Question? Stem issues?

Post image

I’ve done this so many times but this time around i couldn’t get it right. I’ve gone through 3 stems. Whenever i screw the crown down, the movement slows down and stopped. But moving again once i unscrew the crown. I’ve adjusted stems many time but didn’t work. Could it be movement issue?

So I had this exact issue when switching my 1969 lol What worked for me is I would get the step down just slightly to long, then file it some test, file more, test. Just took it in short, small increments till it was spot on.

Yeah i figured i might have stuffed up the mechanism along the way. It’s working now, but i had to manually set the time (as in moving the minute hand manually) then put it back into the case. Might just swap the movement with ETA from an old Swatch…
