Audemars Piguet Grande Sonnerie Carillon Supersonnerie "150th Anniversary"

Audemars Piguet's Grande Sonnerie Carillon Supersonnerie, reference 26397BC.OO.D357CR.01, has a 41 mm white gold case. The case measures 13.6 mm thick. A sapphire crystal covers the blue dial. The hand-wound calibre 2956 drives the grande sonnerie and petite sonnerie functions along with a minute repeater, an elaborate combination rarely seen even among Audemars Piguet's own output. Small seconds sit on the dial as well. The watch is fitted to a blue alligator leather strap closed by a white gold folding clasp. Water resistance is modest given the complication, rated to 30 metres.
