I've just got my Tag Heuer Carrera with A7750 inside. When I start the chrono the hours are not being counted and the hour dial at 6 is not moving at all. Is this normal or is it an error on my watch?
Sounds like yet another crappy A7750 movement!
Let it run a while, though, just to make sure. Remember it will have to run at least an hour for the hour subdial to change.
