Bulova accutron pocket watch
I am trying to find information about my Bulova Accutron pocket watch. I took it to a local jeweler and had the battery replaced, but he wasn't familiar with this watch, so he really couldn't tell me much about it other than that he thinks it was made in the 1960's. I will post a picture, but I am afraid to open the back cover because I don't want to damage it, and there are already tool marks where someone tried. It makes a humming noise, and it intensifies when you place it on a hollow object, resonance from the tuning fork inside I guess.
