S/N  : The small number of watches examinated ( 4 ) does not allow to define a range .

            1. EMCO was a sub-brand of Rado

                In all respect , this watch was an Helvetia . The explanation can be sought in the fact that ,

                for a period  ,“ La Generale / Helvetia Watch Co“ had a partecipation in Rado ( 1938 – 1941 ).

            2. A singular fact is rapresented by the letters “ D.H. “ punched on the Helvetia  code  number (3190)

                instead on the S/N . This is on all watches seen ( 4 ).
