Helicopter Effect

I am new to mechanical watches and while winding I am having an issue with the rotor spinning wildly. The crown begins to rotate the opposite direction of normal winding. Looking for someone with some insight on this issue.

Hey JMC,
sounds like a movement issue. I had something similar a few years ago with a different brand’s model. They spun wildly in reverse, mangled the hands and the movement went as well. I would contact DIY customer service directly.

I just finished building my watch, I hope things go better for you.
