Watch quality marking of the city of Geneva
The Geneva Seal (also called Hallmark of Geneva, Poinçon de Genève) is a seal of quality watches of the Geneva examinig office “Bureau Officiel de l'Etat pour le contrôle facultatif des montres de Genève”, awarded since 1886. 1957 and 1994, the regulations were revised and now comprise 12 specifications for exact processing and adjustment of movement parts, but no accuracy testing.
Only watches can obtain the Geneva Seal which are assembled and regulated in the Canton of Geneva.
