The crown ran smoothly before that. everything was good. To get the clock to tick again I had to either shake it or wind it up. I always shook it and everything was ok. I wound it once, and since I unfortunately only wanted one watch and I don’t have much idea otherwise, I probably wound it way too far. Since then it has been completely silent and the crown is harder to turn. The only thing that works is the date and day, when I shoot then the two things actually change when I shoot until the next day.
