I thought I had a dead watch! This video saved me, I set the watch on a LED flashlight for a few minutes and it's back on! I had even tried putting it in a window before and it didn't work. Thank you!!!!

I have a different type of Casio watch, but leaving it in the cupboard for a couple of years, I was sure it wouldn't start again. I've left it near a LED lamp as you suggested and in a few hours it just resurrected! Thank you for sharing this tip!

Just bought the exact same watch brand new on clearance for $25 at Wally World. Pretty happy about that. First watch purchase in decades. First G Shock also. Cool watch!

Great info. I didn't even know my watch was solared powered. I thought I needed a new battery. The watch was a gift. Lol. Thanks

Thank you for this. I have a GW-810BD that i put in a drawer years ago as I thought it was broken. Found it again today and after following your advice it is working again.

Thank you for this video. I had mine out on the window sill all day yesterday and nothing. I have a similar light to yours and put it under there for 1.5 hours and it sprang willingly back to life. Much appreciated.

Great and informative video! I got a GW-7900-1ER that has been sitting in my drawer as I've been wearing other watches for a long time. Took it out today, and found that the charge had run out. While I was watching this video I set it under a LED light, and got it to the CHG-state. Sadly, it's quite cloudy outside so I guess it will take a couple of hours before the charge gets to a higher level.

This was a really cool video. I now know how to approach this situation if any of my g-shocks loses power and goes blank. Thank you 😃👍

Thanks 😂 for valuable information 👍 I was able to finally charge & set my solar/atomic GW-700BDJ ⌚️

I just bought a GWM530A-1CR and it was completely dead. Thanks for the heads up!

Thank you so much.. I got a watch from a good friend's girlfriend after he passed away. Thought it was broken. Put it under my solor light after trying it on the window for a day without any results. And it started working immediately.. Thank you so much.

Thanks for the good video. My newly purchased Edifice EDQ1000 Tough Solar needed FOUR DAYS on the window sill to get past the "low charge" message. You need to be patient.

Love this watch, bought my chrome version in 2010, still going strong with little use the 10 year battery is chugging right along. Love how this watch goes to sleep to save power.

Glad I stumbled on this, tried all kinds of button presses. Daylight. Kitchen light. Nothing would work. Fairly new watch too. Two hours under LED torch and it is back working. Thank you.

LOL this just happened to me a few minutes ago. I immediately ordered a replacement and put the watch near my brightest lamp. I might as well try to revive it. After about 20 minutes I look over to the watch, screen blank. 30 minutes i look over and the numbers finally show themselves! I cancelled my replacement order. Not sure how long it will take to charge up to "High". I assume it will need a long charge after that deep sleep. I really enjoy this watch so I will hunt for the rest of em.

This model was the very first G-shock I ever owned. It was a gift for my sister and I wore it for abt 6 years before I realized hey, there are other models

Thanks. I got a G-shock as a present many years ago and it has sat unused in the original box in a cupboard for years. Thought I had to replace the battery, but seems like it has revived to the minimum 'level 4' battery state with 15 mins under a desk lamp. Guess I'll leave outside for a bit to get it fully juiced up. Well I ordered a new battery for it already - I'll keep that as a spare incase the original doesn't hold up.

Thank you for this. Mine went dead after sitting in a drawer forever and when the time came up the buttons don't work. This makes sense now.

My carbon fiber gshock just came turned off and I was freaking out thank you for this video

Thanks for the heads up. I just ordered one of those in all black and it’s my first atomic watch.

I bought a Bering solar recently and was amazed when it started to tick at 2 second increments as soon as I unboxed it, took around 4 hours in a dimly lt room in the evening to change to running normally with one secong increments showing it had a bit of charge in it's Li ion battery. The instructions say it will need 24 hours in full sunlight to reach maximum charge so I've booked a holiday in Gran Canaria just to make sure

Just got mine brand spanking new, placed it near an led light buld and there you go! Started working! Thanks! 😀

3 years in my chest of drawers though watch was dead. put it into the ceiing light for 5 mins its working again! woohoo!

2hours of charging for 6 months is very nice. But i dont recomment to do it this way. Solar watches are made for slowcharging over time. Just wear it. Normal light will keep it filled up. Sure if it is dead you need a deep charge. But for normal use. Just wear it. 2hour=6monthes. 5min of sun per day is more then enough to keep it going for ever. Little bit longer if only inside light. But it plenty enough.

Great taste I also went with the metallic blue model.

