I am an amateur watch enthusiast and I'd really like to add a vintage Tissot watch to my collection. I came across the watch below with very limited information and photos. From my search on the web and forums I found that it is probably Tissot Aquasport Antimagnetique military watch from 1943 or around that era. Now I'm not sure if that is accurate or if this might be an entirely different Tissot watch. I find the history fascinating and I was thinking of a purchase but I'm not sure it's worth considering.
They are functional. The dial seems ok but the crystal might be cracked a little at the bottom (can't really tell, will ask for better photos). Unfortunately the back is pretty beat up and I'm not really sure what I can do about it...probably the only option is a replacement. I'm not asking for a valuation, I know that is forbidden here. I would just like a kind opinion of more experienced collectors about the state, history and if it's worth a deal (the asking price is 100 USD).
Any help appreciated.
Oh and I forgot to mention. I would probably clean the dial and hands a little
