Well, it seems to be an Ebel but I don’t know what model.
Biffo
I think G.B has nailed this one ! Looks so much like an Omega, but **el on the dial rules
that out. The escaping POW’s were all in the British RAF &, thanks again to G.B for pointing the way, between 1939-1945 Ebel ” went into production for RAF”
Model Ebel 6B/159
