Audemars Piguet Grande Sonnerie Supersonnerie

Audemars Piguet's Grande Sonnerie Supersonnerie, reference 26397OR.OO.D417CR.02, comes in a 41mm rose gold case measuring 13.6mm thick. The green dial sits under a sapphire crystal and carries small seconds as its only running indication. Manual-winding calibre 2956 drives the watch, and it delivers the Grande Sonnerie and Petite Sonnerie strike modes alongside a minute repeater, chiming the hours and minutes on demand. This is a rare combination of complications, built around acoustic performance rather than display alone. The green alligator leather strap closes with an 18-carat white gold three-blade folding clasp. Water resistance is a modest 30 metres, in keeping with a watch built for sound rather than diving.
