How to service a quartz movement. ETA 955 412. Watch repair tutorials 

Anyone who tries to repair a watch needs to have a good patience & memory to disassemble & assemble the watch mechanism back. Minute attention to detail is amazing. Truly a piece of art

I did not realize just how much disassembly went into a quartz movement nice work well videoed thankyou.

Surprisingly lots of work even for a quartz . Great work !

Thought you should know. I've watched this video and part 2 over and over. I just did the same job on a 955.121 with the day/date function. Doubt I'd ever accomplished completion without this video. Thanks!!

I’m a vehicle mechanic,(or was) people used to say how do you remember where all the parts go.Particularly on Auto boxes. Well some of us are born mechanics.It is all I ever wanted to do.I’m talking about when we repaired things. Not replace them. But! this is a different level. I can honestly say! How on earth do you remember how to reassemble a watch? I could certainly strip one,but that is where it would end, a pile of parts. 😁😁. Watchmakers! Born, not taught. Brilliant vids.

Great series of videos Mark. Hope there is lots more!

I have never seen the complete strip down of a quartz watch. I service my own quartz watch by replacing the batteries and if needed, the seals, but I never ever had to break it down into little pieces- this is quite fascinating to watch and learn, not as many parts as a mechanical, but there are parts for sure.

Hi Ferdinand. It helps to use non-magnetic tweezers, I recommend a decent pair of brass tweezers (Dumont are excellent). Use insulated tweezers when picking up the battery. I have an L&R cleaning machine (automatic with ultrasonic) and an Elma SuperElite cleaning machine (manual, no ultrasonic). I prefer the cheaper SuperElite as I have more control and it's less messy. I use cleaning fluid in the first jar and rinse in the second and third jars. Both cleaning and rinse fluids are made by L&R

see my answer to Ferdinand further down regarding the cleaning process. I will make a video in due course :)

It's unbelievable lots of respect for the technician

Thx for making this video Mark. I followed the instructions here to replace the PC board of my Hamilton Khaki which was damaged due to battery leakage and it's ticking fine now 🙂

Oh ! Good to see the most technical hands job from repair a watch ! Good for any who wants diy peoples ! Thanks ~ pal !

Nice video, but I'll like to see all the process. Thank you and Best wishes from Málaga!

I think your work is top grades and you show what others have lost very good watch repairs keep the good work up lets have many more vids thanks Brian

Great video, thanks. I just replaced a rusty movement in a hi-end wristwatch that has an ETA 956.112 movement in it. For the experience I disassembled the rusty one, figuring that I'd never get it back together. Well, now I can probably put in in my cleaning machine and have a shot at getting it back together, perhaps even working again. That would not be remotely possible without this video. You're providing great information, and presenting it extremely well. Thanks again. Cheers.

Great video excellent work what would it take for you to do a full strip down of a seiko 7548 quartz movement and reassemble,I've taken this up as a hobby over the last couple years concentrating on 7548 quartz movements.at the moment i have around 30 7548- 7000 and different models in this series,I'm learning as i go with some success and some failures,watching your work just inspires me to keep watching and learning love this hobby great satisfaction when you have success Cheers

You are a KING...biggest thanks..

Awesome,,,, to start servicing with quartz will be easier for a start for me. Thanks.....

Hi Mark, this video was instrumental in helping me service/repair my friend’s 955.432. Without this video I would not have had the confidence to tackle quartz. Thank you very much for all your videos and lessons!

Great work ! Thank you for this video , from Spain .

You are very smart by using a pair of brass tweezers. All quartz watches contain a magnet 🧲, which would cling onto regular tweezers. That is one ☝️ precision quartz watch movement you’re working on. All my watches contain a plastic movement. They keep time very well, but will only last a period of a few years. Your friend, Jeff.

Hi Mark, Many thanks for some interesting and informative videos. I've learned a lot from them. My limited experience is of wind-up mechanical movements and I'm familiar with tightening the cannon pinion when hands are slow to move after setting. I have a 1980s 13 jewel Cyma cal 131 that takes almost a minute for hands to move, then keeps perfect time. I haven't taken the dial off. How do you correct this problem. BrianB.

Thanks yet again on a very clean and clear tutorial. Like your videos a lot. I am wondering if you need to use different types of tweezers to work on Quartz and manual movements? Also, would be great if you actually show the cleaning process of the parts as well; the type of cleaning machine, type of cleaner / rinser, drying process, etc.

