Audemars Piguet Minute Repeater Supersonnerie

Audemars Piguet's Royal Oak Minute Repeater Supersonnerie 26591CE.OO.D002CA.02 comes in a 42 mm black ceramic case. The case measures 14 mm thick and carries a sapphire crystal over the black dial. Inside is the manual-winding calibre 2953, which drives the minute repeater and small seconds display. Baguette-cut diamonds mark the hours, set against the "Grande Tapisserie" pattern. This is a special edition, built around the Supersonnerie system that amplifies and refines the chiming sound. The black rubber strap closes with a titanium folding clasp. Water resistance is a modest 20 metres, a figure that reflects the priority given to acoustics over depth.
