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 ( 3 ).
