Opening a very small pocket watch

[SpanishApprentice]

My mother recently found it at my grandparents, we have no idea where she got it. It's the only mechanical watch she had.

It's not running, and I want to open it to examine the movement, but I can't. I have tried with the Bergeon 4932 and a sharp knife, and I haven't had any luck.

I have checked all the borders, and I don't see any notches to make pressure. Any advice? I always struggle with push-fit casebacks.

Here and here, looks like prise points.

I just managed to open the back, and you are right, the back one is the one you pointed to.

There looks to be 2 seams on the back so not sure which is the actual split.

It was the closer to the center, I thought it was the one on the outer side, but it was not. Is it possible the bezel is not removable? I have been looking at it from the inside, and seems like a solid piece
