some patents to be granted before the official launch of the new minute repeater could take place.
The challenge was solved by combining two things. A specific production process for the gongs and the way the gongs are attached to their foot. Normally the foot with gongs is attached to the main plate. A solution that leads to a loss of acoustic properties.
Audemars Piguet solves the first challenge by using a (patented) new design for the anchor governor. Normally the anchor governor or regulator controls the tempo of the chime making a buzzing noise. Other watchmakers developed centrifugal or air resistance governors to eliminate the noise. AP wanted to use the traditional solution, but without the noise. They designed a special shape for the anchor that absorbs the noise. This makes the mechanism almost totally silent. Here it is. In November 2014 Audemars Piguet launches a press release telling the world they are working on minute repeater. It is called the mens AP Royal Oak Concept replica Acoustic Research RD1.
Audemars Piguet attaches the gongs to a copper alloy resonance membrane which is sandwiched between the plate and the case back. This construction, with these materials and with apertures in the case back, enables a brighter, more natural sound. And it creates the possibility to make the Audemars Piguet Royal Oak Concept tourbillon chronograph copy watch water-resistant (up to 20 meters), which is not common with minute repeaters.
