These are Accutron clones, made by the Slava factory in Russia in the 1960s.
A customer had three parts movements, two pretty decent, and one very rough, and no good coils. I was able to make one running movement for him, and he gave me the remaining parts. I will be able to rewind and repair one or two coil sets and probably get another movement running.
I have no case, so I can't make a watch out of it.
