Flyback PP8890 similar 7750 minute reset problem

[lhm74]

Hello all I have made a revision of a Paul Picot PP8890  Flyback chrono (small differences to ETA 7750) and I have the problem that during reset the minute hand will not reset to zero but each time in a different position. I think the problem can be that because the minute hand is not fixed directly to the chrono minute wheel but recive the movement from intermediate wheel, the axial distanze of the intermediate wheel is not correct and so during chrono function I can have some slipping problem.
Thanks for helping

In 7750 the minute counter hand is directly placed on the minute counter wheel pivot.

Have you checked the hand is secured on the pivot.
