Jump starting a dead automatic.

To start, here's the watch we're talking about.It arrived in non-running condition but I do intend to keep it. It's not a rare or valuable vintage so I'd like to use it as a learning experience. I have managed to pop the crystal/bezel and run into my first issue. The crown stem goes through a hole in the case and the movement won't come out. How do you separate the crown from the movement to remove it from the case?Once it's out, I'll post photos of the movement and take further suggestions.
