About 12 years ago, my old 6900 finally died. I knew it was a battery but nobody would change it. I always heard that they needed to go back to Casio. I was in the mood for a new G Shock so went and bought a new watch. After 12 years, it finally died the other day. I took it by a local jeweler and he said he would take a look at it. I decided to shop around and discovered this site. I just ordered a GX-56. I also checked out how to change a battery in the forums here. I figured that I could do it so ran and got a new battery. So with a little screw driver, a pocket knife, and a paperclip, I changed out the battery. After all these years, an old friend is working again and still sporting the Fat Eddy's watchband. Now I need to go by the jeweler tomorrow and get my other watch from him and fix it myself. Also think she deserves a new band. Might have to give a Zulu a try. Just not sure if they are big enough to fit my fat wrist.
