Broken stem stuck flush inside vintage crown
I’m working on a vintage Soviet Vostok with a 2414 movement and the winding stem snapped off inside the crown.
Unfortunately the remaining piece of stem is basically flush/recessed inside the crown, so there’s nothing I can grab with pliers or tweezers. I’ve tried very carefully using a fine needle to rotate the broken piece anticlockwise, but haven’t had any luck and I don’t want to keep going and damage the inside of the crown.
I’d really like to save this particular crown because it’s the original gold-tone crown and I haven’t been able to find a matching replacement.
Photos attached under magnification.
Has anyone successfully removed a stem broken this deep inside a crown? What method would you recommend without destroying the crown?
Thanks!
