I haven't opened the case as yet, but was wondering if anyone has replaced (or attempted to replace) a crystal in a Frogman DW-8200. From the way it looks, it appears to be a standard circular crystal (not sure about the thickness yet) and should be fairly easy to replace. It does not appear to be sub-surface printed, but I can't be sure until I open it up. I have a crystal press and likely the correct size crystal (as long as it's nothing unusual) so I was wondering if anyone has any experience in this little project. Thanks in advance for your input!
