Had some weird stuff go on with my SMP lately...I fully wound it before I slept and the next day, the watch was running very fast. I read that the hairspring can get hung up on something causing erratic movement. It did look a little off to me. I tapped the watch a couple times and it seemed to fix it. I wound and set it and its ok now. Another thing. If you creep the crown back the seconds hand will totally stop which means the hairspring also stops. How is this possible with a full wind? Both of these just started the last 2 weeks after wearing it for 10 months almost daily.
