You're a godsent! I bought the exact same kind of clock mechanism to make it into a gift for someone but my curiosity got the better of me and I opened the back, and the gears went flying everywhere! Thanks for your help I was able to put it back together and get it working :)

My dad bought a nice wooden German wall clock with pandolium for the living room. After a few years, my mom got attached to it. But a loose screw caused the clock to fall on the floor. When I was visiting them, my mom complain that my dad didn't hammer the nail hard enough to the wall. Poor clock fell and all the gears went up to the kitchen. While cleaning the fridge, she found a few gears under the fridge. I went to a clock shop and asked for the cheapest clock with pandolium. The clerk was kind enough to tell me the difference between contious movement and the jaggy one. Contious movement uses a full electric motor and uses much more power. However, it is very quiet. To make the story short, I fixed the clock and put it up to the wall just before mother's day. She said that was the best mother's day gift she received! The movement was made in Japan. It's been twenty years and still working.

I always wondered how these clocks mechanisms works, very interesting!

First one of these I saw close up was in 1971 and it was already a few years old. It had no seconds hand, and it ran off an alkaline C cell that would last for a little more than a year. I wish I had it for comparison: possibly no integrated circuits, probably a CMOS counter to get the 8 Hz or 1Hz or whatever frequency from 32768. CMOS 4000-series chips showed up in 1968, so maybe... I have a quartz controlled alarm clock with a backup battery. In eight years it’s gained 20 minutes because the crystal vibrates just a little too fast. So the clock gains about 0.4 seconds a day.

One of the most original electronics channel on youtube.

you use analog test gear very nicely your circuit analysis is amazing i love your videos very informative

I never thought our clock would run again. It does! You are a genius!!!

Excellent, thank you for putting this up. Had an issue putting the coil back together and was able to see from the way you had it assembled how it should go together, even though a slightly different design. 10/10

Thank you! I've repaired my quartz clock thanks to your video.

You've created a time machine at the end. 😀

this helped me put together a clock i made some years ago, the mechanism was rubbish, the battery had gone rusty. i decided the pull it apart, all the parts got mixed up. 0v built up crud on board connection. part axle slight bend. i fixed the minor problems. now works ok

Thank you very much for your demonstration and explanation! For example:- I have an old clock that did not function properly but it's frame, dial and hands are beautiful and so I am not willing to throw it out. In such a case I can buy a new quartz clock moment and replace the old moment of the clock by new moment so that the old clock will function as a new clock. I got such an Idea by watching the video. So that we can avoid throwing old dead clocks into garbage or by the side of road or street.

thank you sir you saved my bacon when a job i was working on due to deliver in an hr went wrong when the casing was opened and exploded all over my workbench!! cogs everywhere!! after finding your video its now working perfect again! THANKS!!

Thank you! Awesome to see the inside of the clock!

I disassembled two of such mechanisms and managed to re-assemble both. The other one i managed to re-assemble was a radio-controlled mechanism, it took at least 8 takes to re-install all wheels in correct positions... But it still works well.

The turbo clock at the end was great!

Had one that, after around a decade of running, failed a funny way. The clock would move the second hand tick by tick as usual, but then at random points along the sweep the second hand would jump ahead 20-30 seconds per tick, probably because the little gearbox inside had worn out the pivots it ran on. Did a transplant of the clock mechanism from another cheap and nasty clock, and it lives again, keeping good time. As to the "continuous movement" style, I am not a fan, because of the very short battery life. They typically last under 2 months per battery, while the single tick versions will go for around 2 years on a single alkaline cell. Took one that was otherwise a nice clock, but which ate a battery per month, and converted it to run off 12V DC from a solar panel, using a simple voltage regulator of a series resistor of around 4k7, a red LED as voltage regulator and a 1000uF capacitor to provide the current pulses for operation. then added some used SMD white LED's insode as illumination for the dial, and even with less than 0.5mA of current through them ( running through the series resistor so as to keep overall current the same with just the LED dropping a little of the voltage) they are way too bright, had to add a resistor of 5k6 across the LED's to dim them more, but still there is enough light from them to cast a shadow and light up the room with a night light after dark. Was a good recycle of an otherwise not usable clock.

1.5 mA power consumption, no wonder why my wall clock drains it's battery so quick, it has probably the same crappy motor! By the way thanks for great video 👍

Well to be fair the listing clearly states "hands repair"... So I think it was pretty transparent that the hands were in less than perfect condition!

My favourite video so far!

Thank you, this allowed me to fix the gears in my clock!

Thanks for posting this! I needed to put mine back together, your video really helped.

15:33 nice beat 👍.

