Question about Casio G-Shock GW1200BA-1AV Wrist Watch

Casio GW-1200BA G-Shock

My automic solar watch is only 16 months old and no longer seems to be holding a charge even though the battery indicator reads full sometimes. I cannot set the analog watch hands, my light flashes on for a nano-second, and, everytime I press any function, it sends the watch into "recover" mode. I love this watch and it worked fine until now. Is this a common problem? What's the fix? Please help. - Steve

    I've had the same problem with mine - definitely a problem in the product design as I'm seeing this all too common problem posting at various sites

    Same issue.  Full charge, then suddenly hands are at 12 o'clock and flashing low battery.  Wait 10 minutes to half hour, then back to normal, full charge again.  Has happened a few times since I bought it in March 2006.  Haven't contacted Casio yet (no warranty now) because it doesn't happen too often yet and I'm assuming it'll be about a $200 repair given what others have said.  I'm assuming it's a module, not the battery, because once it's back to normal, I can do all functions (light too) repeatedly without it shutting down again.  Too intermittent to be the battery in my opinion.

I got the watch repaired about 10 months ago where the battery indicator would show low battery, the hands would show midnight and then after about an hour the watch would be normal. I spent $135 to get the watch repaired at an authorized Casio repair facility in NJ and the technician said that inert gas Casio uses to keep moisture out had leaked out and moisture got inside which basically ruined the electonics. It seems that this watch has design issues. Unfortunately Casio does not stand behind their products. Now the same thing happens again 10 months after being repaired and the hands (analog) show a different time than the digital time.

I have had a similar problem with 2 of these watches now. I got my first one Christmas of 2006 and it would be fine 1 miniute and then the hands would go to 12 and it would show low battery, a hr later it would be fine and show a full charge. After this happening 6 times I sent it back to casio and they said it was the module and wanted to charge me over $ 200.00. After I complained that I had only had the watch fopr 5 months they sent me another one. I am now having the same problem with the 2nd watch. I love this watch, but think their is a design flaw somewhere. If you are considering this watch beware.

Try taping it to the inside of your window for a couple days and see if that makes it charge up enough to act right. You might also want to make sure that you don't have the "auto light" on. If the light turns on when you tilt the watch to a 45 degree angle then press the light button for 2 seconds to shut that off. If that doesn't work for you then you are probably going to have to have the battery changed.

From your description the solar cell charges the battery and keeps it topped up. I think the rechargeable battery is the problem because when the screen goes blank the battery level drops to low and the LCD blanks out which would explain the intermittent operation of the watch. I think it is worth getting it checked out with an estimate.

Change the battery. This happened with mine along with the battery needing charging more frequently. In my opinion, Casio's assertions that you won't need to change the battery is pretty much of a joke. My jewler concurred.

After changing the battery I can now press the light switch button and the watch works normally.



My watch had the same problem and i could never figure out what it was so i just lived with it for a couple of years. then, just recently even when my watch was getting plenty of sun the battery would die in the evening and shut off at night. so i replaced the battery and evrything works great. even the light which leads me to believe the solar panel is just a gimmick. i have an old g-shock watch that i bought in 1989 and it still works and is on the origional battery. my gw 300 is about 5 years old and needed a battery. i guess 5 years on a battery is prety good but i would rather have it last for 19 years like my old one.
