Oscillating weight spinning while turning crown

[candide2424]

Hello,

I have a problem with my eta 2846.

Occasionnally the oscillating weight spins while one turns the crown. At this time, turning the crown is more difficult. After a couple of turns, the oscillating weight stops and turning the crown is really smooth.

Any idea ?

Thanks,

I have got a couple of modules. I will swap out current one and see how things turn out.

I swapped modules and movement works fine.

Thanks!!