The weak part of all those movements is the springy battery contacts, a little humidity is enough to corrode the pads on the PCB over the years. I have an old non-quartz version which has a balance wheel movement powered by a couple of coils and a single transistor board, once it starts moving it can run off a calculator solar panel, it's also adjustable.

are u speaking or singing :D

I’m always so fascinated by your quartz clock ⏰ motor videos. Once I find an old, or broken 😞 clock 🕰️ motor, I take it apart for the little magnet 🧲. I also find the copper copy coil fascinating 🧐. It is this copper 👮‍♀️ coil, which gives the magnetic 🧲 gear ⚙️ the impulse, each, EXACTLY one ☝️ second apart, enabling SUPERIOR time keeping ability, although, I do not know how this works. Sorry 😞 about all the emoji’s, and the long comment, but these videos are very interesting 🧐. Your friend, Jeff.

Nice video. Saw the inside of the continues running second hand for the first time. Have explored the 'step type second hand' clock earlier. Also be sure to pat the 🐈 when she appears on camera. She is nice and fluffy.

Wow :) You bent space-time Continuum :D greetings from Poland :)

The only and best video on this subject on the internet, liked 👅

my clocks hour hand is loose . it rotates easily what to do?

Great help. I opened one to see if I could rob the longer spindle. That was a fail. But I am always inquisitive to see if I can fix things. Thanks to your demo, accompanied by your quaint narrative, I got it together and working again. Same day, I tried to reverse the swing of fridge doors, but no video showed how to dismantle the trim on the tops and bottoms glued to the door, where hand grips are. They would have to come off, because the doors have to be inverted, and then the hand grips are in the wrong place. I figured it can't be done, but I'd still like to dismantle so as to re-spray the doors so that there is no evidence of masking tape, overspread or gaps. Now I'm awaiting delivery of new door gaskets, which another installation video demonstrated.:)

Constant running clocks are silent, so they may be good if you have trouble sleeping because of clock ticking

02:36 Interesting about the counter-weight on the second hand... it gives the second hand a little gravity-boost when the pointer is going up on the left side of the clock's dial and a gravity-brake when the pointer is on the right side of the clock's dial.

upvote for vaccuum display. You are awesome. Love how you talk too.

Just last week I resurrected one of those after being outside in the soil for five years.

I found this mega helpful and very informative, thanks for doing this video :)

Time flies when you're having fun....

LMAO at the accent and the cat, I mean it in a nice way.

Great analyses. Very high battery usage for the continuous running motor (1.5 mA) The stepper motor clocks usually run for well over 1 year on the same battery.

This is exactly like mine. Should be a cinch to reassemble. I was guessing and WAY off track! Thank you Mr. Callabash wherever you are. Anyone under 50 will have no clue as to what that means. POOR YOU!!! Db

Good video that show it can do super-fast moving!

Here’s my cat coming to help me... Doesn’t help

I tested a quartz movement (with smooth sweeping second hand) that I bought online for $9 shipped. It draws 0.17 mA.

Easy to hear you love clocks. 😉👍

A decent sweep movement like the Young Town 12888 or SKP sweep is using less than 0.15 mA.

Some quartz movements have 3 gears between the rotor and the second hand wheel.

I have a cheap Chinese mechanism but it's old, sold like this it was £2.70 (probably £1.50 if bought direct) from a UK shop back in 1996. It looks very similar but it's not see through, same text. Same mounting but better plastic hands and has a buildt in Hook for wall mounting. One rechargeable AA lasts 3 years. Same constant movement style.

What’s wrong when spindle motor not working. ( I have checked motor coil - it’s ok ). Magnet is not rotating. Any help? Thanks in advance.

Thank you for your effort.

The second hand of the clock is completely ruined, RIP 😔

1:12 I love your antique Mauthe. i have a triple chime colonial of zeeland grandfather clock. i would love to here the chimes (assuming its westminster chime) of your antique clock.

Just out of curiosity, do you collect those mechanical clocks? Or do you have just that one?

I just watched 20 minutes of video about a man learning how a tiny clock part works. Tiny but a little bit complicated.

You just invented a time machine at the end of your video,right ! A few years ago I bought a battery operated Seiko wall clock that had a quiet mechanism like that one,the clock was $60.00. I shutter to think it might have had a .79 cent movement in it. It was for my mom ,but I know the battery lasted for more than 1 year in the clock I gave her.

Great sir you have nicely explained 💖

Muito bem explicado. Parabéns

Thanks, my clock is not running and keeping excellent time just from the help of the first 13 min. of your video.

To measure the power needed to run the movement you should use a 1.5VDC regulated power supply, measure the current consumption and then calculate power. To find out how long the battery will run you need to determine the minimum operating voltage, measure current and then calculate power again. Power consumption will most likely change with battery terminal voltage. Knowing this you can consult the battery manufacturers specifications on the battery capacity as related to discharge rate. Capacity is rated at a constant current draw and then plotted. As the battery current increases the capacity will be reduced.

Thank you, I just fixed my cheap decorative clock. The minute only and one with seconds are different with ~ 3 - 4 more gears.

