It's a caliber 12.68z, a pretty common 1950s movement. I see you have an extract from Longines, too, which says as much. It has a replacement crown, and the dial may be refinished (hard to tell with this photo strip, better photos would help). Why don't you tell us what you think of the watch, and we'll take it from there?
Anyone can share some light on this watch on its originality in the dial, bezel, hands, case, crown or movement. Hope to learn more on this watch. Thanks.
It's normaal to have done some initial investigation and research yourself, then come here to check out whether your findings are correct or not....
Soonfeeding information to noobs is not really what the forum is for and you'll have much better responses to your posts if you first put some effort in yourself.
The dial is refinished. Wrong chracter style, minute markers printed asymmetrical ON the golden markers.
The case doesn´t like a Longines. "Fond Metal" is impossible for a quality watch.
