hello all!

I own a gv2 stadium 4009b watch and am new to watch repair. My question is this: does anyone know how to remove the movement (eta 2836-2) from the bloody case? There's a retention ring held by 2 screws that when loosened rotates the ring. There are 2 screws that also secure movement to the ring...but i can't remove the ring nor the screws holding it because it is under the case. The watch appears to be in 2 parts: bezel, glass and inner rim of dial. the actual dial seems to be independent of the former. Not to want to force things do i have to seperate the bezel to remove the movement? no videos on gevril repair so asking here...thanks for any input. I'll attach pics if helps
