Audemars Piguet Grande Sonnerie Carillon Supersonnerie "150th Anniversary"

Audemars Piguet's Code 11.59 Grande Sonnerie Carillon Supersonnerie "150th Anniversary", reference 26397CR.OO.D009KB.01, comes in an 18-carat rose gold case measuring 41 mm across and 13.6 mm thick. The openworked dial exposes the rhodium-toned architecture of the hand-wound calibre 2956, visible under a sapphire crystal. This is a watch built around sound: the movement delivers a Grande Sonnerie Supersonnerie and Petite Sonnerie alongside a minute repeater, with small seconds as the sole subsidiary indication. The chiming mechanism is paired with acoustic engineering meant to project the strikes clearly through the case. A grey textured rubber strap with calfskin lining completes the piece, closed by an 18-carat white gold folding clasp. Water resistance is a modest 30 metres, in keeping with the demands of housing so intricate a striking mechanism.
