Watches can be damaged without proper handling and while the repair you are about to attempt may seem simple, you can easily break or ruin the watch with any small mistake. If you have any doubts about this repair, do not hesitate to take your watch to a professional watchmaker or jeweler..

[@jmflyer55]

Thanks for posting, the only thing I would add is to lubricate the case gasket otherwise this watch has lost its water resistance. Thx....JM

Just finished installing a new solar watch battery in my Casio MTG 1000 (just like in the video). Followed the instructions step by step. This was the best DIY video that I have ever seen. Saved money and saved one more watch from going into the land fill.

[@Fomites]

Thank you! This is a highly professional and thorough video. No details have been missed - every step is documented. One of the best instructional videos I have seen. Congratulations!

[@JamesPortland]

Thanks, looked fairly easy but I forgot where the springs went so your video helped me make sure they were in the right place. Got it all back together and it works just fine again.

[@oldbones9162]

Gotta thank you for this video! Was able to replace the battery in my watch. Although I had problems with the machine screws on the back plate where the heads stripped and need ground off to remove hat plate….everything else fell into place. I’ve owned this watch for way over 10 years and maybe a lot longer…I lost count and just now requires a battery replacement. What a watch! So glad to have on the wrist again and it’ll probably outlast me! Thanks to your review!!

[@elploppy]

Excellent video. My G-Shock has been playing up for a while now. Thanks to your excellent video I feel empowered to change the cell myself rather than trust the task to a top town battery change boutique. Many thanks.

[@Sparks52]

Do NOT EVER have a battery change done by the "town battery change boutique" in a watch that cost more than $10 new. They damage and destroy more watches than you could ever imagine.

[@DaleTrimm]

Thank you!!! Got my battery yesterday and popped it into the watch today... now I"m fully charged and ready to go again!! GREAT video...

[@mwrayjr]

Thank you. Step 12 and the AC power reset was something I hadn't seen highlighted in similar videos.

[@PeterJohnsonJr]

This was a perfect video and made it easy to restore my wife's dead g shock by replacing the battery. Thank you very much.

[@maboleth]

You can open the battery latch with a toothpick faster and causing no damage at all. It fits perfectly to that latch hole and since it's wood, it won't damage this delicate metal part. When closing it back, it's enough to just push the battery and latch downwards gently and it will click. No need to use tweezers since that can stretch it and bend other way.

[@Johnny-kn9pj]

True, a needle works too

[@OutdoorsIQ]

Good insight, thank you

[@electrogestapo]

this was informative. I was planning on replacing the battery on my old triple sensor and had no idea it's exactly the same as any of my regular G-shocks. I was originally not even sure it's battery can be replaced.

[@andymkhome6572]

Thanks for the video, gave me the confidence to change my 10+ yr Casio Wave Ceptor 4719 battery. Used latex gloves. fiddled around for a while before the +ve/-ve bit worked, thereafter the watch cam back to life.

[@kozzmik]

Thanks for video. I ordered my battery from you guys and watch is running great again. Also I have to say I'm impressed with how quickly I got it. Within a couple hours of ordering I had confirmation it shipped, and two days later it's here. Price was also the lowest I found. All around great experience. Thanks again

[@nevose9046]

Thank you. After about 10 years I think my original battery finally has met it's end.

[@Bippy55]

This was one of the BEST DIY watch repair videos I've ever seen. Pacing a bit slow... but that's okay to cover all the bases. My thanks to the video creator. I am thinking about changing a battery in my solar powered CASIO G-Shock multi-band 6 watch. But I am also wondering if there is a service center that will do it for a fair price.

[@Esslinger]

+David Boyer Thanks David, We are happy that it was helpful to you. We will continue to try to improve our videos and keep it "on pace". We do not have a recommended service center but there are some listed on the official Casio site.

[@tarheelred28390]

*That dog-gone screwdriver block for removing double ended screws is what I need, jack!*

[@318tags]

Spectacular video...just what I needed to confidently change my beloved casio solar. Thanks

[@varlainsystems3364]

Great tutorial. Just extended the life of my G-Shock 3366 hopefully for another 15 years!

[@tundra75]

I bought my G-Shock MTG-M900 in October of last year. Thank you for this video, will definitely bring it back up in around 15 years. lol Great Video!

[@kennethpon9498]

Excellent video. Even though I have a PAS400B-5V "Pathfinder" Resin Fishing Watch, the battery latch mechanism for your watch and mine were very similar. Mine required a needle in order to jimmy the latch open rather than tweezers. Invaluable info. Thank you very much!

[@MrSebesta]

Thank you for putting together this very detailed video!!!

