A watch must respect precise criteria to obtain the Geneva seal certification and some operations, as the assembling for instance, must be done on its territory. At Vacheron Constantin, the process begins with the finishes and ends with the final tests as the accuracy for instance. The criteria have been defined in a law that has been adapted in 2011 and the controls are managed by Timelab, a dedicated office. Join The Watches TV to see how a watch get certified.
