How do I get this (still unknown) movement out of its case? Any advice?

Hello Together 

I have mainly worked on much bigger movements in the past 1.5 years. Now I've come across this lovely platinum case watch which doesn't work. I'd like to give it a closer look, but sadly, I can't manage to the get the movement out of its case. There is half of a crew head visible at 1. o'clock, but it did not turn, applying just light pressure with my screwdriver. Is turning that screw the right thing to do here? 

Thanks in advance for your time and advice. 

Sincerely,

It will lift straight out, could be a pretty snug fit, but just be patient and lift a little all around.

@nickelsilver Thank you very much for your fast reply and the correct advice. I've managed to safely remove the movement from its case. Thank you very much!
