All the info about Identifying it is posted here. The condition of the dial and case speaks for itself. We haven't seen the movement or the back so that can't be evaluated.A single picture is never really enough to go on as most collectors here will tell you.
..Best do a little looking around.. If you're a collector you'll know where to go online and search out similar examples and see what they sold for, or how much people are currently asking for them...usually a big gap between these prices...the average value is somewhere in the middle at the lower end.
Thank you very much for the answers chipsotoole and tyrantlizardrex.
I'm happy to have found this watch anyway. Paid nothing but already knowing the historical period is important to me
Tks!
