Sorry I gave you a bum steer. I was assuming that you simply wished to change crowns initially and that you were dealing with a cal 565 which has the option of the release button on the movement. But the system is completely changed when the case is a monocoque.

I'm assuming you used a proper crystal removing tool to remove the crystal because you'll need it to replace the crystal as even pressure is required around the crystal rim. So to remove the crown, you normally use a crown lever that allows crown and the detachable part of the stem to come off together. Then you use a pin vise to remove the crown if that was what you intended to do. The detachable part of the crown stem is split so as to be easily returned to the movement part of the stem when re-assembling. So after removing crown and detachable part of the stem, you should not see anything sticking out of the crown pipe.

To remove the movement you need to carefully rotate movement and dial together anti-clockwise until 12 oclock reaches where 11 o'clock normally sits. Again, if youre not careful you'll damage the dial. After rotating the movement and dial to position, grab a soft cloth in the palm of your hand and turn the case upside down and movement and dial should should fall into your palm.

If there is stem still poking out of the crown pipe you will need to wind the crown back on if you can. Then use some tool that does not put pressure only on one part of the crown but allows more even pressure to be applied. Gently but firmly lever the crown and detachable stem off. If that doesnt work, get some help from a professional.

I admire your courage :)
