Notes

Vianney Halter is a member of the prestigious AHCI, or Academie Horlogère des Créateurs Indépendants in Switzerland and has also created his own company, Janvier SA. His version of the Goldpfeil watch was entirely developed by himself and is equipped with his self-winding mechanism. The moon phase of this watch is one of the most precise ever created. There are 2 systems in general use today; the most common one has a one-day error margin over a period of approximately 2 1/2 years, the other one ,used only by a few high-end brands has an error margin of one day every 122 years. Both systems are adjusted once every 24 hours. The gear train developed by Halter, and used exclusively in this watch, readjusts itself every 6 hours for an even greater accuracy of one day every 139 years.
