I got a new PRX last week and set the correct time. I've wound it a couple of times in the last week, but didn't put it on again until today and noticed it was 5 minutes fast. Does that seem unusual to people? I don't live near anyone that services Tissot watches (at least not according to the Tissot website, haven't checked for other Swatch Group service centers), so I was wondering if anyone has any ideas/suggestions before I start a mail in warranty claim. Thanks!
