I digged up a watch from my childhood -- Casio racing game watch! Its likely to be from around 1982 or so. The watch is still in decent condition. Unfortuniately there is a bleed in the LCD on one of the corners. The strap (not original) will need to be replaced since it looks like its going to crack any time soon. LOL
I haven't try to open it up and replace the better yet. I am planning on restoring and wear it proudly. :D
I am looking for information on the type of battery that it uses? Is the A/C reset contact easily identifiable? Any photo online with the caseback off? I don't think the caseback gasket can be sourced unless gasket from other recent models can retrofit in it.