I have the blue Casio 3405 in this video, great watch but I haven’t been out much during the day lately so it hasn’t gotten sunlight recent and has been constantly dead, when I first got the watch I worked outside and the battery was always on “high”. I didn’t know it was a capacitor and not a battery. Good information, nice video!

Thanks for you help, I had an Edifice that was sat in the draw for a while waiting to be repaired (2 years i know its a long time) I used a fairly strong headtorch and after about 15 mins it started up again I thought i'd comment incase anyone was in a similar position as myself. Thank again you've saved me £££.

They should put solar watches in clear plastic packaging, so they get at least some light while stored as stock. They’d still be in the dark when shipped, but it’d be far better for the watches.

Thank you very much ..my rang man just came out of the box totally blank it’s dark outside so I’m using a led 💡 .Thank you very much... it’s my second solar powered watch.. The first one came out of the box fully charged...

I recently got a Ti Square and the watch was dead out of the box, I kept it under a room fluorescent light for about 10 hours and nothing happened. After seeing this video, I decided to use my iPhone's torch (led flashlight) on full intensity about 2 inch away from the watch face and within an hour the watch started working. I guess keeping the watch in bright sun would've worked as well but the sun here in middle east during summer is something else and might damage the watch due to extreme heat. So, this was very helpful. Thank you :).

Thank you so much! Was worried my watch was broken, haha

Thank you very much! I’ve got mine charging right now on my pellet smoker outside. I will set a timer on my iPhone for 2 hours from now and recheck the watch to see what it’s doing.

Thanks for a great video. I have the same model G shock watch, about 10 years old now, wonderful watch. Recently it has gone blank in the winter season, needing south window time to recharge. I guess it’s new battery / capacitor time.

Definitely time consuming to revive depleted batteries under such circumstances, as it takes very long time to progress from one power level to the other. Especially at medium level, depending on available light intensity, it may take a full day or to just to reach high level... Meanwhile subjecting the watch under prolonged direct sunlight or other similar outdoor condition is detrimental to the watch chassis as UV ray exposure will accelerate aging/degradation on the resin and other plastic parts in the long run, besides building up heat on the module under charging... IMO for quicker revival of depleted batteries a compact, high power photo/video LED light panel may help. Just let the timepieces concerned rest on the panel for ~45-60 minutes and set the panel's intensity to 45-55% (you don't want the LED panel to become too warm during its own discharge). Repeat the process for a few nights and hopefully the power will be restored to high (or near full). Do also note that under such charging conditions there will be false power level indications, so when the battery indicator reads high, do not remove the watch but let it sit a bit longer.

I wanted to get my gshock for antrip tomorrow and found it to be dead. Thanks for the informative video. Its woken up now bit none of the button can work so i propped ot next to a loght source and see what happens in a hour or 2. But the way my watch its the gx-561jr orange. Cheers.

What a great channel! I like your relaxing style. 👍🏽👍🏽

Thanks for this. I was about to send my Casio Sport tough solar to a dealer. I put a bright flashlight on it an immediately it came to life. I have it charging now. Great video!

You really produce some really nice videos.

Thanks Dave , pro trek up and running again.

Casio solar can’t be beat by anyone period

Woo Hoo. Just revived my Pro Trek 3258. Thank you very much.

Thank you. Followed your advice and I have my watch back working as well as it did. I'm so pleased.

Just saved me a trip to he watch shop, will give this a go....

Thanks Greg your the go to guy I watch for casio watches was in panic mode with the purchase of my gw2310 totally died when received watched your input on said watch saved a return thanks buddy

I have a G-Shock, different model mine has dial hands, and it quit last night with the hands at midnight. But it hasn't been in a lot of sun lately mostly just artificial light in the house. So I set it out in a sunny area of the house we will see if it comes back to life tomorrow! I will report back. I have another solar watch that i hardly wear (it's fancy) which continues to work but I always leave that one where it gets at least an hour of sun a day. It is still ticking.

Dude thank you so much, I got my Seiko Solar Chronograph working again using this method after years of being in a box. A new battery (capacitor) was going to cost me 60 + bucks TY TY :) Not even ten minutes :)

Thanks for the video as my baby g touch solar literally died too cause of lockdowns and not being about to go out for the a daily charge

*_Man I can't believe that you managed to get a calibrated reception @ _**_13:00_**_ in the afternoon. I wouldn't even assay such a thing, ere sunset, living nigh a military base. No way!!_*

Thanks so much for this. I bought a used watch and received it in a non functional state, but this video helped me out!

