Poinçons de Genève. The voluntary quality control of watches at the Geneva Observatory was established by law on November 6, 1886. Conditions were laid down for the attribution and stamping of the Poinçons de Genève, punch marks representing the coat-of-arms of the city of Geneva. Pocket watches and wristwatches which carry the Geneva Mark, considered the equivalent of the ‘Bulletin Officiel de Marche’, stamped on a bridge and on the main plate of the movement, may be officially termed ‘chronometers’.
