I think this depends on the movement...for example...to change date on my vostok amphibia...i need to move the time from 12-8 counter clockwise and then clockwise...to change the date,however this doesnt effect the movement with regards that it can get spoiled...however i have read some movement like old winding watch, the movement are kinda tricky and can get spoiled...but i never experienced it b4...maybe other sifus got better explanation
