I finally received my vintage Molnija komadirskie "death to spies"

The watch is supposed to be a vintage original serviced, manufacturing date 1970-1980. I would say it could be because the dial is a bit faded and the movement is stiff. The man who I bought it from on eBay sells other vintage USSR products and Vostok original movements. Any ideas I could specify the exact date it was manufactured? Any ideas? Either way I'm very happy I finally have this price, surprisingly the watch is quite big looks like a pocket watch turned wrist watch.
