Removing automatic movement on a pam

[pybu15]

I recently purchased a 233 from King. I would like to remove the AR and in order to do so I would need to remove the movement and dial. The movement is an Automatic Asian 21J. Does anyone know how to remove the crown from the movement. I can't find the screw near the crown like I would on an manual winding movement. I am wondering if the complication due to the power reserve is an obstacle to removing the movement and dial.

Thanks for your help.
