Thank you for the information you all have contributed. I really have been enjoying the watch more so, now that I know more about it.
I did take the watch in for repair to a reputable jeweler and watch repair place and was told it needed to be cleaned and needs a new spring. I went to pick it up today and the crystal looked different. Originally it had a scratch on the bottom and minor scratches on it. This crystal looked like it was acrylic, and didn't have any marks on it at all. The man said it was buffed and sanded but wasn't sure if it was replaced and was going to check with the person who worked on it. I left it there and told him I didn't want anything replaced on it just to get it running. I can't remember if the crystal had steps on the side of it? Is there anyway I can tell if it is the original one?