Great info. I have one coming soon, so now I'm prepared.

You've got some great content for a great watch brand! I enjoy and have learned a great deal from your videos, and thinking about getting a couple of watches seen in your collection. I've seen a review or two similarly that said something about a battery being dead or not working, one guy said he had 2-3 of these expensive batteries changed out (don't remember the exact situation / content, and possibly other brand of watch?), glad I didn't fall to the immediate panic before seeing your video.

Very informative. Thanks. Think they’ll ever make a blacked out version with a negative display for the gwm500/530? That would be pretty cool!

I reckon a watch will sit in a box for 6 months or so on average after it leaves the factory until it is purchased (some might only wait a few weeks, some might go a year or longer). And it was probably not fully charged before being boxed, nor was the power save turned on by default.

Great review

Good stuff! My square tough solar has been blinking low lately. I thought one decent exposure to sun for a few hours should bring it back for a very long time? Also I don’t know why just because it was face down in the dark for a few days it should go all the way down to low. I thought these watches last for even up to two years on a single charge? I’m going to try to get it back up to high level and see how long it lasts. If you have any suggestions or you think it’s cause for concern please let me know. Thanks 🙏

BTW it really is a rechargeable chrome titanium lithium cell (CTL 1616) that indeed has battery charge/discharge characteristics. Its by far not a capacitor! I don't know why people use this utterly wrong terminology that constitutes false information.

Informative, interesting and well thought out presentation. Thank you!

Thank you, but the battery on my Tough Solar Casio doesn't want to fully charge. I was thinking of taking it off and give it a reverse charge of the same voltage it is designed to receive. This will most probably revive it. Regards.

Thank you so much, I almost want to throw it out before I found your video

According to the Casio manual, it clearly states to leave the watch under direct sunlight on the dash of a vehicle for a full 72 hours of direct sunlight if watch has been fully discharged, and 96 hours with cloudy day.

I have this very same watch in the black bezel version. Recently I got a different used solar G-shock, it arrived half charged so I put it outside on the window sill, but after several hours it remained half charged. The next day I left it outside all day and was starting to worry as it was still not fully charged at night. So I left it out and was relieved to finally see it on full charge the next morning. Every watch is different so just be aware that mine took about 2 full days outside in the sun and that was just going from half to full charge. Also I did feel it was pretty hot when I took it in so if that's a concern then it may be better to charge indoors under a light.

Brasil. Oi. Ótimo vídeo. Uma dica para reativar relógio solar...deixar próximo lâmpada led por umas horas. Sem calor, sem tempo ruim. Legal!

I got the grey one from walmart...the circle thingies for the time is vertical on the left...i started to watch this juat now to see the opening of the back door...i wanna see how to open it...i am surprised you are saying its a cap...witch i belive it.

Hi. I got another tips. Im using the iphone torchlight..keep doing it about 2min and your gshock tough solar should charge. My watch dead almost a year.

thanks! simple and to the point. got my s1100 up and going.

Good video. I’m getting a gxw56 soon so I will remember this advice thanks!

I have a similar Casio solar watch that is 9 years old and is still dead after 10 minutes under an artificial light like yours…. Will continue charging and hope it wakens eventually…..

At about 1:18 into the video you say that "people" have told you that the watch uses a capacitor rather than a battery to store the charge being generated by the solar cell. I don't know where these people are getting their info or why you believe them. All the info that Casio provides indicates that it is a battery - specifically a CTL1616 Rechargeable Watch Battery. There are other KZfaq videos about how to replace it, although that should not normally be necessary.

My 30th anniversary frogman i having similar issue. There is just a blinking something at the bottom, but no other display whatsoever. Trying that LED trick now. Please pray for me.

you had a ghost run by at 1:37

oddly short charging times.... all my watches take hrs upon hrs... and I think that my old version of Rangeman from empty to full takes 72hrs in sunlight.m

Sadly different experience. After 10 years my one went first totally empty. I was charging 2 times on direct sunlight, went up to full charge,but after few hours it was dead again and again. Now I have ordered a new battery.... It's just a lítium battery. Which doesn't like full discharge at all. If it's new, maybe will work after a good charge. But an old 10 years old, like mine just died.