[@dunoripavalan1980]

My watch has been resurrected c/o the help of this. Thanks sooo much!

[@alexguu]

I've lost the spring while replacing the battery on my W-93H:) It still works, though there's no sound now.

[@solarsynapse]

Yeah, I think one of the springs contacts the disc speaker on the back cover.

[@thesilent_gamer5137]

Excellent tutorial video. Can I ask, when doing the battery replacement mysrlf. How does this affect the watches 200m water resistance. You hear so many stories about casio sealing their water in a vacuum or a pressure chamber. Replacing the battery myself is something I've avoided doing for fear of ruinning the seal.

[@konradkondi6816]

thanks for the video, it was very helpful with my casio gw-300

[@burlneal6101]

Thanks for your excellent video. You helped me change the battery in my 17 year old Casio G-Shock Atomic watch.

[@jgtn5156]

Change battery GW 300 very good information on how to do this except on the wrist band was different but just exactly what I needed .

[@alvinlowe843]

Excellent video! Wish I had seen it BEFORE changing my battery. Apparently two of the spring immediately fell out and can't be found (or seen). Where can I find replacement springs (that tiny) for my CASIO GW-500A (2688)???

[@CleanClaspCollector]

Great video!! Thanks so much. Revived a 20+ year old GW300 😊

[@solarsynapse]

Might be fun to grab the battery with the metal tweezers. LOL

[@cyberdemigod]

I cannot find a Screwdriver Block anywhere. I really hope they sell them with a replaceable bit slot as well, since I work with many types, like torx, tri wing, etc... But no luck on any site or store :(

[@TEDdotcom]

For first timers, it will be harder than it looks, especially when unlatching the battery cover...

[@Esslinger]

Those are electrical contacts for the alarm and other functions - so if you do not have them installed correctly, your watch might not have some features.

[@plumroseham]

Fantastic video a real watch saver. Just knowing about the battery clip was great. Thank you

[@joepaskowski9091]

Thank you! So detailed yet easy to understand. Worked like charm

[@tgush]

Also should we replace the cover seal with new one or is reusing old one okay. This is original seal, but no visible sign of damage. Did have dirt on outer part of seal but wiped away easily.

[@SeeEssPerez]

Very helpful. Thanks for putting this together.

[@ilike2watch001]

What battery or batteries are used in Casio Protrek watches (eg, PAG240, PRG2500) and do you have instructions and/or video illustrating battery replacement and resetting of these watches?

[@wetenschap123]

At step 8 (6:48) you need to use a needle to open the latch on other models similar to this one. Between the two parts in the video where he uses the tweezer, you might see you need a needle instead. Tweezer are too thick to fit and pull the latch open as seen in this video.

[@handokowibowo8709]

Thank you very much indeed Watch ing from java Street, in java island, Indonesia 🇮🇩

[@147score]

Excellent video, I had problem looking for the battery tab in an old Casio CMD 40 watch and this video helped me getting it opened.

[@Sparks52]

Excellent video. Even though it doesn't cover my specific movement, a 3179, it uses the same rechargeable cell and now I have an idea of what to expect once I have the back off, particularly with the springs, even though things might be arranged a bit differently. I've don't many battery changes, including in a number of Seiko 8F32 movement family perpetuals, which is anything but straightforward. Should be no problem doing one of these now that I know more about the springs in them.

[@fredcalderon5813]

I have a Casio G-Shock G-2300B that uses an ML2016 rechargeable battery. My battery is dead and I would like to replace it, would I follow the same basic steps to replace the cell?

[@dmariscaldc]

Hello guys. Do you how long (in years) do these type of batteries (CTL 1616) tend to last? I have a G-Shock watch which uses this exact battery model. Thanks a lot in advance for your answers.

[@dennisc9467]

I have an old PAG50 Pathfinder. The watch was worn, dipped in water (canoeing) regularly. Worked for about 15 years fine. The recharge capacity dropped dramatically thereafter to the point that the charge would last only about 2 days if not exposed to the sun. I eventually changed the battery. All good again.

[@tonypotter9578]

Very useful re:springs! Thanks

[@rezviali6024]

What a cool old school g-shock

[@davidcollins4227]

Would this be the same procdure for Casio GW9200 Riseman? Also, dont you need to change the rubber gasket o-ring and add some silicon grease to it for waterproof and presure test?

