I've done a fair bit of searching and keep coming back to here. I've inherited a few pocket watches and old wrist watches. I'm most interested in finding out a bit more information on this pocket watch. All I can tell you is it was purchased somewhere round the 30's by my great grandfather. The pictures are not great, the case is made by Dennison and has a case number of 280628.
I'm unsure where to find the actual movement serial number. I hope I don't annoy anyone with my ignorance, I'm a newbie when it comes to watches.
