I've had an SMP Chrono for about a year, and, recently, after some swimming in the tropics, it took on a small amount of water vapor. After reading the horror stories on this site about the NJ repair facility, I decided to send the watch to OWSA in Philadelphia. They had the watch for less than 2 weeks, repaired it under warranty, cleaned and shined it, and I generally couldn't be happier. I've noticed, though, that the rotor doesn't seem to spin as freely as as it used to. The merest movement of my wrist used to set it spinning for several seconds, and, when bored at work, I'd involuntarily start doing slow karate chops with my left hand, listening to the watch wind. Now, it only seems to spin freely once or twice, if the angle is right, and then it doesn't do anything at all. The power reserve is at least 10 hours, although I haven't let it wind down to see how long it really is, and it's keeping great time. Is this an issue? Should I stop karate chopping at work? Most people think I'm nuts in any event. Thanks much.
