Audemars Piguet Grande Sonnerie Carillon Supersonnerie

Audemars Piguet's Grande Sonnerie Carillon Supersonnerie, from the Code collection, reference 26397NB.OO.D002KB.01, has a 41 mm black ceramic case. It measures 13.6 mm thick and carries a sapphire crystal over an openworked dial. The manual-winding calibre 2956 drives the watch, combining a Grande Sonnerie Supersonnerie with a minute repeater and small seconds display. This is a rare piece of horological engineering, built to chime the hours and minutes with a resonance chamber designed to project sound clearly through the ceramic case. The black rubber strap has light grey stitching and closes with an 18-carat white gold folding clasp. Water resistance is modest for such a piece: the case is rated to 30 metres.
