Is the rotor stuck? What about giving it a Big swirl - see if the rotor moves ( 312 have crystal caseback - right??)
Might just be lack of Oil in the rotorbearing. That was the case with my 187.
You Can find a tutorial about it.

I`ve replaced ST2555 movement 3 times in my Pam 312. My watchsmith told me that there`s a gear in the movement which is a total crap. He replaced it with solid, old Poljot gear.
