I nearly forgot about the very first question ^^
I have 3 manual watchs and all share the same "feature": as soon as I wind the watch, I cannot pull the crown out anymore. I have to slightly "unwind" (technically it does not unwind anything but you get the point) to unlock it.
And no, they are not supposed to be screw down crowns
😁
Anyone also experienced this and any idea of what could be the cause? (V92, 930, and GP12.3 in case it matters)
I am guessing that the torque applied when winding creates a kind of lock between the winding pinion and the sliding pinion but I do not understand why exactly... (the 930 is in deep need of service and even more - but the 2 others were taken care of recently - at least supposed to be)
