So long story short, my rotor stuck cause of a screw jumping around the case, took it to my watchmaker, he managed to put it back where it’s supposed to. He did state that many screws in the movement were loose, he did tighten them all and did pressure check to 10 ATM after repairs, all good now!
I get the feeling this is a common problem with clone movements. So many fake screws that are just there for decoration but not properly affixed. I had two fall out on my PAM512. I was lucky and caught them in time before they got tangled up in the balance wheel.
