7. Battery replacement: Eco-drive Nighthawk TITANIUM - Will this tick again?

[@keithwwalker]

Thanks, my favorite watch too! My battery lasted 20 years! Here's to another 20!

[@Iknowrealtv]

Am I the only one that start slow clapping and cheering the nighthawk is back. low key a tear almost came down my face.

[@edardonn2053]

How much you paid for the battery and where to buy it...thanks in advance

[@floydburkett2749]

IknowrealTV if you are a jeweler you can usually buy replacement parts directly from watch companies. If your not good luck. Allot of watch companies will not sell parts to non business entities. At least that's the way it works in the u.s . i repair watches as a hobby. You could try esslinger.com . they sell generic parts and are widely popular and reliable amongst people who perform repairs. Its best to purchase in large quantities and varied sizes when it comes to parts. At least for me its cost effective.

[@gibbyh65]

ive seen them on ebay, theyre called capacitors when you look them up, fairly cheap, 15 bucks for my promaster..

[@escaragami]

WOW, what a great production and music. I had to watch it twice because I was distracted by the show. Thank you for the instructional too.

[@exxonrcg]

wow that was easy. fun vid. I had reservations on these eco-drives being harder to replace than normal batteries. This changes my mind

[@freshlifeline]

I'm surprised you don't have a lot of subscribers. This video is very helpful.

[@nightlore000]

My eco drive watch .. I bought in 2000 .. 23 years old .. same battery ..

[@Bob1942ful]

Amazing video. Learned more from this video than I did from the ones where people blather on and on about things that are not important to the subject. And as another reviewer pointed out I to was moved to clap while shedding a tear of joy.

[@andrebark]

Awesome! Your video saved me!

[@BixbyConsequence]

Hmm, 5 years is pretty short. It's a long-life battery should last closer to 20 years. Storing in a dark place and allowing the battery to run down will wear the battery prematurely. Make sure to wear occasionally, or store in such a way that there's enough light to keep the cell charged.

[@keithwwalker]

Mine lasted >20 years, its a watch for wearing!

[@markwietstock1537]

Guess I'm a little late to the party, but thanks for this video ... clever, funny, and great info for any DIY'ers considering replacement of their Eco-drive batteries, rather than just "deep-sixing" a favorite watch.

[@t-sun-6980]

Does your nighthawk have alarm sound?

[@Easy_Victor]

After trying to charge a newly acquired piece. I need to change the capacitor/battery. It will not hold charge. How tight is this battery cover? Any tips on unscrewing it? It’s really on there tight.

[@testtesttest1803]

I have one. How long have you been using the watch...?

[@bluebump]

hello my watch model BN0150 but I can't find the battery. Where can I find the battery number?

[@didietz]

What is the actual type of battery? , I'm googling on it and it has many types

[@borjaosaba4412]

Hello. Thank you very much for this video. One question please: What is the meaning of 10U in the box of the battery??? 295 - 5600 - 10U. Thank you very much.

[@tcwhite0104]

OMG had me laughing the whole time, the way you flicked the instructions away!! LMAO..anyway I have the same watch and I was about to ship to Citizen, but I have ordered the tool kit and the battery from Amazon, for 31.56. Thanks Video was very informative and entertaining.

[@larryfromwisconsin9970]

I have that identical watch. I need a new crystal.

[@ferdinandmarkcruz21]

Is it hard to get that kind of battery? It is not the same as a normal button battery is it?

[@garywillacey9979]

One thing you didn't make clear & that was aligning the copper/brass part of the battery correctly & where exactly it should be positioned, all you said was be careful at that part. Thanks anyway.

[@Steuerlexi]

Awesome Video. Thanks my friend

[@ravenred201]

gosh we have a skyhawk version of this and it's doing the same. But the back of ours doesn't have the notches so you can't get into the back side! grrrr..

[@watchfan6180]

Congratulations! How old was watch when battery/capacitor was replaced??

[@bernardolhgc]

I have the same watch. Nice to know when the battery starts failing it’s possible to fix it! Do you know by any chance how to realign the GMT hour hand? Mine is 12 minutes misaligned unfortunately...

