Knocking on wood, i have no movement troubles with all my watches.
My Omega have a strange crown feel, so i put it always on a winder to avoid unscrewing.
I am afraid to buy another watch with a screw in crown.
I never over wound a watch, i always think when wind a watch, ‘ i must stop now’ the mainspring can break.
Waiting is horrible. I hope your watch comes back without any troubles.
