The Geneva Seal: What the Poinçon de Genève Actually Guarantees, From 1886 to Today
The Geneva Seal (Poinçon de Genève) is a state guarantee established in 1886, originally certifying a watch's Genevan origin and movement finishing. Since 2011, it has expanded to include rigorous testing of the complete watch's performance, accuracy, and durability.
