Movement removal from case enclosure

[SAMyMAS]

Hello All,

I am having difficulties removal the Chinese movement from Kenneth Cole watch, A126-12 KC1920. 

The movement is inside a plastic enclosure/frame. I have removed two screws (green) to no avail and as you can see there are two more (red) but unable to unscrew them as besides them a metal pin, which I suspect is preventing me undoing ones. 
 

I would appreciate if someone advise/point me on how removing it.

P.S.

The movement has some issues with the second hand constantly loosening/falling off. I will try to fix this or use one as testbed to learn disassembly/assembly. I believe the movement is Seagull ST-1812 (TY2661)

Is this part of the case/surround?

[SAMyMAS]

Hi @AndyGSi, thank you for your prompt reply. This part fits into the case, without any fasteners and sits quite tight with the stem/crown installed and the  case-back screwed down.

The clamp I've shown in the photo is this not screwed down and then is it removable?

I see what you mean now. Let me check. I thought this is part of the movement.

[SAMyMAS]

Yes, it is part of the plastic case/surround. I scraped the paint of it and cracked the other one. It would appear I have to disassemble movement as is, in hopes of getting it out, and try not to do too much damage.

So with tab on the back then it must come out of the front.

You do know these screws are to remove the dial?

You turn them to the flat frees up with the dial pin.

Edit

Just realised what the red and green referred too in your original post as the arrows weren't obvious being so fine.

Spot on. The movement came out at the front with the dial in place. I didn’t realised the pins were from the dial and certainly did not know about the screws function in securing the dial release. Managed to remove the dial but broke one pin though and damaged the another. This shouldn’t be a problem, I have new spares to install. Thank you @AndyGSi for your continued help.
