·I have a calibre 11-i that I recently performed a service on. Once the watch was reassembled I noticed a rough feel when manually winding. I was wondering if this is the norm for this calibre. On a technical note, the reason for this roughness is that the wig-wag pinion remains engaged to the winding-up wheel and/or the reduction gear. This causes the clutch on the coupling wheel to slip (as it should). The clutch slipping is the actual roughness that I feel. Removing the micro rotor, I can move the wig-wag out of the way and the manual winding is quite smooth. It is quite possible that this is perfectly normal for this calibre - but I'm not sure. Any help appreciated.
