At La Chaux-de-Fonds, the master enameller becomes an expert in traditional techniques such as cloisonné, champlevé, plique-à-jour and grisaille enamel, as well as techniques that the Maison des Métiers d’Art has developed or revived, for example gold paste enamelling, filigree enamelling or enamel granulation, which differs from other enamelling techniques due to the fact that the enamel beads, or balls, are created using a blowtorch, not in a kiln. It takes almost 30 hours to create an enamelled dial and the piece needs to be fired in the kiln around 10 to 15 times to obtain the different shades.
