How to Fix Your Citizen Eco-Drive Watch | Replace Capacitor

[@williamjames9515]

A battery and a capacitor are two entirely different things. In theory a capacitor should not need replacement just recharging. A battery will die over time. Decide which is which please!

[@WatchWitt]

Yes, I was just trying to over simplify it by using common terms, and I said all three items (capacitor, cell, battery) to cover all bases. This is technically a rechargeable cell. As you said, batteries die and rechargeable cells lose their ability to hold or effectively disperse power vs their new state. But if I said “replace your battery.” one might purchase a standard watch battery, since similar part numbers are printed on them, and ruin their watch. I felt it was important to draw attention to the function of this particular part so that viewers would not miss the importance of replacing this cell with an OEM equivalent, NOT a standard watch battery. Thanks for also drawing attention to it!

Jus got a few of em in the mail and they were in limp mode. Gave em some light and now they're coming alive.. Thank you for the wealth of knowledge. Thanks to you I believe Ill install the batteries myself when the time comes

Cool. Yeah, most people don’t charge long enough, or in direct sunlight. 12 to 15 years seems to be life span.

[@SusieRed]

You are incredible. Do you know you're the only person on KZbin who gave such incredibly detailed instructions? I thought I'd received a bad battery, but I had done just about everything you stated NOT to do while trying to figure out just HOW to put this battery in to my eco watch. THANK YOU THANK YOU THANK YOU! I'm going to place my battery in properly this time and, if it doesn't work, I'll know why and order a new one. That one will be going in just as you instructed and I'm sure will work. Take care and be safe. We need people like you in the world.🤗❤️

[@WatchWitt]

Thanks for the praise. I'm just someone who was faced with the same issue, though. But I did notice there wasn't a good video, so tried to fill the void. If you continue to have issues after replacement, don't rule out that the watch may need servicing. It's a beauty that these cells last so long, but it also means that it's put in years of service. Another reason I mention the part about the caseback gasket, too. Good luck!

[@Vv20vV]

People in the thread, try pulling out the crown & pushing it back in. Sometimes this works as it resets the second increments after/while charging. I purchased a Citizen Skyhawk from Amazon back in 2011. It’s 2024 today & my original capacitor/battery still works fine to this day. This watch has been in & out of rotation for months/years at a time & gets stuck in a drawer at times. I just put it in a window sill & it charges right back up no problems. It ticks in 2-4 sec increments when charging back up. I just pull the crown all the way out & push it back in & it works brand new again no issues.

[@vantrinh5576]

You explain step by step very clearly. Thanks so much for a good video.

[@WatchWitt]

You’re welcome. I hope your Eco-Drive is back in service soon!

[@andrewjones5306]

You might want to change your description, as you say that you WILL be responsible for people's watches.

[@WatchWitt]

Thanks for the heads up…but I don’t see anything in the description that implies that…

[@derrickjohnson5368]

Before you replace the capacitor try putting an adjustable LED LAmp above the watch for a few days and see if it helps. It helped me to charge my Citizen Skyhawk that had not seen light for years. I left an LED Lamp directly above the watch (Maybe an inch above the watch) for 2 days over the weekend at work and when i got back on Monday it was fully charged and held the charge as if it was brand new.

[@WatchWitt]

Absolutely! I tried to convey that, especially in the video description. Most people don't realize it takes DAYS, like you mentioned, to recover from a completely dead state. However, if your watch is 12+ years old, and that doesn't work, then it may be time to replace the capacitor/cell/battery.

[@catsmeow9025]

Thank you, I now know which battery to order! Purchased my watch over 25 years ago for myself for Mother's Day, when I was a single mother! I've now been married 18 years & my husband had it fixed for me (I kept it in my sock drawer, when it stopped working) & wrapped in a beautiful watch box!

Great success on this video! Congrats. 🎈🎉🎊. Great tutorial. I like the tips re: the wood dowel and oil in your hands. I’ve shorted a movement or two via my stupidity. Expensive lessons.

