- These days almost all analogue clocks, clocks with hands and faces, have quartz controlled, battery powered movements. These always seem to fail after a bit so lets have a look inside a faulty one to see how it works. Maybe we can even fix it.
This is where I got my replacement clock mechanism from. He has a good range of better quality movements. DANS CLOCK SHOP www.ebay.co.uk...
Thank you very much! This video is really helpful. People can repair their own clocks at home. As well as it helps to avoid throwing old damaged clocks into garbage or side of road or street. Repairing and restoring old clocks helps to keep the environment clean and healthy as well as avoid wastage of old ones.
Yes. So tempting just to throw throw them away because they are so cheap when, probably, most can be repaired in a few minutes.
@@TripplikitElectronics Please upload a video that shows connecting and installing electronic chime that hourly play melody and count the hours to the quartz clock moment.
@@TripplikitElectronics People are still not aware that the old damaged quartz clock moments can be repaired so that they are tempted to throw it out. When people become aware that quartz clock moments can be repaired they try to repair and restore dead quartz clocks. This video will make people alert about it so such temptation is avoided.
Thanks for this mate. 👍 👍👍
Although Alibaba (and their '8 weeks if you're lucky' shipping) has lots of these mechanisms, you need to be precise as to dimensions and diameters, and the particular one I need is unavailable, so I pulled my mechanism apart to find that one of the battery-to-PCB contacts had corroded. In doing the pull down, bits went everywhere, of course, so your video helped me get it all back together again after I addressed the corroded contact. 👍👍👍
Glad it was helpful. As you'll have noticed, I paid a bit extra for a good quality mechanism from a local supplier.
Good video mine done that and after finding this video is happily working again clear instructions . Mine did not have the copper bit in the end but plastic
Glad you found the video helpful.
@TripplikitElectronics Plastic can be lubricated, but it requires a very careful choice of lubricant. A conventional oil or grease will act as a solvent against the plastic. Silicone and PFPE oils are generally safe on all plastics.
Thanks for that. Very useful information.
Huge Thanks to you!! I've finally fixed my Nightmare Before Christmas wall clock!!!
Glad you found it useful. Sounds like another clock that's worth fixing for its personal value.
I have a small doubt . The Third gear from the drive gear which is on the top . why there are circular cut paths??
Didn't notice that - well spotted. Do you think I re-assembled it incorrectly?
I have 2 that are late and I have already disarmed it several times without a possible solution, as I saw in a video, increasing the voltage intensity is corrected, and this is achieved by placing an extra battery in parallel that would add intensity while maintaining the same voltage.
These clock modules should draw very little current. It seems strange that yours needs two batteries to work properly.
@@TripplikitElectronicsI think the pulses are rather high current created by discharging a capacitor through the stator coil. A degraded capacitor could prevent sufficiently strong pulses from reaching the stator.
Good repair
Thank you.
Thank you ❤
Glad you found it useful.
Good video i to use my fingers and the tweezers sitting on the bench
Good tip. Glad you liked the video.
Good job man.
it helped alot.
Glad to hear it!
You are putting to must oil. you are not using a tweezer .
Thank you for this video!! I have the exact same Mechanism in my clock,which had not been working for a while so I decided to take it apart and with your helpful video I managed to get it back together and it's now working, so thanks heaps😊
Glad it helped
I had one where the battery had a slight leak and it creaped up the metal strips to the pcb, made a mess of the copper pads.
But after a clean, the clock started ok :-D
I have also had ones that stop for no reason, the clock divider+coil driver must have been dead.
I've always just thrown them away up to making that at video. That one was just bad contacts and it's still going so, in future, I'll at least have a look inside. Congratulations on recovering one after a battery leak!
Por isso os relógio não duram muito tempo. pra que, não tem necessidade de usar pilha alcalina em um relógio de parede. as comuns tem uma ótima duração e evita vazamentos...
Thank you for this video! Fixing my clock really made my day ;-)
I'm so glad!

