Hi, I am quite a rookie when it comes to vintage Longines, and would like some help with this Longines. Anyone who can help with a bit of info? Thank you very much!
Looks like a late 50's or 60's manual winder, probably with a 23Z or maybe a 370. A look at the case back would help.
I'm really leaning towards a 23Z now. Have a watchmaker pop it open and get a clear picture of the inside of the caseback and the movement so the numbers are all visible.
