What size tool to open up GMT master 2?

Hi there guys.

I would like to open up the back of my GMT master 2, not really caring to go to a jeweler/watchmaker, I would like to do it myself.

I have the common screw-back opener, but obviously this doesn't work on a Rolex.

I have opened many case-backs before, so I know the drill, but what size is the back, since there seems to be several sizes for the tool?

I use the Bergeon no.5 socket (29.50mm).
