SW200 Rotor Problem


I have a SW-200 in an Aquanaut. The movement has been running great with the exception of a pretty loud noise coming from the rotor. The noise can be heard just when wearing the watch, either when the rotor is moving or when the watch is shaken lightly on the wrist. I have tried removing the rotor and the issue goes away, no noise at all without it. Has anyone else experienced this problem or have any idea what the problem could be?

I have included a video. The audio has been enhanced so that you will be able to hear the issue and the shaking is much more vigorous than the watch would usually be subjected to in the real world. Thanks

The video is not very clear, is it like there is some play in the bearing of the rotor?
