If you have a manual watch, it needs regular winding by turning the crown. Automatic watches, on the other hand, wind themselves as you move. However, if they aren't worn for an extended period, they can stop. Try winding your watch or wearing it for a day to see if it starts ticking again.

Sometimes a watch face can be too damaged, and it is important to recognise when this is the case. If the scratch is too deep and cannot be removed through polishing, consider replacing the watch crystal. You can do this by taking your watch to a local watch repair shop or returning it to the manufacturer to replace.