شكرا لك يا سيدي على هذا الفيديو المفيد لقد اصلحت ساعتي التي لم تكن تعمل منذ فتره 😉😉😉😉👑
أنا سعيد لأنك وجدتها مفيدة. شكرا لترجمة غوغل.
I am glad you found it useful. Thanks to Google translate.
I have been watching these clock repair videos for quite sometime .Nothing ever comes close to yours. I am so thankful to you for your great video. Please keep posting such useful videos.
Thank you very much - I'm glad you found it helpful. I do have some more repair videos in the pipeline.
Agree!👍🏼
Wow very helpful and clear vid! Had a sudden urge to fix my parents' wall clock that hasn't been working in years. Saw your video and with trial and error on the parts, I found that the problem was inefficient pressure on the power board! Got some tape in there and now it's perfect! Thanks for your guide on how to assemble it!
Glad you found the video helpful.
The driver IC divides the 32768Hz crystal down to create pulsed AC with alternating plus-minus pulses every second. The permanent magnet rotor has north on 180 degrees an south on the other 180 degrees. The four points on the electromagnet are 90 degrees apart and when energized will pull the rotor to be centered between the two like poles of the electromagnet. When the pulse ends, the electromagnet de-energizes and the rotor rebounds to its resting position off center of the point at which it was when energized. Gaps between the rotor and stator are slightly smaller at the two points anticlockwise from the energized position, causing the rotor to move predictably anticlockwise at the next pulse which has opposite polarity. In other words, this is an AC motor with predictable resting positions.
Thanks for your knowledgable explanation. I didn't look into how the actual "motor" works. Sounds interesting - perhaps I should do another video on the subject.
After following your lead, i managed to get my clock working again. Thank you. Clear, precise and informative. Top man
It is really nice to hear that people are finding my videos are helpful. Thanks for the comment.
How to assemble a quartz clock
I got one that seems to work fine for a few weeks/months and then suddenly begins losing time. When I check the battery voltage, it's at around 1.4V (new one read 1.6V). I've cleaned the PCB with IPA and even touched up the solder joints with my iron. The gears don't seem to be dirty or look damaged. It's difficult to troubleshoot since I have to wait potentially weeks or months to see if what I did made any difference. Not really sure what's up with it.
They are so much built down to a price it's probably poor assembly or a poor quality part wearing out early. Look like you've tried everything to repair it so you'll probably just have to replace it.
Cleaning those pressure electrical contact tabs should go a long way toward making the clock reliable. if you don't have contact cleaner...then rubbing alcohol and a paper towel will do it.. dry with the a paper towel because it is mildly abrasive which is good.
I agree. It is surprising how much those contacts getting dirty can affect the performance. Despite the current usage being minute.
I have lost the cog that you put in at 14:57 the transparent cog. Do you know where I can get this singular cog?
Sadly I think these clock mechanisms are so cheap that it is not worth anyone keeping spares for them. It is basically a throw away item. Sadly the same applies for considerably more expensive units - see the Gigaset DECT phone handset I attempted to repair in October 2020.
There are only 2 possible causes for the failure. Plastic expanding or Battery replacement method. Because the clock just sits on the wall there is no physical contact other than changing the battery. The rechargeable battery may have a larger diameter than non rechargeable which may push the contact off causing the loss of power.
The 2nd clock must have cheaper plastic that's wearing or expanding. The magnet gear is not seating in the socket so its slipping. The replacement hands could be binding causing the magnet gear to wear the points causing it to jump the teeth.
It may need a shim to hold it in place.
Thanks for the information. You sound a lot more knowledgable than me on these clock mechanisms. I shall certainly make use of your information on the next one I look at.
