Could this be my new watch?

Both state they were made in the "CCCP" (USSR) so pre-1989. Both appear authentic and from a well-known and respected seller judging by the photos and background.

I think what you're seeing is a dirty or missing movement attachment screw and both such screws look too small. I would say in general that whole movement looks a little dirty and not what one would expect from the nice condition of the dial and case so perhaps all those parts didn't leave the factory together? Also the crown is sticking out which could mean the seller forgot to push it in after setting the hands or it is the wrong length shaft. I would buy that one only if the price was too good to pass up, personally.

Oh, and also big zero 101: Only blunt hands are authentic. Since it was made for sight-impaired people the skinny batons don't make any sense. Definitely replacements, in my opinion. Pass!

Welcome....revisit the guy you were originally considering, he has a couple that you might want to follow. Good luck!
