Looking good. I don't know about the case back. Look here:Hi!
This Moskva/Москва Watch is currently available on the Bay.
Are the hands original (central second is quite shiny!)?
I like the case-back. Any idea why it is so thick and domed?
Does the movement (type?) seem repaired or not?

Hands are often the best looking parts of an old watch since, unlike the case, they are protected and usually finished much more durably than the dial.
