New vintage STG GDR silver 7” serpentine chain bracelet

New vintage STG GDR silver 7” serpentine chain bracelet Minimalist classic all around chain. Thick enough to be noticed when worn alone. Thin enough to layer with other bracelets. Wear day to night and in the shower. NWOT Vintage C. 1970s. Flat Serpentine chains have a high surface area that shines and catches the light. I thought GDR: meant German Democratic Republic or East Germany (c. Post-WWII - 1990 unification). But it is from a Montreal jeweller who came once a year with beautiful gold and silver.
