The chrono pusher decided to come off one day without me doing anything to the watch. All the parts are there, including the spring.
When I try to put it back on and turn the outer turner thing, it goes past the bottom of the pusher, showing grooves (you can make this out in the third picture). And it never stops turning.
The pusher does not go all the way in. When it's on, it's longer than the bottom pusher.
Does anyone know how to fix it?
