vostok 2416b never fully wound

[cp5184]

I got a komanderskie with a 2416b, and I wind the crown over and over and over, more than 30 times, and it never becomes fully wound... Does anyone have any ideas? Is this normal?

It's normal. In automatic watches there is a special mainspring end, that slips a bit on the barell wall when it's wound fully. Otherwise the auto-winder would try to wind a fully wound spring against it's resistance. It would be like pressing the corwn in winding direction against the resistance in a handwind watch - it can damage the movement and causes knocking of the balance wheel, so to prevent it - this system was invented :)
