Got a question to the technicaly savy people around here.
I heard a dangling noise in my Seiko, so i opened the caseback and saw that the rotor was quite wobbly
and the center bolt on the bearing was lose. i tightened it up a little but after a while it got loose again.
How tight can/should it be tightened? or is there some other technique to get this fixed?
its a very narrow slot screw, so there cant be much force applied even i wanted