[@WatchWitt]

Thanks! Yes, I guess it was the right video at the right time. @David Schwartz added a great idea of using a plastic baggie between the caseback and the tool, to prevent potential scratching when removing/tightening caseback. I ALWAYS do that now. We’ve all got some uh-oh moments, right?!

[@dougstead1956]

Informative and easy to follow instructional video. Good video and why not save a few $$. It is not rocket science to replace an Eco Drive capacitor/battery.

[@WatchWitt]

Great, I’m glad you thought so...thanks for the compliments!

[@TsukiumisGuy]

Thanks for your video. I had a hard time only because I didn't have any gloves to position the battery when getting it in place. Once I finally got it in, I turned the watch over. Nothing happened but as soon as I got it where bright sunlight hit the dial it started right up. I have it on a window sill right now to get it all charged up. This is a Citizen Garrison Watch I got off Ebay from a seller I used before. It wasn't charging like my other Citizens and when contacted the seller said they had been in storage for a long time. Citizen told me and him that it would take 1 to 2 months for it to fully charge after being in storage that long. Thats way tooooo long. So I ordered a new capacitor off Amazon and thanks to your video its now charging so I can use it. Thanks again.

[@WatchWitt]

Awesome! I LOVE to hear stories like this. Tip: the window sill is great (south facing?) but glass and screens have filters. Direct sunlight outside is the strongest/quickest charge. Check the description for a link to Citizen’s suggested charge times by model/movement. Glad you brought it back to life!

[@garethsigrist8714]

I just bought a Citizen Eco-Drive BJ9130-05E on eBay and it arrived with the dreaded 2 second tick. I assumed it had probably been in a draw or a box for a while so just needed charging but after a few days on the windowsill, it still wouldn’t hold a charge. I googled it and realised I needed to change the capacitor. I then found this video on KZbin and you made the whole process simple with your excellent and easy to follow demonstration.

[@WatchWitt]

The movement number is 6870? A chronograph with 3 sub dials and a date window at the 3 o’clock spot? NOT an Eco-Drive, right?

[@WatchWitt]

I see you edited the comment, changing the movement to 7870. From what I can tell, that movement takes capacitor 295-34. You may also see it listed as 295-3400.

[@AristyanOfficial]

I'm having a really hard time getting the battery. can i use regular type battery? what type??

[@WatchWitt]

Try eBay. No, you can’t use a regular watch battery. It has to be a rechargeable cell…there is a physical difference to it. Another option is to send the watch in to Citizen.

[@AristyanOfficial]

@@WatchWitt very helpful information for me. Thank you for the help.

[@TALKCalgary]

Why would amy manufacturer produce something as stupid as a solar powered watch? Conventional watch batteries are low-cost, available everywhere and easy to install.

[@WatchWitt]

I hear you, but there are also advantages to solar. One thing I can think of off the top of my head, this diver is more likely to keep it's waterproof rating if the caseback only comes off every 12 to 15 years, instead of 6 to 7 times in the same period. Most enthusiasts don't change the caseback gasket.

[@TALKCalgary]

@@WatchWitt Good point. I just can't help but feel that manufactures implement this type of of technology not for the benefit of the consumer but as a form of built-in obsolescence.

Yea many think the light storage battery will last forever but any kind of quartz time piece uses a battery

[@WatchWitt]

Yeah, these will run on light alone, no battery, as long as the dial CONSTANTLY gets light! 😂 But that wouldn’t be very practical. When Citizen first came out with these they claimed to the affect of “never needs a battery,” which I’m sure has created some confusion.

[@WatchWitt]

Once you get your Eco-Drive up and running again, polish her up! kzbin.info/www/bejne/iWeomnWvaZ15h6s

[@freshgino]

Is this 2second ticking normal for a watch I bought brand new just 7 months ago?

[@WatchWitt]

That means you need a recharge. Follow directions for that (HOURS under a light or in direct sunlight) and if it still does it, then this video applies to you too. But be sure to read the recharge directions. Most people aren't aware that it can take days to recharge.

