Tissot 31-1 oscillating weight bearings?


Recommended Posts

Have a question about the oscillating weight on a hammer automatic . The weight rattle and making noise .  If the bearings worn i can replace them. But if the pivots on the arm that sit on the weight worn.  Can i replaceable them or the axle? Haven't seen any such parts as spare parts.  http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Tissot_31_1

A donor movement will be your best bet

Not sure that is an option for the owner. Isn't there anything one can do? Don't have the movement or the watch here just yet. But i have seen it before when working on bumper movement like the Tissot 31-1  . If i buy a donor i can't  be sure that the bumper weight is  okay? Think the watch works okay but he says it annoying to hear the sound of the bumper is hitting the caseback or the movement plate.
