32xx movement problem poll and data thread

Is that what you have to do?

Barely reach tolerances? What are the amplitude tolerances (H- and V- positions) after a service? I am curious to know these numbers (for my 32xx watches, two need a repair).

Bas, many thanks for all these information and explications, very interesting and much appreciated.

Correct, parts that did not show any sign of wear/deterioration at all that are replaced out of desperation to reach a minimum amplitude off 200 degrees after 24hrs.
A 24 hours test can be simulated by releasing a couple of ratchet wheel rotations.

This problem runs so much deeper than just migration of lubricants and a pivot that occasionally wear out prematurely.
