This signed watch by Auguste Meylan has a heavy gold case and a very finely executed champlevé enamel heavy gold dial. The enamel erotic scene is of very high quality workmanship depicting an aristocratic interior and is very similar to another watch made by Henri Capt. The erotic enamel scene on the present watch would of course have been supplied by the same enameller who made it for Henri Capt.
