Question about Casio G-Shock GW300CA-1V Wrist Watch

2 Answers

You didn't have GW510A (limited edition) Assume this is similar?

Because its old battery was not holding a charge, I bought a new CTL1616 battery for my G-Shock GW510A. I need instructions on how to replace the old battery. Thanks for any help.

Re: You didn't have GW510A (limited edition) Assume this...

It's a common problem, now that the earlier Tough Solar watches are getting on in years. Plus, there was apparently a bad production run by the battery manufacturer (Matsushita/Panasonic), so there's a certain subpopulation of G-Shocks that are seeing premature failure.

Replacement is easy. You'll need a jeweler's screwdriver set, ideally some plastic tweezers (though a toothpick will do), some metal tweezers for one of the final steps (but not for handling the battery), and if you're smart some latex gloves to keep everything pristine. Get a little tube of silicone grease, too (and ONLY silicone). Careful with it, though-- it's impossible to wash off of clothing, etc.

It's all proceed-at-your-own-risk, of course, but good instructions are posted at

Mind the little springs, and note which one came from where.

Altogether, it's an easy job. Good luck!

I have a Casio 2688 atomic watch and lately it does not hold a charge for a long period of time. It will recharge and then quit within a day.It will hold a medium charge for about 24 hours at most, but...

You likely have a dead battery. Follow the instructions on this web site
it is clear and covers most casio models. Watch closely for the springs when taking your watch apart. You can order the battery online (the best option) but most people that use a standard lithium battery seem to have no problem.

I have replaced the batery several times and the watch does not keep time and stops.Lucien Piccard 26489

mcdevito75 Here, hopefully you didn"t buy the batteries all from the same store, as watch batteries and all batteries have a shelf life of not too long. You may have bought weak batteries if all were bought from the same store, nothing to do about that as who knows the strength of packaged batteries. If you did buy all the batteries from one store, try another store and buy another battery, If the watch still stops and goes, your watch may be wearing out, specially if the watch is over 10 years old.

I left my watch in the dark for a along period of time. The indicator shows low / I have been placing my watch on direct ligth so can charge for the last 4 days . Do i need to replace the battery CTL1616

If you left your watch in direct sunlight, there should be just 6-8 hours enough to recharge it. If there was no direct sunlight, it may take up to a week to revoke your watch. This corresponds only to watches powered by light. The energy cell in those watches is called capacitor, not battery. If you are not sure what type of cell your watch has, leave it for a few days more in bright lightened place and then see if it works. If it does not - replace the capacitor (or battery if your watch isn't powered by light). Rate me, plz.

CTL is the designation for a rechargeable secondary battery. The CR is a primary disposable battery and is a 3 volt cell. The CTL1616 while the same size as the CR1616 function completely differently and are not interchangeable. The CTL1616 is 2.3 volts and is recharged by solar or light or kinetic movement. The CR1616 is 3 volts is not rechargeable and will not function properly in a time piece designed for a 2.3 volt circuit. There is only one manufacturer of the CTL1616, Panasonic and they sell through Casio parts distribution.

Battery issues,......

Hey all, here is a site that has good instructions on how to change the battery in your G-Shock watch. Sounds like you are suffering a low batt problem.

If you want to ensure you still have a the same water resistance rating, I do suggest that you take it to a watch guy to have it replaced for you. They clean switch contacts also and you keep water resistance rating. Good Luck and vote this as a "FixYa". Cheers
