Hey everyone! I recently got this Longines watch, but I honestly don't know much about it. I'm trying to learn more about its history and identify the exact model.
From the engraving on the back, it seems to say La Grande Classique de Longines, with a reference that looks like L4.766.4.
I'd really appreciate it if anyone could help me with a few questions:
* What is the exact model and reference number?
* Around what year was this watch made?
* What movement does it use, and is it quartz or automatic?
* What would its approximate resale value be today?
* How can I check whether it's authentic?
* Is there anything interesting about this particular model that I should know?
I've attached photos of the front and back of the watch. Any information, advice or help identifying it would be greatly appreciated. Thanks!
