Where can I download the C07.121 movement decomposition diagram? What is the reason why the movement of the watch is particularly low after the watch is cleaned? Do the plastic parts inside the movement need to be cleaned?

Yep, basically the same principle as for watches with a Swiss lever escapement. The position of the hairspring collet needs to be adjusted/rotated on the balance staff such that the impulse jewel sits perfectly at rest between the banking pins when there’s no power to the pallet fork. On some escapements, there’s an actual beat adjuster, but I’ve never seen one on a clock.

Nope, only on several Japanese automatic movements. I can't remember if they were all Citizen's. There might have been some Ricoh's or Seiko's with a simular construction as well.

Correct but we only see at X1 magnification. Not visible to the human eye. -

Thank you everyone, I have located and bought a part, I appreciate all the replies and have really enjoyed the process…… I’ll let you know which parts I break during re-assembly and we can do it all again 😂😂😂 -

BOUGHT! SOLD! PURCHASED! Un-real, with everyone’s help and information not only did I get a chance to see how powerful a forum could be but I’ve learnt ALOT about movements share/swap uses/information which has resulted in finding and buying the part! Thank you very much mate