[@stephenoliver1437]

The chargeable battery in most solar powered watch have a service life of about five plus years they do not last for ever logic sense like a vehicle rechargeable battery same principle

[@WatchWitt]

The original gen of Eco-Drive, which the watch in the video is, are getting about 12 to 15 years of life. I hear that more recent generations are expected to outlive that. Some of the confusion about these watches is that Citizen claimed the watch "never needs a battery," or has a "lifetime battery," etc. But, as you mentioned, that's simply not the case!

I received my Citizen Eco Drive J850 PRT a couple of days ago, it has Power Reserve Indicator but it always shows to zero, although the watch works fine except of that indicator. If I will replace the capacitor or battery is that going to fix the indicator?

[@WatchWitt]

Nice watch! Well, a couple of questions to get the right answer for you. Is this a new or used watch? If new, did it come with the crown pulled out so the watch was stopped, or was it ticking? 1 sec increments or 2? I’ll start by assuming it’s new and you opened it from the box and just started wearing it. Just keep wearing it and constantly exposing it to light and that power reserve meter should slowing start rising. If the battery were dead and/or to give you an idea of how much light it takes to recharge the cell, it takes 25 straight hours of the dial 8 inches away from a 30watt fluorescent light to have it start working normally. 200 hours to completely recharge. What kind of light have you exposed it to and for how long?

[@koling-koling3938]

@@WatchWitt Hi and thanks for replying. The watch is new and the crown was pulled out first time I got it out from it's box. The second hand jumps in 2-second intervals in the first time the watch was exposed to room light. I exposed the watch to different sources of light (outdoors for couple of hours and room light entire night). Now the watch works fine and keeps up with time just the Power Indicator is dead. I have ordered a replacement of the battery or capacitor from amazon and I'm not sure if this is going to fix the issue.

[@WatchWitt]

@@koling-koling3938 Ah, ok. Well, based on your answer, I feel that it just needs a longer charge time and I think you’ll see the power reserve meter start to increase. I would recommend a mixture of direct sunlight (outside, not through window) and constant close proximity indoor light for that 200 hour range. That’s 8 days! If you get some solid sunny outdoor time it will reduce that charge time, though. It does sound strange that your new battery would give off the 2 second tick warning, though. If it doesn’t improve after doing the above, I would return it. It sounds like that’s not an option for you since you already bought a new capacitor for it. So, that would be the next logical step if you can’t return it or utilize warranty service for some reason. Good luck! I hope you’ll report back here with the outcome so we can all follow along!

Thanks for this video. I'm looking to replace the cell in my Eco-Drive. However, mine doesn't have any notches on the cover. Any ideas on how to remove it?

[@WatchWitt]

Hard to say, as there are a few different caseback styles. If you have series of small ridges around the caseback perimeter (almost look like a grip for your fingers to rotate it) then you need a friction ball. Or, if you see a little lip, almost like a screwdriver head, near one of the lugs...that's a snap on/off caseback. You pry/leverage that carefully to remove. But caution with those...they can be extremely difficult to put back ON without the right tools, and you risk damaging your watch...many will shatter their crystal while attempting.

[@stevenmonkman1500]

I did a little more research and found out it is a monocoque case GN-4W-UL. Apparently, the bezel needs to be removed and the stem to replace the battery. I would love to see a video on that!

[@WatchWitt]

@stevenmonkman1500 Oh, wow, I've never seen a monoblock case from Citizen. Yes, typically you have to remove the crystal and go in from the front!

[@WatchWitt]

Yes, it can be difficult to source the right part. There are many vendors on eBay, if you can search your watch model number, not the movement number. Eslinger and Cousins are great resources too. Watchmakers will generally order these in bulk, in various sizes and thickness, and match up using the old gasket as a template. Good luck!

Any help on diagnosing the problem on my watch. It's j810 caliber Citizen. The problem is that the watch doesn't show the battery is discharged. The second hand is ticking normally. After leaving the watch overnight it stops and gives me the incorrect time the next morning. The watch is only a few months old and I haven't changed the battery. It's my understanding that these eco-drive movements can work for over 6 months in total darkness. Great video btw.

