Woohoo! It worked - the movement was pretty "stuck", but I managed to move it a tiiiny bit. It never really seemed "moveable" though (it was fixed in its position even after having loosened the two plates), so pushed it and at the same time fastened the plates. I just found two plates/screws, perhaps I missed something?
Anyway, attaching a pic, if anyone else wants to see where the plates are located:
A really nice bonus that came with this fix was that I also aligned the T on HUBLOT and the last E on GENEVE (had to give it a go since the case was open!). I just pushed the letters carefully with a screwdriver, added some preassure on them, and voila, now they're fine
Thanks once again for all your help!
Cheers!
