This is just the video I've been searching for! Nobody ever shows full disassembly of the quartz movement, this is perfect and it just came up randomly lol.
Thanks for posting! I had the same problem. The second hand stuttered in place so I disassembled to find the large white plastic wheel has two broken teeth. How does that happen? I checked my spares, but no luck on the part. Movement Y121A Japan is fairly common. I might find something at a flea market for a couple dollars, but putting on the train of wheels bridge with these little bits is a nightmare.
Thank you for the comment! And for the story. Y121E is hard to repair, I agree. It was made simple, but they built it to be inconvenient for disassembling/assembling. Hopefully you will find a replacement.
Thumbs up for your video ! 👍 I have a Festina F16374 with the same movement and the minute hand started to shake back and forth each time second hand is ticking. I would like to open it but I'm not sure how to do it. I noticed that you aligned all the hands before removing them. Do you have to also align the second hand when you reinstall it please ? I read somewhere that the hour and minute hand are linked but I don't know about the second hand on quartz movement. Also does the dial is glued on the movement ? 🙏
Thank you! The hands are better to be aligned before removing them to prevent their possible damage. When installing the second hand, it could be aligned to any position, just to match hand's tip with any of the second marks on the dial. For not so high quality dials, this is not necessary, because dials can have misalignment by their self. Yes, hour and minute hands are meshed together via gears and should be aligned accordingly. And dials are not glued to the movement. They are kept by dial feet. Some are also tied up by special screws.
Gears are never oiled. Posts and pivots are. In this particular movement most gears are made from plastic and their pivots do not need to be lubricated. I put a drop of oil on the second hand arbor only. Thank you for watching!
This is a good question and we do not have an answer for it, as the watch came from another owner. But we can see the result of something happening inside the watch. We also found a way to fix it. Thanks for watching!
You will need to remove all hands and find the midnight point which is when the date get changed. Find that spot by rotating hands and watching the date window. Stop rotating hands as soon as date changes. Then put back hands one by one, in the following order - hour, minute and seconds hands. Point all hands to 12:00 o'clock. Do this sequence without battery inserted. Good luck!
@@sanjaypatil3097 Hi Sanjay! I have an another video where all steps of setting hands at midnight position are shown. Please take a look at ruclips.net/video/Qk8yN2dTtYo/видео.html. Let me know if it helps. If it doesn't, then I will work on creating yet another dedicated video.
@@sanjaypatil3097 What movement model do you have? If it has both date and day, then it's normal, that day changes in 2-3 hours after date (which changes at midnight). So, the answer is, yes, your watch is set up correctly.

And i love how it's suddenly rain outside everytime he speaks. This guy is a sorcerer
I had a bent tooth on the plastic gear, straighten it out with the forceps. Nice breakdown.
That's great! Does tooth still work? Plastic can fail after that kind of surgery.
@@ValentechTime still holding.
Well nice and good made.
I did a similar change once in 2305, second wheel was bent.
OK good and wish you good.
Thank you!

@@ValentechTime Thanks a million for taking time to respond me very clearly and for your precious help ! 🤝
@@_Platinum- My pleasure!
Do the gears need oiled?

@@ValentechTime Thank you for that. All the best.
Love it ! where do you get the parts!
Thank you for the nice comment! Some parts I am finding in my scrap drawer, some parts need to purchase.
How on earth did that tooth get bent?
