I reset the date on my quartz SMP yesterday evening and woke this morning to find it had stopped. I released the crown slightly and it started ticking away again.

Now , my first thought .. the crown was overtightened .... but I wouldn't consider myself heavy handed and I'm careful about over tightening but obviously when the crown is screwed in to a certain point it stopped the watch, not immediately but after an unknown period.

My questions .. what is the cause of this? How would the crown stop the movement? ....and also, is this common or it is a fault with my watch?

Any help/ comments gratefully received

The battery was replaced last year sometime .. just to point out
