Dear

After I haven't worn it for a few days, I rewinded the watch and since then, it runs too fast. In 24 hours, the clock was more than 3 hours faster than it should.
I always wind it completely and had no problems before, just since it had been unwind completely.
This problem also occurred when I got it from the factory and then I've also he'd to send it back.
Can you give me some advice in why this happens?

Thank you and kind regards
Jürgen
