Kama (Vostok) 17 jewels USSR

Brand : Kama ( en.wikipedia.org/wiki/Kama_River )

 

"As far as i remember, Kama watches had a specific type of caseback that needs to be turned for 1/5 of its diameter, in a way similar to the cap of a fuel tank (sorry for the very silly comparison, but it's the easiest explaination that came in my mind)."