[@WatchWitt]

Yeah, that’s weird. Definitely doesn’t seem right. You may have a problem with the movement, such as resistance that is draining the cell more rapidly, so you never SEE the 2 second ticks. But that’s a long shot. Does it keep perfect time in the day, when you’re wearing it? If so, I would suggest trying a deep charge. If you can’t get it OUTSIDE in direct sunlight for 12 hours, do an indoor lamp for 3 to 4 DAYS. If that fails, I would pull a warranty claim on it.

[@rjohnsoneod]

Thanks, I take a couple watches (G-shock mudmasters) into the jewelry store, for battery replacement. For some reason the tech at the Jewelry store did not work on these watches but they have someone that they send some watches to. The staring price for battery/capacitor replacement was $125. The capacitor and the watch repair kit added up to less than $30 (I will also replace the gasket based on your recommendation). But while my citizen was more expensive it is still kind of a basic watch with no special features and I should be able to replace the batter/capacitor. Your video was very helpful. Thanks for your video. Sorry for all the trolls trying to give you a class on battery vs capacitor. Your video was fine. Order the right part in the first place and you don't have to worry about putting a battery where a capacitor should be. Regardless of what I am working on, I always check my parts across several websites to make sure it is the right one. I like the part about wearing gloves. That is my down fall. I get into the repair and forget to put on the gloves laying next to me.

[@WatchWitt]

Yes, it's expensive, but definitely worth it for those that aren't comfortable doing the replacement themselves. I mean, you're going to get another 10 to 15 years out of it!

Any suggestions for a good place to buy replacement gaskets? I have a similar Citizen watch, E870 movement. I am having a hard time finding a gasket. Figure I might as well change it while replacing the battery.

[@WatchWitt]

It IS a good idea to replace the gasket, because at 12 to 15 year battery life, it's a pretty good chance you're the first one crackin' that case open. Esslinger is always a good resource in the States, or Cousins in the UK. You can also find random eBay sellers.

The watch seems to function normally, but the second hand is stuck at :52 and even when I orrsstthe function buttons to make it go around it does nothing. Is there a solution?

My initial thought is that you haven’t re-charged it enough. It takes HOURS (days!) when bringing back to life from full stoppage. So, I would try that first. Direct sunlight outside if you can, instead of through a window. But, it may need service. Let us know the outcome!

Well, I’m hearing 12 to 15 years for Eco-Drive…definitely not “the life of the watch,” like they first mentioned! Some traditional batteries are 10 year, but depends on the movement for that rating.

[@bc454irocz89]

@@WatchWitt mine is only 3.5 years and already dead. Dissapointed with the watch.. The bracelet is very cheap as well

Very cool and very helpful, you make it look so easy!

[@WatchWitt]

Thanks! It’s fairly easy if you’re comfortable with the tools and process. If not, it’s well worth the price, as expensive as it may seem, to have a professional perform the work. If the watch means anything to you, it would be a shame to ruin it!

Sweet! Love a great Eco-Drive.

[@Penelope-rosa]

Never thought the eco drive had a battery. That was why mine stopped working. 😅

[@WatchWitt]

Many of them stop after living in a drawer or other dark spot, then people don’t recharge them long enough to revive. If yours is in the 12 to 15 year range, the rechargeable cell probably needs replacing. If it’s newer you might be able to bring it back to life!

[@TerenceHughes4501]

I'd pop the crown and stem out as well while the backs off and replace the crown gasket

[@WatchWitt]

Good move!

[@mellsterr6192]

Thank you! I bought my Skyhawk in June 2002 after transitioning from the C-141A/B to the C-17A. Stored the watch for the last 10 years in my top drawer. I was wearing a Breitling Areospace. Digging thru the drawer, I found my Skyhawk. Deader than a door nail. Trying to revive it. So far no luck. Any ideas?

[@WatchWitt]

If you can put it OUTSIDE in direct sunlight (not in a window sill) that's the best bet. If you must charge through a window, it will take longer. But these can take 30+ hours of recharge to revive.

[@svrider31]

It needs to be reset. You can find out how right here on KZbin.

[@polishguywithhardtospellna8227]

Thanks a lot

[@WatchWitt]

You're welcome...hope it works out for you!

[@jcbmax1]

Ok so any way to correct the second hand-time marker alignment?

