The first calibre with the Hallmark of Geneva
In 1901, the first Vacheron Constantin calibre receives the Hallmark of Geneva. This certification, created in 1886 by the Geneva cantonal parliament, was intended to preserve the skills of Geneva’s watchmakers and protect them from the unlawful use of the Geneva name.
The Hallmark of Geneva is today considered a mark of watchmaking excellence
because it guarantees the provenance, quality, accuracy and endurance of the watch. Vacheron Constantin is the oldest watchmaking firm that has its movements stamped with the Hallmark of Geneva.
