Vacheron Constantin Les Cabinotiers Symphonia Grande Sonnerie 1860
You would expect a manufacture with as long a history in making ultra-complicated watches as Vacheron Constantin to have made its first grande sonnerie sooner, but here it finally is. The entire watch took a single watchmaker 500 hours to assemble. A switch on the bezel lets you choose among the Grande Sonnerie, Petit Sonnerie and Silent mode, while a button in the crown activates a minute repeater.
