Not sure if this is really old enough to qualify as vintage, but we'll try it here first.
I'm having trouble finding any information on Lugran. Movement seems decent enough -- is a 21 jewel ETA 2772, adjusted to 3 positions. Non-hacking, non-quick-set date, 21600bph. In addition to the eta logo and 2772, there is a mark that appears to read "OT". Any idea what that might signify?
Despite evidence of moisture, it is keeping good time. A little difficult to set, as the crown wants to unscrew from the stem -- is this something a ham-fisted amateur could fix, or better left to a professional?
Hard to tell from the poor photos, but the dial is a very deep blue. The crystal is badly scratched, but doesn't look quite as bad in person as in the photo.
Any ideas on vintage, or information on Lugran would be appreciated. Also, an idea of where this watch would have stacked up next to the more recognizable brands at the time.
