I would like to ask everyone, does the 9906 movement have over-winding protection? I can't find any information about whether there is over-winding protection in the manual.

Yes, it's called sensory tactile feedback.

I have a speedy 57 with the 9906 movement, I don’t know if there is over winding protection but what will say is that it is very obvious when the watch is fully wound, you’d really have to be making a concerted effort to over wind. It’s not an issue.

Yes, when I was winding it, it was not until I turned it idle at the end that I realized I had over-tightened it.

What makes you think you over-tightened it? I have noticed that this is only a concern with people who have no experience with watches. Once you have wound a hand-winding watch a few times, you realize that the whole notion is nonsense.

Overwinding protection is only needed for automatic movements.

Sorry, I don't quite understand the internal logic of what you are saying here. You have accepted JiminOz's point about "sensory tactile feedback" (although I'm guessing with limited tonal sensitivity), but no person who has physically wound a watch would feel "idling" and "over-tightening" at the same time. Please describe your experience in a bit more detail.

The over winding protection is that once it is fully wound, you can’t wind it any more…

About 300 years ago, overwinding was an issue. Then the safety click was invented. It lets you wind the mainspring until you can't and then relaxes a bit (while the barrel rotates back and the click grabs). Before this invention, it was possible to damage a watch by overwinding.
