Audemars Piguet Royal Oak Minute Repeater Supersonnerie 42mm

The Audemars Piguet Royal Oak Minute Repeater Supersonnerie 42mm is lauded for integrating the Supersonnerie chiming mechanism into the Royal Oak case, achieving a louder-than-average sound due to its gongs mounted on a soundboard and a specially designed caseback. This innovative construction, which includes a resonance membrane and patented gong manufacturing, addresses acoustic challenges in a smaller watch case, allowing for 20 meters of water resistance. The watch is available in titanium with a blue dial or platinum with a black dial, each limited to 20 pieces. One owner finds the 42mm size too large for the Asian market. Overall, owners and reviewers praise the Audemars Piguet Royal Oak Minute Repeater Supersonnerie 42mm for its groundbreaking sound volume and innovative case construction.
