Lovely watch! Can't really tell the model but the 6 digit serial at the back and lack of "Swiss" or "Swiss Made" on the dial seems to suggest it came from the satellite factory in Bresancon, France. If so, case serial range dates it to ard 1960ish? If you have a competent watchmaker in town, get him/her to get the caseback off and take a few pictures of the movement and the inside of the caseback. That'll help in the sleuthing.
And oh yes, Dibs!
