Gents, I dropped my watch the other evening. The reset on the chrono now doesn't work correctly. The watch has a 5100 movement, and when I leave the chrono going for a few minutes, I have problems getting it to reset to zero when I stop it. It takes several attempts of starting, stopping and resetting to get it to finally zero. Does anyone know a good repair shop I can send it to? A UK service centre would be nice!!!