[@TheMediatorOfChaos]

Great video, been wondering how difficult it would be

[@markwietstock1537]

Not difficult at all, once you identify/find/order the correct "Eco-drive" power cell for your particular watch.

[@rw480]

Hello, I have a Nighthawk and replaced the battery but it still not keeping time. What do you suggest? My watchmaker suggest replacing the mechanism.

[@cathdy3736]

great video, i have an as2031 ti, got it used, was probably kept in a dark drawer, got it to work by placing it near a window for a whole day, but how do i know its time to replace a battery? i noticed that i need to charge the watch using strong led light to maintain its accuracy, but it keeps time for the whole day when i charge uisng the strong led charger,

[@friedhelmschroter8124]

The key criteria should be the lenght the internal rechargeable battery can hold its charge once it is fully loaded, for example by being 5/10 hours in direct sunlight (or longer period in weaker light). Note: When charging in sunlight there should be sufficient wind cooling to avoid heat up (lithium rechargeable batteries = Citizen Eco Drive watches hate high temperatures). In many watches a fully charged battery should last for 1/2 a year (check your manual). If the watch runs on the solar cell being in direct sunlight, but does not work any more after a few days (in bad/extreme cases after a few hours/minutes) according your need when it is moved to a dark environment it is time to replace the battery (movement in 2 second steps is the indicator for the charge being close to 0%). I would say replacement should earliest be necessary after 10 years. Only in case you mistreat your battery for example by shorting during installation, or by ESD touching it with your bare hands, or by deep discharge because of long time storage in a dark environment, or by putting it at quite high temperature the internal rechargeable battery must be replaced earlier. This video is very good on the exchange procedure (wear gloves to avoid ESD and skin particles on the battery that may cause some leakage current), do not touch especially the new battery with metal to avoid shortening), but it lacks a little on the test procedure to confirm that it is really necessary to exchange the battery. A watch running in 2 second steps is only a sign of low charge/voltage on the battery. If such 2 second steps occur one should immediately (the watch will stop 2 second steps after a few days) check if such low charge is caused by a) failure of the charging circuit/solar cell, b) not sufficient powerful light falling onto the watch. Both checks can be done by bringing the watch into direct sunlight (alternatively a strong LED, but not a incandescent light that heats the watch up strongly). Another point is, a replacement battery is charged only partially (ex factory typically around 30%). This means after battery exchange you should put the watch in strong light for a full initial charge (5/10 hours).

[@Cgt1984]

When replacing the battery, does it goes in a certain way?

[@PlayPauseChannel]

+christian garcia it might go in some funny ways. You need to make sure where a tiny pin thing on the battery goes in.

[@szeshunchung]

a nighthawk requires solar power, its literally fun j/k thanks for the easy guide of the video

[@michaelmaleke1591]

tengkiuuu

[@costastsatalios6541]

My friend good job but now the citizent is not the same waterproof ... this one is 200m in depth after the need for the ventilation machine as the factory does if you do not get out of the air the citizen is watertight but not as long as the manufacturer is probably now going only up to 50 meters deep

[@loxxrider]

You wouldn't happen to want to sell it would you? I've been looking for one of these.

[@PlayPauseChannel]

+loxxrider I'm afraid I can't... But thanks for watching.

[@kongpang1160]

If u r still looking to buy one on this day they r available again on many online website, yes it has been out of the market for a few years but now they r back, I have just ordered one for my daughter as she always borrowing mine....😄

[@kongpang1160]

I got hers from Jomashop with a 20% discount promo code , around US$179.00.

[@metatechnologist]

So the I came here after seeing a nighthawk with "do not open back, repair center service only"

[@GT5005]

How long did you have the watch before you had to replace the battery?

[@PlayPauseChannel]

I can't really remember, but 4 years at least i think.

[@lennonpolo]

Didn't you watch the video?

[@MrFahrenheit85]

wow

[@coldwarrior23]

My 14 year old eco drive just stopped so I brought it to the jeweller who told me that it's solar and there is no battery. He would not look into it and sent it to the Citizen repair center in...wherever! I tried to splain him that there is indeed a tiny battery for the solar cell to temporarily store energy, but alas he thinks I'm crazy!

[@adrianotero7963]

Andy Kenny find another place to take your watch..

[@musikdoktor]

Have to change my battery after 13 years..