[@Sparks52]

If the gasket and back are undamaged the gasket can easily be reused. There's not much need for silicone grease on it unless you put it into a parts washer or scrubbed it with detergent ;-) The manner in which these watch backs seal is by the pressure placed on them. The deeper you go, the more pressure there is on the back, pushing it against the gasket and making the seal tighter. This is not like having to deal with gaskets on screw down backs that are removed and replaced using a case wrench, which inherently wears on the gasket, sometimes damaging them getting the back off because you're turning the back rim against a gasket that isn't turning with it. The purpose of greasing those gaskets has little to do with making them seal better and everything to do with lubricating it so that the back turning against it won't rip it apart.

[@CoreyBrass]

Woe, woe, woe...anyone doing this needs to apply silicone greese to the back cover gasket before putting the gasket back on. Other then that MASSIVE oversight this was a good video.

[@weareallamericans7358]

Amazing Professional Instructions 🧐👍

[@johnellis2347]

You need to include how to line up back with alarm disc on right spring. Also line screw holes in case and the reason you backturn the screw until it drops in and very important to only snug up or screws will strip out. otherwise good.

[@aland2253]

Awesome. Very helpful. Thank you!

[@fischersfritz328]

NOTE: You have to use the one and only correct word AKKU! The CTL1616 model is an AKKU, not a battery. And only the AKKU is RECHARGEABLE. DL1616, CR1616 are batterys with only one charge and they are never ever rechargeable, but for a wonder, even this batteries works in all the Casio-Solar-Models. Sometimes better then the AKKU'S. ;-) You've got it?

[@Bendc1970A1]

very informative. Hope I don't have to do this for a long time.

[@joaquinelectric1]

becarfull with the springs I lost one but I found it ! I had to use a magnet to find it

[@mauriceroumieux5952]

08/01/2018 Merci bien pour cette présentation qui m'a permis de changer la pile d'une montre CASIO 3319. Cordialement.

[@charleedinegar9060]

Well done; both professionally and well done.

[@jorgeperez3122]

Be carful with the springs !!

[@kdub9918]

I opened the back by just unscrewing the 4 screws on the back but had the wrong battery all 3 springs were in their regular place. I just wonder if i might've bent the spring in the bottom right side when i placed everything back in. It didn't feel like I did,but who knows. In your opinion do you think I ruined the watch by doing it that way? I still need to order a battery and replace it. Just wanted the thoughts of a professional. Thanks in advance.

[@tedryczek3162]

Great video, I should of watched it before I removed the back of the case, I lost the short center spring, the watch still works, where can I buy another spring? Also, I am replacing the band and Bezel after removing the old Bezel, the watch is filthy underneath the Bezel, can I clean it in an ultrasonic jewelry cleaner?

[@jonsmap]

I broke one of the springs. Keen to know if I can get a replacement and where. TIA

[@mohdhidhir893]

hi sir.. my watch model is g-shock gx-56, do you know how to remove the front glass? my watch both front glass has water trap in between the glass. Thanks.

[@flashMXdesigner]

what's a screw drive block? is this some sort of thing you can buy??

[@cybertech1689]

Could not same the normally battery type . CR-2016.

[@markclowe]

That lady's hands are BEAUTIFUL!!!!!!

[@Pimpadeus]

I WAS THINKING THE EXACT SAME THNG!!!! You have excellent taste, Sir!

[@alexsantos3668]

Excelente video, congratulations !!!

[@wildaboutwatches]

Got two springs, but oh dear, I didn't not where they came from..... Even that black rubber sheet doesn't offer clues.PRG 80T, any ideas??

[@TralfazConstruction]

I just replaced the battery on my eleven year-old Casio Pathfinder PAW1500T-7V. Apparently I did everything correctly because the watch sprang to life after I installed the battery. It must have had enough of a charge when shipped after all. It reached the H-symbol indicating a full charge very quickly; inside of two hours.

[@krishnaramlall9451]

Hi I have a question the exact same watch model everything do you get the complete inner part for it to buy I don't know what is the name of the part but the complete part inside

[@vBDKv]

Shouldn't you pressure test it as well to make sure the seals are correctly put in there?

[@markclowe]

How would you do that? If it leaks, you're hosed anyway, right???

[@iso100ful]

ThANK A LOT Super nice pictures You are very generous. 1 million thank from montreal quebec

[@liamsandie]

Do you stock the re seal kit to maintain 200m water resist?

[@albertoperez4731]

hi. Where I can order tools kit?

[@RMontanez3]

Hi I tore this watch down I'm usually very mechanically inclined but I screwed up and removed the movement spring if anyone here can tell me how to get it back in it would be greatly appreciated thnx!

[@Esslinger]

We need more specific watch information - Please include the exact/entire model number or the set of numbers on the back of the watch.

[@awesomeiMike]

thanks, just saved £17:)

[@rickduncan362]

I see the letters CTL before the 1616. Is that a specific battery or can a DL 1616 work?

