Vacheron Constantin Traditionnelle tourbillon chronograph

The Traditionnelle tourbillon chronograph (reference 5100T/000R-B623) is part of Vacheron Constantin's Traditionnelle collection. The 42.5mm round case is made of rose gold with a sapphire crystal and a white dial, and is rated to 30 metres of water resistance. It houses the manual-winding calibre 3200, which combines a tourbillon and chronograph function and provides a power reserve of 65 hours. The watch bears the Poinçon de Genève, a hallmark introduced by the Republic and Canton of Geneva in 1886 to certify watchmaking quality and provenance.