[@danr1920]

I just got a new Citizen Ecodrive. The is smooth all around. It appears it's a no longer a do it yourself operation. The rotten @#$@#$^^%&'s!

[@edloki3057]

what model is it? I got 2 citizens (military field watch and diver watch) just a month ago and I can remove the case back on both of them.

[@markwietstock1537]

Every watch back can be removed. If the back is "smooth all around" that simply indicates it doesn't open by turning, but by using a jeweler's screwdriver to pop the back off. Use a magnifying glass to examine the entire perimeter of the back. You should be able to find a small notch somewhere in that perimeter for use of a screwdriver to remove the back.

[@mominulhaquerubel]

someone gift me Eco-drive. i used it in few days then keep it is drawers for more then 3 years. now it is working but second indicator jumps by two sec. Is it a problem? what should i do?

[@adamnoble587]

2 sec tick is telling you that the battery is failing. Buy a replacement ASAP. Fit it yourself as per the video

[@n2quads772]

I believe your watch just needs to charge by leaving it facing the sun for 4 or 5 hours and it should be like new.

[@adrianotero7963]

I did the same to a stiletto I had,and it would not revive no matter how much sun it got.... was without power too long,had to have the battery replaced...

[@markwietstock1537]

For anyone else looking at this comment, the "two-second jump" indicates the power cell needs charging. The power cell is just like any other lith ion battery ... they're designed to be continuously used, discharged and recharged, and work best/longest under these conditions. If it just sits in a drawer for years, the active material inside the battery may lose its charge/discharge capacity and become useless. Thus, if, after being put in direct sunlight for a day or so, the watch still doesn't resume normal operation, the power cell was probably damaged through non-use, and needs to be replaced.

[@leroybrowne6581]

Instead of all the focus on fanfare and music, would have been more educational if you actually showed where the contacts meet inside the watch. When I look inside my watch, there are two different spots that look like contact points. I have no idea if the battery is fitting correctly. Watching this video was useless.

[@marvingreen6644]

i was thinking the same thing

[@adrianotero7963]

This is very simple.....you don't need to be a rocket scientist to figure it out.....it goes in the same way it came out.....does that make sense?

[@NzStudio00]

No one sells a battery for this kind of watch except the regular battery.

[@markwietstock1537]

"No one" makes the "Eco-drive" power system but Citizen, either. The "regular" watch batteries you can buy retail are typically silver oxide. The power cell used in Citizen Eco-drive is probably lithium ion, and the designs/power cells for the various watches that use it are proprietary to Citizen. That means: 1) you can't get "their" Eco-drive batteries from any typical retail source, and 2) if you're going to do this repair you need to identify/find/order the correct Citizen power cell for your particular watch, as the video shows, e.g., the replacement is in an OEM, Citizen package.

[@friedhelmschroter8124]

Today Citizen claims "Never Needs a Battery". In my understanding this means Citizen expects that today the rechargeable battery inserted during production will show a life time of up to 40 years, while for old Eco Drive watches produced starting 1996 many people reported/confirmed a life time of 10 to 20 years. Seeing the large effort done on lithium batteries for automotive application life time may have really improved strongly in the last 20 years, but if today produced ML920 will really work up to 40 years can only be proven in 40 years (today this expectation is based on real field data for old production and comparing accelerated test data on old and new production). There are a few shops at EBay and at Amazon like www.ebay.com/itm/CITIZEN-SEIKO-WATCH-BATTERY-CAPACITOR-REPLACEMENT-PARTS-REPAIR-SERVICE/162137963338?hash=item25c02cfb4a:g:LYUAAOSwaB5XiaAy that are selling these specific rechargeable batteries for old Eco Drives. These batteries are specific because they consist out of a special 1.5V lithium cell + a metal contact welded to the battery's negative side (see golden part at 1:17). The special lithium cell is produced by Panasonic and is sizewise mostly a MT920 = diameter 9.5mm and height 2.0mm (for smaller watches a MT621). Citizen designates their batteries 295-xx and there exist at least 20 different xx types because the golden minus contact metal has different forms. One difficulty is: Citizen's manuals do not include/tell the correct 295-xx number for a specific watch/movement (Google/the internet may help to find this information).