What typicaly kills them is the shaft piviots (bearings) wear loose to a point where the mechnism binds up and stops . I have seen people put a tiny drop of clock oil on these points and get them back running again, I have also seen the battery bars corrode make bad contact and stop them as well. but if the bearings are worn badly enougth oiling wont fix them . its important to note these mechnisums do come with the option of the threaded shaft that goes thorugh the clock face having a number of diffrent lengths , you can get them with the option of having a swinging fake pendulum, some tick off the seconds and that noise anoys some people , some run second hand smooth and dont tick as they operate ..
I always thought you shouldn't oil plastic bearings. Was I wrong? They are so cheap that once the bearings get worn it's probably best to just replace them.
There are so many options available for quartz clock mechanisms it is quite hard to choose the correct one for your application.
I must admit I've never had one with a fake tick or a fake pendulum!
I have got a problem with my clock, the second hands got ticking then it have stop ticking and the time are going really fast. Do you know why?
I have been advised to replace all of these gears which I don't think I would need to?
I have never heard of that problem before! It would probably be cheaper to replace the clock mechanism rather than buy new gears. I would actually be very surprised if you could find new gears to buy.
Na maioria das vezes o problema é só de mau contado na saída de alimentação das placas para as ferragens de suporte das pilhas. Pode-se acertar o contato, colocando novamente a pressão adequada ou soldando um fio na saída da placa para a ferragem, usando ferro de soldar com potência acima de 40W e um bom fluxo de solda. Saudações do Brasil 🇧🇷
Olá no Brasil e obrigado por suas idéias. Muito útil.
Clumsy piece of work.
Perfect! I didn't know how the electro-magnetic mechanism worked...only that there is the quartz crystal controlled oscillator. Now I can set about taking my old LL Bean ( seiko) moon phase mecanism apart. It "fibbulates) instead of doing a full tick...so maybe clean and lube will do it. Thumbs Up !
Hope that fixes your problem. You would have thought that a bad contact would just cause the clock to stop - however I've seen that effect too.
Thank you very very much, very helpful. Rescued me!!!
Glad you found it useful.
Clesrly explained! Thank you 👍
Glad it was helpful!
Useful ❤
Glad you found it helpful.
Thank you so much!
You're welcome!
I had a watch do that recently. Losing time, then stopping. New battery put in a month ago.
I seems a bad battery or bad connections are generally the cause of running slow in quartz time pieces.
MUITO interessante
Gracias.
Thank you so much. My mechanism came a part whike trying to clean the circuit board and connectors and I refused to purchaseanother cheap China made mechanism. Your video was very helpful in helping me reassemble and get it working properly. Cheers.
Glad you found it helpful.
Thanks a lot for all your efforts. I got mine apart and one of the wheels had some broken cogs. Hence why it was ticking and only worked for a little while. Thanks again and keep safe you and yours.
That's interesting. I know the cogs are only plastic but I wouldn't have thought the "motor" would have the power to damage them. Maybe someone used too much force trying to set the time.
@@TripplikitElectronics Possible! Thanks again and keep safe you and yours.
Wh9oa there pardner! Way, way too much oil!!! A tiny bit on each shaft is it. None on the gears. Just clean the gears with a clean lint free rag.
Thanks for that Mark. As you probably guessed I'm not an expert with clock mechanisms. I'm more used to pouring oil liberally on my bicycle to stop it rusting up. I'll remember in future - a tiny bit on the shaft.
Do you have a part number for the mechanism. The cog that connects to the magnetized one looks similar to the one that I have that's malformed.
Sorry, I don't remember seeing any part numbers on either of the clock mechanisms.
I have a Braun BC02BL clock. It doesn't work well. The minute hand doesn't move and remains ever in the same position. The seconds hand works well. What about my problem? Does someone know?
Sounds like the minute hand is stuck somehow or not pushed on to the shaft possible. If the seconds and hours are working it would imply the mechanism is OK.
I had one that always showed something to or something past 6 - yes the hour hand had come loose and dropped down to the bottom under gravity!