Great your teaching videos and your funny Czenglish irony. TOP KZfaqr!!

The continuous movement is hence not so popular, as it consumes more battery. If this clock is 8Hz motor frequency, the step movement will have a frequency of 1Hz. Also, the power consumption is equally less and hence step motor lasts for years.

A small tip: You should first put cell from the positive terminal and then you can slide the negative terminal! (Only for clocks).

Czenglish hype

Very interesting....will the clock still work if I disarmed the second hand to try and stop the clock ticking...as I have mine in my bedroom.

I learned so much about quartz movement. Thanks. BTW, can I just change the solenoid instead of replacing the whole unit because the stem size for my old Bulova is no where to be found. It is only 7mm long. Besides, i can reuse the original hands.

The clock become crazy

This calc is amazing!

Complete knowledge. Thanks for....

Is it possible to convert it to a ticking second hand...to reduce batt consumption?

These cheap "sweep" movements are a real pain. As you say the battery life is terrible on them, and the worst part of it is they've completely taken over the cheap end of the market. It seems to be virtually impossible to get hold of the old-style mechanisms which moved once per second. They are also unreliable -- they start to malfunction as soon as the battery becomes weak, and eventually stop working at all.

Current consumption should be approx 200 microamps / 0.2ma for a 5168S or 6168S movement. Check the current consumption with just the stepper motor installed to start with. I suspect binding in the gear train. A small drop of light watch oil in the bottom of each of the pivot holes will reduce friction, wear and noise. FYI, the SEIKO variant of this type of 'sweep seconds' movement from the 1980's suffered terribly from excessive wear to the motor bearing cups and second hand wheel rear pivot, causing the plastic to turn to white powder.

Please upload a video which shows demonstrating and explaining about quartz clock moment with quarter chiming system.

wow, you make intersting also the simpliest thing, my compliments

Nice information sir salute

Hello, is it also possible to slow down quartz machine? Specifically to make the one day on clock last 365 days (1 year), so slow down about 365 times. Thank you!

My dad used to make/repair clocks think he bought similar mechanisms. The ones he had you could see a tiny transistor next to the coil. Some of them are still working after 15 years or more

The plastic clocks seem quite reliable too, i have not seen many fail.:-) I did think 32.768khz for the crystal, it used to be typical for cheap watches a long time ago. I would imagine that every plastic clock module has the same style of gearbox, china would have made it as simple as possible for cost of manufacture. Real clocks are loverly, but unless it's a real good quality one, it's not worth repairing it. Sad yes :-(

Hi sir,Love from India. I have a doubt,if i intent to change the rotating direction of clock(meaning it will move anticlockwise) what changes should I make?

I've used these types of movements and the batteries I find last give or take a year before they stop.

Can I turn it into a turbo clock using 555 oscillator?? Why ask that question?? Of course, you can turn anything into anything. Very nice video.

19:18 Instead of that, I just changed the crystal in the clock, so now "one minute" is just "26 seconds"! He-he... 😊

8:09 I noticed a cat paw. What a distraction

hello very good video I would like to know if I put a duracell battery can it last longer?

19:42 How you done that?? Directly connected to coil or connected to the place of the crystal??

Gracias por el video. Saludos desde Lima Perú.

FYI besides the "Chinese rubbish" you mentioned @ 1:24, China also made one of the most accurate clock for their Tiangong space station, so accurate it won't have to be reset for another 30 million years. Search "China's Atomic clock: The Most Accurate Clock in the World".

Hi, will you make a teardown of some old polish poduct? You're near Poland so I thing you have some device from this country :)

Very interesting video

Love the cat!

So how long does the battery last for that kind of mechanism??

Nice super speed clock xD

Is quartz crystal unit 32.768KHZ for every Quartz Clock ? How can I find out crystal for my clock?

I had a nice ladybug cooking timer, I took it apart to see the insides and couldn't put it back. Over the years I lost a few of the small parts. Now whenever I see the ladybug shell I feel a pang of guilt :(

Very Nice

*What is deffrient between the 1 second bit quartz and sweep movement quartz ,I mean it has the same mechanism then why this one sweeping and the another one stop bit 1 second?it's for the coil*??

I was given a caculator just like that in math class and told I wouldnt amount to much because I couldnt do math without one, now EVERYONE uses a caculator. Guess I wasnt so dumb after all.

I love his accent!!! Also, I'm currently trying to reassemble a quarts mechanism with a sweep second hand, extra gears! Db And, of course, like cats everywhere it wants to be the center of attention! That seems to be universal. I'm glad I don't own a lion!!! Does yours sit on your face?!!! Db And why do they settle and put their butts in your face? And why don't their butts smell bad?! Cat enigmas1 Db

Clock Gone Wild 😁👍

Excellent work truly amazing ... can u share me the circuit to speed up the clock speed

Another geeeeeaaaar :)
