Hello fourmers. Just a quick question when manually winding the miyota autos. With the Swiss auto's you can hear a faint clicking noise when it is fully wound, how can you tell of the Miyota is fully wound, and is there protection for over-winding?

As I understand it, auto watches have a clutch that prevents over winding.

I have hand wound my 8926 several times and although there is a slight resistance after winding for a while, it is nothing like a mechanical watch.

I have given my 8926 sixty winds without any ill effect.

That's my story and I'm sticking with it.

When any of my Miyotas have been sitting for several days I'll wind them 40-60 times. I have not encountered anything like a clicking or resistance, but I also haven't had any issues with the watch. I just take it for granted the clutch kicks in.

You can wind it forever if you want since it can't be overwound.
Otherwise they would tell you to take it off after a certain amount of wearing to prevent overwinding.
I have found that the Miyotas have a less "confident" feeling when being handwound than their Swiss counterparts.

Yeah, sounds good. I was just checking to see if the Miyota gave any indication that the mainspring was fully wound during a manual wind.
