Swiss Watch Fair 1970 BF 937
Here is an elegant dress watch. Yet it is self-winding, waterresistant and shock-protected. In fact, it benefits from all the advantages of men s models. Inside the case is the famed differential movement in which a planetary gear separates the energy needed to keep the watch running from that which can be stored in the mainspring, and to which a calendar system has been added. Steel case. (ZENITH)
