I think that this is some variant La Petite family
case and movement stamped L7
these watches are functional have broken balance
JP Thanks for the offer, this watch I bought at auction a lot of cheap. Also, I am not youngest and therefore I have no eyesight very best. If I can get a functional movement that would be better. If it does not to get back to you and I'll try to fix it for practice. Most 5AD movements that I found were exactly the same defect - broken balance.

It does have characteristics of "La Petite family" :) I'll hunt for an ad. One 1955 ad from this thread . Do all "La Petite family" have diamonds? Does subject watch have a couple diamonds on lugs?