[@WatchWitt]

Nope. That’s just part of the design fit and finish. It’s tough to find a budget quartz, and sometimes even fairly expensive watches, that hit every second marker. If you think it’s worse than it was, you could shutdown the watch, remove the seconds hand and replace it being careful to line it up with any particular second marker. Good luck!

[@seanguthrie5162]

Brass; not bronze!! Most electrical connections of that type are brass. Bronze is almost never used in electrical connections due to its brittleness.

[@WatchWitt]

Absolutely! I meant to say “bronze colored” as a reference point for the part. I hadn’t even thought about the electrical connection aspect. Sometimes keeping it simple is too vague!

[@mdunawaym]

The girl at my watch shop said to first try pulling the crown out to the time reset position, and try charging it that way before battery replacement.

[@WatchWitt]

Absolutely. This video is if you have to go to the next step. Also, most people underestimate how long it takes to get a full charge from dead stop/empty and/or don’t position under a strong enough light source.

[@mardukl]

damn, thanks a lot, my watch is just stopping to work at night, so i assume its the "battery" cheers its a citizen wr-100.. was my dad watch.. its sentimental value

Don't forget to recplace your gasket while you're at it.

[@WatchWitt]

Agreed! I mentioned at least inspecting it, but these will be old gaskets!

[@wd2862]

You are so welcome! Thanks for watching, and I hope you get many more years out of your Eco-Drive!

[@jimg518]

Glad I saw this. My Skyhawk AT is 11 years old now and I’ve been thinking about this day coming for my watch. So far so good though. But I feel good about doing it myself when the time comes. I’ll pick up that tool kit too. Great video. Subbed. 👍🏻

[@WatchWitt]

Thanks Jim…glad you’re still getting a long 1st life out of your Eco-Drive!

[@SBC581]

Great instructions! I followed the instructions from the link. I didn’t need a new battery. The recharging time from zero for my watch is 36-70 hours and direct sunlight outside is best. My 20 year old watch is running again.

[@WatchWitt]

Great news! Yes, most people grossly underestimate the time needed from complete stoppage to full charge. And outside is best, if you can do it…windows and screens filter sunlight. Thanks for leaving this comment!

[@michaelpreston3819]

would this happen on a new watch? thats whats currently happening with mine.

[@WatchWitt]

It could, but not likely a bad capacitor unless you bought really old new stock. Charge it in direct sunlight (outside, not through a window) for the best charge rate/effect. Read your movement’s charge rate, but most are 12 hours from empty to full in direct/outside sunlight. 150 hours charge empty to full 8” from a 30w fluorescent bulb.

[@travisjones780]

Jewelry store quoted me $120 for this repair. Thank you for the tutorial.

[@WatchWitt]

You're welcome! For some people that jewelry store repair is the right thing to do. For others, this is a better move.

[@larryfromwisconsin9970]

I have changed the capacitors on two different Eco-drive watches, one a Nighthawk. Both were over 15 years old.

[@WatchWitt]

Great to hear, Larry! From the popularity of this video, it would seem many of the early generation models are due for a switch out.

[@salvita64]

Mine it’s 21 years old and going strong! What about the waterproofing ? Is it there a way to do it your self ?

[@WatchWitt]

Nice! That’s a great service life! As to the waterproofing, just replacing the gasket that I mentioned and showed towards the end would be all you need to do. But if your caseback has never been opened, and you don’t have any signs of fogging inside the crystal, I would just leave it be.

[@Rubbernuts234]

Should I recharge with a led lamp or a actual lamp with a bulb

[@WatchWitt]

Either is fine, but direct sunlight is best…meaning outside, not through a window which have UV coatings and/or screens that filter light. Check your movement number recharge instructions for recharge time.

[@swingmanic]

A piece of sellotape stuck to the back with a tiny bit sticking up is handy when unscrewing the back.

[@WatchWitt]

Yes! Excellent tip. Thanks for sharing!

