Posted this in the Hamilton forum but was told that it would be better suited here.
I'm new here and relatively new to the world of watch collecting. One of my first watches was this Hamilton which I acquired a year ago. My local watchmaker says that it is a Thinline from mid 60s but he cant be sure. It doesnt really match catalog pictures exactly so I am concerned it may be a fake? Here are pictures of the watch. (Sorry no pics of movement, not sure how to open the case and I don't want to force anything) Any help on opening the case would be appreciated as well..
Case is 33mm across excluding crown, 40mm lug to lug.