[@f1k199]

Can you use a cr1616 instead of ctl for my gw 7900b

[@AbdulAziz-ti6hw]

can you help me. .. ihave problem in my watch casio protrek prg550 ... there's no sync between analog and digital time ... until when i set hands on 12

[@pojoksiku]

Perfect video.. even for different gshock type but the same latch with CTL1616 batt. got a little bit confused how to open the latch of the battery. Thank u for a very clear tutorial.

[@johnholland3476]

Wonder what battery goes in the first or second gen casio pathfinder mines been going 8 yrs so far

[@xxdiablogregxx]

How to replace the battery in the GWA 1100, Module 5311?

[@megaman7272]

can we use non rechargable battery? And what can happen if we dont reset the watch after battery replacement? After changing the battery(with non rechargable battery) if the watch does not work, does that mean it is broken down?

[@dennisdorr3529]

Those springs look much larger in this video than they really are. Need a magnifying glass to see the small one.. Video is perfect though.

[@ravishankark4453]

thanks i could not get ctl 1616 so used cr1616 which shd last 2 yrs

[@mihaipopa9414]

Excellent video!

[@jackyha9445]

Anybody have thoughts on putting some dielectric grease around the gasket?

[@djjoep100]

HI DO YOU HAVE TO USE A WATERPROOF GLUE TO THE BACK PLATE TO WATERPROOF THE WATCH ?

[@Esslinger]

Hello, Do NOT use glue on the back of the watch, it will be very difficult to open the watch again. If you are wanting a more waterproof watch, just used the proper parts and tools for repair. I would suggest the use of a light silicone oil on the gasket but never glue.

[@corabird3210]

+Esslinger and Company Thank you.

[@naahalphonsus3954]

my g-shock 2688 model's light went off and is not lighting again but the battery is on H(high).what do i do??????

[@Esslinger]

Sounds like it could be other issues (not battery) You will need to have the watch checked by a service repair shop or send it to Casio for repair.

[@naahalphonsus3954]

any other function works perfectly its just the light but i like the watch so much that i dont want to give it out for them to make it worse for me since there is no casio office here

[@PriaBerkarisma]

can you tell me the watch series.? casio g-shock mtg. ?????

[@cybertech1689]

Approximately 10 years limited . Battery could not be used .

[@TralfazConstruction]

Mine lasted for precisely ten years in my possession. I can't say how long it was in inventory before I bought it. With the new battery I just installed it is theoretically possible that the watch will go on functioning after I'm gone. I was diagnosed with atrial fibrillation recently and I'm 64 years-old and I've done the math. Even when I'm at my most hopeful I don't see myself going another ten years. I'm thinking of giving to one of my younger brothers or designating that it should go to one of them upon my passing. It'll be in my will, that's for sure 😃 . My brothers know about it.

[@Ragnar06]

No need to remove both ends of the watchband. The back of the watch is equally accessible without removing both ends of the band from the watch. That's not my model of watch but I have a better idea how to handle my GW-1200A now.

[@10grandsport]

Excellent video, thanks

[@anandbotak]

Thank you for sharing.

[@RAUFBEDAR]

GOOD 1 THANK YOU VERY MUCH

[@Happy-Me.]

Beautiful Hands!

[@tgush]

What happens if I lost one of the springs. I lost the longer spring.

[@michaelloughlin7108]

excellent video well put together. .....

[@markymark8665]

I’m doing something wrong. When I install the new battery it doesn’t sit flat like the video and instead wants to push up on the strap a bit. This pressure is enough to keep the latch from holding. I may have manhandled it a little too much to release it when removing the battery. I’m trying to revive an old watch I found in the junk drawer. May have to give up and just trash it. It’s a cheap one not the nicer one that’s shown here but the inside looks the same.

[@Happy-Me.]

Excellent

[@naahalphonsus3954]

any other function is working perfectly it's jus the light i dont really know what the problem could be but i like the watch so much that i dont want to give it out and they would make it worse for me since there is no casio office here.

[@Esslinger]

I understand. Can you use it without the light? Could it just be a broken wire or the bulb is out? I do not have parts like that available but if you can do micro-surgery, there could be a chance to fix it by hand :)

There is a slight chance that you have bent the thin metal foil that folds between the push buttons and the metal contacts of the movement. Try gently reseating your movement: paying special attention to each button's spring as you ease it back in :) "Gotta get BACK IN TIME!" - H. Lewis 1984 Cheers!

[@1959Berre]

My son has a G-Shock which he can not use anymore, since the solar charged battery died rather quick after purchase. Finding a replacement battery is tricky. I have been looking for a while, but I gave up.