[@plamen6969]

Thank you for the informative video. Couple of months ago I broke the crystal on my eco drive and small fragments of the glass entered the movement preventing it to work correctly causing the second hand to move in two seconds increment. I took it to a repair shop and they cleaned up the watch and put a new crystal. Three months later I noticed the second hand moving in two seconds increment again ( I have changed he capacitor recently- not the cause) and when I looked at it closely under a microscope, I saw another small glass fragment stuck between the movement and the case, which tells me there are more pieces hiding inside. My question is, how to remove the stem and crown to clean it up thoroughly? Is that stem removable at all and how do I do it? Any advice will be much appreciated. My movement looks similar to the one on your video. To be more precise, the movement is N-E100 K54594-Y. Thanks in advance.

[@WatchWitt]

Well, unless you actually SEE more fragments, or the movement is erratic, I would leave it alone. Chances are that’s just one piece they missed. They would have taken out the movement completely and checked for debris, since that’s what the watch was in for. But, I’m not sure where the exact stem release button is on your movement, or mine, but it’s likely the button/hole with the arrow pointing to it. If not, it may be any of the raised buttons near the pathway of the stem. Be gentle. You can damage the movement if you press the wrong part! Also, there’s a good chance you’ll get dust/particles/lent/debris between the dial and the crystal unless you have an air puffer before reassembling. Let us know what you ended up doing!

[@garyhuber5069]

Witt, great video and easy to follow. Found the correct cap, but where can I purchase a gasket for the back cover?

[@WatchWitt]

Thanks! Esslinger is a great resource for parts, but determining which gasket you need can be a little tricky. You may end up stocking up on several sizes!

[@RampartPh]

Very informative. Great idea w/ the cuticle pusher. Thanks

[@WatchWitt]

Thanks for watching…glad you got some ideas out of it!

[@theftworthrealtor]

I have this exact watch but the case back is smooth, no notches for a tool like you show to grab and turn. How would I get a smooth case back open? I was thinking maybe it’s a tool that uses friction to allow you to turn the case loose…a point in the right direction would be greatly appreciated.

[@WatchWitt]

That’s weird since it’s the exact same watch. I can’t imagine it’s a snap on case back, but look for a groove or lip for tool prying leverage. More likely that, as you say, you need a friction ball caseback remover. $8 for a cheapy, $13 for a quality Bergeon.

[@theftworthrealtor]

@@WatchWitt thank you for the reply, I looked all around and it's totally smooth, no lip or groove at all where a prying tool can be used...will have to see if I can find a friction ball as you mention...

Quit calling it a battery.

[@WatchWitt]

I agree with you, but was trying to simplify the instructions for the audience. I called it all three; battery, capacitor, rechargeable cell.

[@Spurdospaerde692]

Why? It is a battery. A manganese-titanium rechargeable lithium battery, to be precise. It's not a "capacitor". One or several of those are however used to charge this battery, so I thought this would be a video of a more advanced repair procedure than a simple battery replacement.

[@WatchWitt]

Can’t please everyone. Most non-watch enthusiasts believe this is a magic, completely solar powered watch. The goal of the video was to educate that there IS something inside that holds a charge, 1) it doesn’t last a lifetime and 2) is easy to replace, much like a traditional watch battery. See pinned comment at top, too. I pinned it to bring attention to those that may want to debate or hear where I was coming from.

@@TedCornish Exactly. They wanted to be able to say “never needs a battery.” Did they bank on consumers throwing the watch out at the end of battery life, and then buying ANOTHER Citizen? I think they did, but I also like to think that companies don’t have evil plots like that! It seems they just don’t want to back step on their previously mentioned marketing slogan. Eco-Drives are great watches, but it takes folks like us to inform the consumer.

Oh! Well, did you try bringing it back to life with the recharge instructions (timeline) from your watch/movement? I have a link in the description. But they take WAY longer to revive from complete stoppage. Like 18hours plus in direct sunlight. Longer if that’s through a window. If it doesn’t come back after that, I’d start with a new capacitor. If that doesn’t do the trick, then it may need service. If you love the watch, and the above doesn’t sound like a good time…just send it in! Me, I like to tinker.

Sometimes a jeweler is a watchmaker, and sometimes they aren’t. You can source aftermarket hands, if not from Citizen. Depends on your dial and movement, and what kind of hands you’re looking for.