How could you remember all the sequences of assembly? Truly amazing.

i always have part one in life, i never manage to put it back again right! lol

Thank you!!! in Argentina almost no watchmaker will repair quartz...so they art terminated. Very few know how to repair mechanical either...Regards.

What an education! Never in a million years would I attempt that....well maybe the dismantling, but the re assembly....never.

Please can you tell me what can I use to clean the movement of my omega quartz watch because it's warks and stop sometimes... thanks for you very much... I'm following you from Iraq since many years

Tops! Thanks heaps

Thank you for your video.

I never would had thought I would see a plastic spacer ring in a watch that expensive. I have a mid-80s Hamilton with the 955.121 movement; it is an older variant of the movement shown in this video, with 7 jewels and a day-date window at 3:00.

spot on ,thanks

You must have excellent eyesight and a very steady hand.

Good job! I'm working on a variation of this same movement. (955.121) which has the day wheel, and I have yet to figure out how to remove it from the watch?

Hi, great educational video! Thanks for sharing! As I see it from here, this movement was in immaculate condition. Just curious, would it be really necessary to take a nice movement like this apart for cleaning? Another thing, lubrication of the quartz movements. I am going to search on your channel, as you've mentioned there is a video on that topic. Thank you!

Mark I really like your hand removal tool, it has a larger surface area to disperse weight over the dial. If you don't mind, what brand and model are they?

Thanks for watch ing

Very good jop thank you very much mark

Must admire the knowledge & patience to remove such minute parts & then put them back together. A watch repairer should have a good memory as well apart from all the precision tools required to service or maintain the watches

Great video excellent where can i get quartz movement thank you and parts for quartz watch and i am look for a meter to test quartz to check the movement if is isolating with out taking disassemble watch

8:18 a dot of chrome on the work surface says the chrome is becoming de-laminated. stunning ! but what's more stunning is what company makes all these little tiny parts and gears? amazing...

very nice

شكرا عمل ممتاز ومتقن شكراَ مره أخرى

Hi, i have watched a few of your videos and im going to tray and replace my first watch movement. I have recently got into repairing watch (just fashion watches atm as im still very much learning) do you know of any good sites to buy spares fpr watches, such as hugo boss, the Armani range of watches, lacoste, fossil, gucci, versace please. Thanks chris. Ps would it be easier to private messge, if so let me know how. Thanks again

Hi there, I have a £200 HUGO BOSS quartz watch. I changed the battery today as the watch had slowed down. Battery was replaced maybe a year or so ago. Even with new battery out in this morning, I noticed this evening it was 10 minutes behind the actual time... seems fine again now I've readjusted. But does it sound like my watch needs a service? It's either or approaching 3 years old and I haven't serviced it yet, only replaced a battery once since this time now, which shocked me really as I thought batteries should keep a watch running accurately for at least 2 years. Also how much would I be looking at for servicing this type of watch? Thanks, Peter

Any difference between cheap and expensive japanese quartz movements? Tou cqn put movement for 10 usd and ir works fine

Been trying to remove the damn stem for 3hrs....Merci :)

first time seeing the quality quartz watch movement… I thank you for that… I just bought a Timex expedition scout your obviously an expert and I already know it's not the quality of what I see in the video. May I please ask an expert a question? What do you think a Timex life expectancy of the movement is approximate? If you can answer may I say I would be grateful. So interesting learning about watches. I have mechanical antiques but now I'm just learning how quartz works and its unique very interesting. Anyway I hope I hear from you and thank you

Brilliant video - How on earth would you put that back together!...

This happened to me when I used it in an encabulator.

Very good 👍👏👏👏👏👏👏

...was out of characters... I will cover the cleaning machines in a future video.

Amazing

do you have any videos on how to modify a quartz watch? I was planning to change my watch looks

Great videos !! where can I buy an eta 255.112 I would like to fix an badly damaged tag heuer 2000

Help! I have a collection of watches some I dont use very often The other day I decided to replace all the batteries on the watches that had stopped. All the watches worked except 2 Rotary watches both with second hands is this a coincidence of a common fault Are the hands just seized and in need of oil or are they no good anymore. Thanks Tony

Hi Mark, Can a quartz movement electronics be damaged if you short out the battery, ie maybe with a tweezer, you short positive and negative?

I have an Omega with a Cal 1444 movement and it has an erratic seconds hand, it lines up with the dial markers from the 6 to the 11 position but jumps and goes out of line between 11 and 6, does this sound like one of the cogs is worn inside the movemement ? By the way it keeps good time..

I have a Victorinox chrono classic xls. I have 60 pages of specs and drawings on the 251.272 movement but have never actually seen it. It would be great to see a vid if you run across one!

