I pulled this out of the junk box and saw that it has the 691 Module. WUS and Google tell me this is vintage. Since it works, I was going to clean it up and add it to my 3 other G-Shocks. The battery has to be over 10 years old. Here is my question: Should I hold onto this watch since it has the 691 module or, does it hold little value? The Internet returns values all over the place.
Sorry if this is a rookie G-Shock question. New to the G-Shock Forum
