This is why I'm not a fan of the SW200. This has happened before and Elshan had to send me a new watch. He mentioned to me this is an issue he has seen often with SELLITA.
I'll probably be contacting Ocean Crawler for a return label. I felt the tightness in the crown while winding it. Today it felt like the rotor was trying to take off and was spinning violently. It is really bad when trying to screw in the crown after winding. This is exactly what happened to my ZELOS.

The spinning rotor issue is a reference to hand winding the movement and the rotor is being turned as you wind. It adds weight or stiffness to the feel of the crown and puts strain on the ratchet wheel. If you persist to wind as it stiffens up it will do some damage.
This has to do with the lubrication of the Reverser wheels. These are part of the winding mechanism that allows hand winding the movement. As the crown winding becomes stiffer they cause the rotor to be turned as you wind. This explains the stiff winding and the feeling that the Rotor is actual spinning as you wind. If you force the Crown while winding and feeling the stiffness it will actually break the teeth on the Ratchet wheel. (as I found out). You can no longer hand wind at this point as the crown feels disconnected.
With the stiff winder, spinning Rotor or broken teeth on the Ratchet wheel, the watch will still work, if you charge it via movement on the wrist. In other words, the issue doesn't stop the watch from working. However, I wouldn't want those broken teeth doing other damage as they bounce about inside.
