Another watch I can't identify due to a lack of markings. The case is stamped "cylindre, 10 rubis" which I take to mean it's a cylinder type, and it's 10 jewels. Could be French but I think far more likely it's Swiss. For some reason a lot of early Swiss movements aren't marked. Pendant wind and set. Not working.
