I'm hoping someone can give my some information on a Stowa wrist watch that I recently acquired. I'm new to watches, but find myself drawn to vintage watches for their personality and history. I am considering taking this watch to a watchmaker to be cleaned and serviced so I may use it. It will run for brief periods after winding, but is difficult to wind. Perhaps it has been over-wound. Although I could open the case back, I don't have the proper tools and I don't want to scratch it. Here are some photos:
I appreciate any information that you can give me.
