My Pam is also a asian movement one and so far is running perfectly. I don't think I will be buying any swiss unitas movmement Pam's any time soon. Nice watch by the way and a nice strap to go with it.
I had also decided to buy only Swiss movements. As this PAM has been running perfectly I´m not that sure anymore...the only difference in operation seems to be a little coarseness with winding.