@@TripplikitElectronics thanks for your answer. Only the seconds hand works well. The minutes one works for a while (5-15 minutes) and then it stops in the same position. I'd like to open the clock, but I'm afraid to broke it. I'll ask a
watchmaker, hoping it is not an expensive problem :(
Quartz Chime. When I hear the little "click" at the top of the hour just prior to the chime going off, the chime does not sound. In your expert opinion, what is the problem?
Sorry, I have not taken one apart that has a chime. I'm not an expert in clocks - I just really took them apart out of curiosity. If it goes "click" it sounds like the chime mechanism is trying to work. Maybe the bell or whatever that makes the chime has become detached and the striker is no longer hitting it. Just a guess.
@@TripplikitElectronics thank you for taking the time to respond ~♡~
I have a quartz clock mechanism I'm trying to repair any tips on how to repair it?
Hi Jay, The fault on the one I took apart was that the battery holder was making poor contact onto the PCB. I just had to clean the contacts - easy fix.
Generally, if there is anything seriously wrong with them, it won't be worth fixing because replacements are so cheap.
I only really took them apart out of interest and to make a video.
Gracias por publicar! excelente video...! el problema de mi reloj de pared, es que el filamento de bronce de la bobina esta suelto. No lo he podido reparar.
Sorry for replaying in English. Again they are so cheap it probably easier to get a new one.
Hi
How can I Make
24 Hours And 45 Minutes Clocks Measurement
Let's Say For Other Planets
well Actually My Circadian Rhythm Is 24 Hours and about 48 Minutes on Average
I have Delayed Sleep Phase Disorder
Dspd Non-24 Hours
some People Call Me Martians
I Know It Is Frustrating To Wake Up 45 Minutes Later Every Day
But I accepted This As a 32-year-Old
i am interested To Make Clock That Tracks My Body clock
Do You Know Any Html Or JavaScript Or Any Other Codes To make
or Is there any Html Codes Of Martian Time
That I Can change It From 39 Minutes To 45-48 Minutes Longer?
If Not
How Can I Slow Down A Quartz Clock To Run little Slower
3% Percent Slower
Thank You So Much Sir
I hope You Have Some Solutions For Me
I built an alarm clock using an Arduino and I could easily set one "second" to be 1030mS. The electronics on a quartz clock puts out a pulse every 1s. Perhaps you could find something to put a pulse out accurately at a slightly longer duration. The clock electronics is timed by a quartz crystal. It might be possible to connect capacitors to the crystal to make it run a bit slow. Thanks - interesting problem.
@@TripplikitElectronics Thank You So Much 👍
Do You mean Ceramic Disk Capacitors Or electrolytic capacitor?
ceramics of a few pico farad - and doing this may well just kill the Xtal oscillator.
@@TripplikitElectronics i tried 33 and 47 pf ciramic capacitor
It stopped working
Then i tryed 5 and 7 pico farad i keeps working without slowing down
Should i connect it in Series?
Excellent video, really helped me assemble the clock back together!
Thanks. Glad the video helped you.
muchas gracias mi reloj era igual q el segundo que explicasteis, millón gracias
Me alegro de que haya sido útil.
Thanks I trids lot finally I got it☺️☺️☺️👍👍
Great - glad you found the video useful.
Great video!👍👍
Thanks. Glad you enjoyed it.
Thank you Sir
Most welcome
Love you👏🏼
Thank you. Glad to have helped.
Nice Thank You. It was very help full.
I guess it is kinda off topic but do anyone know a good website to watch newly released series online ?
@Kingsley Milan i would suggest flixzone. You can find it by googling =)
silly sod. all you do is buy a cheap clock from Poundland and swap the bits in your clock. don't need to get someone to do it. the heads just push on
Part of the point I make in the video is that I've found cheap clock mechanisms (and I'm sure that includes Poundland ones) to be really unreliable. That's why I bought a relatively expensive one - which is still keeping perfect time.
@@James_Bowie hehe yes hands although too long for hands, arms would be better. Perhaps the heads of a snake
"the heads just push on" ... Really? There we all were thinking that the _hands_ just push on. Silly sod.
