Movement stuck

I’m trying to pull the 3135 out of my submariner case, but the case screws will not budge. I’ve tried the proper screw driver, which slots well, but bends by the point I apply enough tension to break loose the screw.

Are my drivers just soft steel crap?

The Marine in me wants to soak it in WD-40, and choose violence until the little bastards move. The adult who spent money on the damn thing knows that would be a a bad idea. Where do I go from here?
