Anyone who says quartz movements are not complicated and garbage needs to watch this video. That's for sure.

You know, you can also punch them in their face for that words and watch them being not able to punch you back because of that unreliable mech shit on their hand.

They are not available as new, but if you are brave and lucky enough to find a working batered watch for an honest price, go for it!

Great videos, thanks for sharing. Too bad you didn't record the reassembly part, I'm actually interested in knowing if and where you would need to lubricate in the 7a38 movement. I have a movement where the seconds and chrono hands get stuck. The battery is working and hour/minute hands move but I assume the smaller hands have dried up oil. How could you resolve that?

Thanks for the comments. Your watch would need a comete strip down, clean and rebuild with the appropriate oil, from what you say. To put new oil on top of the old will only worsen the issue

I thought you were only supposed to handle the coils from the attachment point and not from the plastic bobbin.

Do you have any tips for reinstalling that bridge with all the 5 or 6 gears under it? I've had a couple of tries but so far still no luck getting all the axles into their respective jewels, etc. Anyway, I'll just keep fiddling with it but any tricks would be welcome. Thanks... and thanks for producing your videos.
