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
True. These days one can use own phone to take a lot of pictures during disassembly, or go online for a picture or diagram, but no technology will help one develop patience and motor skills to work with tiny parts.
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.
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 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.
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.
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.
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
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 🙂
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!
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
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!
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
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, 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.
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
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
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.
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?
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.
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...
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
Not all quartz movement are created equal. There are tons of disposable quartz but there are also higher end quartz and even luxury tier quartz watches, both are serviceable and makes a lot of sense.. some are even designed to be more easily serviceable.
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 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!
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.
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
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.
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
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..
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, 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
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 ??
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!
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.
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..
I would like to service my late dad's quartz watch. It has stopped ticking a long time ago. If I take it apart I fear I will never be able to remember where all the parts go and in what order. Filming the disassembly would be a solution, but my camera does not make sharp macro images.
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!
+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.
There's possibly a latch (button) you can press to disengage the stem. It may not be apparent with the naked eye but you'll see it with a loupe if that'ts the release mechanism. .
Part 2 of my video would be full of beeps covering up my swearing as I tried to put it back together. There would probably be some crying as well. Joking aside....how dirty can a closed watch really get? Seems like it would still be in mint shape even after many years.

Thank you!!! in Argentina almost no watchmaker will repair quartz...so they art terminated. Very few know how to repair mechanical either...Regards.
No problem, much easier to replace all the movement, and they are affordable! Is insane so much work on a quartz movement.
