Through the front? Is there a removable bezel holding the crystal in. Remove the crown and stem, remove the bezel and crystal.
Also looks like two retaining screws, one at about 7 and the other hidden by the rotor.

 

Push down on that and pull the stem out, if the movement doesn't just drop out after that you may need to go through the front

 

Thanks, I got the stem out as described but put it back in after I couldn’t remove the movement. The internal “brass” lip that you can see at the bottom of the pic, surrounds the inside of the case, the dial is bigger than it so will not drop out. I looked at the bezel and I wouldn't really see if I can remove it without potentially damaging it.

 

Have a close look around the edge of the bezel, especially at 9&6. Often you will find a small undercut where you can get a case knife in to pop the bezel off. You may need to clean around the bezel edge to see it

 

Ok, thanks. Will take a look 👍

 

After looking more and more at this I'm not fully convinced its a front loader, you have a case screw at 8 oclock on that photo, I'm guessing theres another under the rotor at 4.
the bottom of the case is a cut out,I can't tell if theres one at 12 oclock because of the rotor but if so I would try lossening these and the rotate the dial in the case so the screws align with the case cut outs...... If I'm right it should then drop out albeit abit rolex style.

On the other hand I could be completely wrong

 

No actually this makes no sense looking again, I'm just perplexed by the cut out at the bottom six oclock one.
I do think they are case screws tho, so I would loosen (not take out) and give themovement a wiggle, if it moves more in the case then your onto a winner, ...if not it is a front loader and do them screw back up

 

If you look at the size of the dial there is no way it comes out the back, it is far bigger than the hole.
