Presented as a concept timepiece last year, one of the loudest and clearest minute repeating wristwatches around was launched this year as a production piece proper. The Audemars Piguet Royal Oak Concept Supersonnerie owes its sonic prowess to two innovations. The first is the silent governor, a mechanism that regulates the speed of the minute repeater chimes. While typical governors emit a buzz of some sort, the one inside the Supersonnerie works without a peep.
While the silent governor takes away any sound that might interfere with the repeater chimes, the soundboard inside the case amplifies the chimes to a remarkable volume. Instead of being fixed to the movement as in an ordinary repeater, the gongs of the Supersonnerie are attached to a copper disc that works like the soundboard of a violin or piano. Impressive as the repeater is, the Supersonnerie is also equipped with a chronograph and one-minute tourbillon for good measure.
Fortunately, the repeating mechanism can be translated to other movements, which bodes well for Audemars Piguet’s chiming watches to come. Audemars Piguet Royal Oak Concept Supersonnerie, $861,600