Does it make any sense in servicing quartz movement?😁 What is the logic behind it,can understand about mechanical and automatic watches..

Hi there! Firstly , I am not a watch expert. I got a new watch as a gift and it had not battery on it, the battery was in the box and I tried putting it on my own. I somehow opened the wTch but, when I put in the battery , there was this small thing near the battery hole, I think it is called a spring or a contact, I'm not sure. In this video at 5.22 you remove the whole thing by holding on to an arm like thing (it has 9.5 written on it) The one that touches the battery terminals. That part broke and I don't know what to do. This part is really small and is there was way to fix it back to the watch? Thank you!

greetings sir, it seems to be my quartz watch chrono second dial wobbly and doesnt really stop at 12 plus sometimes it detach n i have to open the case to reattach. how to fix this?.. thank u..

What holds the hands on the shafts? Are the shafts slightly tapering?

Can the body now go through the ultrasonic cleaner or does the stator require removing first? Many thanks

My Quartz Tissot PR50 changes date at 01.35am, even with a new battery. Is it also fixable then? Thanks 🤟

Do you have a video for the service of a 715 movement

DEAR MARK WOULD HAVE LIKE TO SEE THE CLEANING PROCESS TOO.WHAT YOU USE TO CLEAN THE PARTS

I have an Oakley holeshot which means a whole lot to me but the crown snapped off the rod, is this something that can be repaired? I know very little about watches.

I have an old seiko quartz. Can't find the release point for the stem. If I sent you a photo would you be able to spot it? Thanks.

I've noticed on some 955.412 movements that the crown stem removal button shows a full arrow pointing to it but on others the arrow is interrupted ?? Is there a reason for this ??

Super!

Hi, a own a HEUER 230006 and the coil is damaged. I figured out the movement is ETA 555.112. As I saw in the video, if the circuit board is damaged it has to be replaced. Therefore I've looking for the replacement but there's no replacement under the same reference number, instead there are circuit boards ETA 955.112. This last one would work for my watch? Thanks for your time

Hi, I am replacing a 955.412 movement in a military watch with no date. the only movement i can find have date ring, is it ok to remove date ring and leave it of.

Hello. I have a men's Geneve 14K gold watch with a ETA 955414 movement. I wanted to replace the battery and ran into a problem. I pulled on the stem to remove it and the crown separated from the stem. The crown has a female end while the stem has a male end. Very similar to the way a grafting tool creates a male and female end. Do I replaced the battery and the watch runs fine. The problem I have is that I can't reattach the crown. When I push the crown onto the stem, the stem recesses into the movement too far and I am unable to engage the crown onto the stem. Do you have any idea how I can fix this problem. Thanks

hi! can you make a video on how to fix the date on a zodiac seadragon. The date on the watch is not working, it is stuck on # 3. Thank's

+Watch Repair Channel "I Found it" All is good.

Thinking about the magnetic tweezers probably when you grabbed the battery at +&- sides at once🤷

+Watch Repair Channel Please tell me how do you remove the winding stem from an ETA 955.414 movement? So the movement can be replaced. Your advice would much appreciated.

nice

Hi, what is the size if the screw for the movement ring?

Versace quartz it seem I cannot remove movement due to inner ring? Can you help with this, Regards

My grandpa gave me his 30 year old quartz watch and it still keeps better time than my automatic seiko 5

Was the lubrication for the this watch ?

exelente

Where can I buy the tab that's located under the battery? I am not sure what it is called but in the video it is a gold color tab that touches the bottom of the battery.

I have made a picture walkthrough of this video (www.watchrepairtalk.com/topic/13730-eta-calibre-955112-service-walkthrough/) which basically mimic and complements the video as it includes lubrication suggestions according to ETA’s technical communication which was intentionally omitted in the videos to save time. Hope you'll find the walkthrough useful!

thank you man,if in apocalypse you find your self near brooklyn area without ammunition and clean water , I'll hook you up!

Is the ETA 255.462 very different?

That is how a quartz movement should be made!

Good

how to you remove just stem from this movement?

I want to change the movement How I can take the s and crown out

My ETA 955 412 now skips 5 seconds, even with new battery. Any clue??

It seems to me that you need a great memory to remember where all the tiny parts go 😊😊

Hi weres part 2

Is this done with the naked eye?

ini mesinnya terbuat dari emaskah?

Wow!! Would not like to be putting that back together. 🍀🍀🤪

My citizen quartz needs a service

Pleas sound high volium
