Audemars Piguet Royal Oak Concept Supersonnerie

About this reference

The Audemars Piguet Royal Oak Concept Supersonnerie reference 26591IO.OO.A002CA.01 was introduced in 2016 and remains a low-volume production piece within the brand’s high-complication catalog. Collectors prioritize this reference for its caliber 2937 movement, which utilizes a patented soundboard technology and a unique striking mechanism designed to amplify the minute repeater’s chime. The 44mm case is constructed from sandblasted titanium with a black ceramic bezel, screw-locked crown, and pushpieces. Its openworked dial features a black 30-minute counter and yellow accents for legibility. This reference represents the commercial application of the RD#1 prototype, focusing on acoustic performance in a water-resistant case. On the secondary market, this model typically commands prices in the mid-to-high six-figure range, often between $350,000 and $550,000 depending on condition. A notable production detail is the caseback’s "sonic" perforations, which allow sound to escape while maintaining 20-meter water resistance.
