Fixing Date Adjustment and Broken Gear Problems in Miyota/Citizen 1M12 Watch Movement How To

Описание: The video shows how I fixed a date adjustment problem in the Miyota/Citizen 1M12 quartz watch movement. After disassembly I found yet another problem with a plastic gear having two broken teeth. This gear controls an hour hand which will stop at some point due to the broken teeth. As for the date adjustment issue, I found the yoke out of it's position. This also caused the stem to be loose.

Thank you for watching and please give me a thumbs up!