Such a great channel…thanks for this

The idea of a solar watch is that you can charge it with free energy from the sun. Charging it with a lamp and electricity is not very renewable, neither cost effective. The voltage of a solar cell depends directly on the brightness of the light source. Using a flashlight for charging is pointless. The light outside is 100 times brighter than the brightest electrical lamp. It might be enough to kick start the battery, but charging with a LED light would take months. Just use your watch outdoors, that is what it is designed for. If you don't use it, put it on a desk but not in a drawer.

I have the same watch just black and I left it in my window I don’t think it is enough light I might have to wear it outside but g shock have some great ass watchs

Dang, watched many videos on this channel but now i saw a missed huge missed opportunity what made me comment @ 01:19: If there is a working watch, why you put a third one there??? (little lol from my side :) )

I hope that you'll get your radio tower back up again, otherwise you'll have to use the app. for receiving the signal. I don't get why the big brands like Seiko, Citizen and Casio don't make more of a statement about this. I'am lucky to have great reception in the Netherlands.

I don't see why you didn't read the user manual for the atomic time. It says clearly that you first have to do a manual connection before it can automatically.

Just about to do the same with a PRG250, myself!

I’ve got the g shock full metal, and it just goes to low so quick, it charges fast but it’s annoying l how fast it drops

ok cool. Just bought G-shock solar watch (Gw6900). It flashing "CHG" and no indication of battery(even LOW is blank). it displays time but none of buttons are working. I guess it is time to buy a new rechargeable battery..

I tried charging my tough solar gst series inside the car where sun burst hot suddenly all lcd becomes black and after it gets cold it comes back to normal and fully charge. True gshocks are made tough hot cold vibration magnets.

Can this work even though the watch has been dead for years?

same here, not try to see how long it takes for mine to recover..:)

Very very helpful! Thank you so much!!

Got a Casio Ràngeman 9400, completely dead , left it out 12 hours ,bright sunlight ,oñly got to low battery mode, same again next day ,only reached med battery mode , one press of the light button and it's flashing low again . Devastated

Put my mudmaster in the dark for 30 days it hasn't worked since. Leave it in sunlight for a week or so and it goes dead again five minutes after walking in the house

I literally just opened the exact same watch fresh from the post. No power... no problem just follow your handy video and feed it some photonic energy. (t+20 and nothing yet) One issue though, the watch is on the last hole on my wrist. My absolute favourite g-shock had a Casio version of a NATO band with a plastic spring buckle. got wet... Do they make a NATO style band for the smaller watches like this one? Also the Blue version you have is very sharp but seems to be out of production. lame. Thanks for the video!

Just got the same watch but in silver

Wow very informative! Awesome and rt to the point. Thank you !

I bought a Seiko solar watch for about $400 and it stopped working after about 2 years. I tried recharging it with a bright LED light and it quit working after a few hours. I put it in a drawer and went back to my 30-year-old Bulova which keeps time almost perfectly as long as I change the battery every few years. I finally took my Seiko back to a watchmaker and they CHANGED the batter for $100. The watch once again stopped working after a few days. So now I'm taking it back to the watchmaker and they're going to properly charge the battery. It's probably because my Seiko watch was sitting in a dark drawer for a couple of years and lost its charge. It took me all this time to figure out the problem. The people who sell these watches should advise the buyer how to properly charge the battery (capacitor) or charge it themselves, even if the buyer has to come back to pick it up. By the time my watch stopped working the warranty had expired.

My g shock king of g lasted only 2 years to be exact....damn

I've left my eco drives out in the garden some times, some modern glazing with protection even restricts the usable light,my daughter's new bedroom has 2019 glazing and she is adamant that her calculator goes flat quicker despite the new room recieving more sunlight hours and that if she places it outside on the sill it charges quicker,worth remembering.

Hey good job on this information! Thanks!!!

Great video!

Just got two of them.

worht to mention is that a Cool White Light Source is mor effective than a Warm White for example

Good day sir,i bought a second hand touch solar from Japan surplus,seller tell me that in Japan they remove the battery before shipping,im from Philippines,and when i bought it,i replaced it a mew CTL1616 battery,but ofter,it did not charges,now its been 3day,still i connot use all button, please help, Gshock GW 2310fb, negative display, thank you sir

Thank you Greg:)

Darn.. I thought this was going to save my GW-530a.. I followed these processes as well as other online help sections but with a brand new (proper Panasonic lithium battery) my watch is not resetting itself and my buttons don’t do anything after the back is installed. Before the back is reinstalled-the buttons offer some response-and the backlight works.. but within seconds of installing the back cover and while screwing it on-the watch makes an audible “beep” and I can’t make any inputs.. any guidance?
