Bezel removal for battery change on (current) Aquaracer CBP1111

Can anybody advise on how to safely remove the bezel on the new (current) aquaracer quartz model? Does anybody have a link to a video showing this? I need to replace the battery on mine which is specifically a cbp1111.ba0627, but do not want to send it to a service center. I know that the bezel needs to be removed in order to remove the backplate.

This is a bezel removing tool:
The key is to grip the bezel evenly while pulling and turning at the same time.

Am I right in concluding that the back is held on with screws under the bezel?

Oh, this particular one (Bergeon 7152) goes for about $900.

Hi thanks for reply. Yes based on some research of online posts, I believe there are screws under the bezel that secure the backplate. Yes I saw that tool, but I guess I would only need a single attachment ring of the right size, so may be overkill. I could buy just a single ring with smaller hand grip which is much cheaper. Do you know if a simpler tool such as a good quality watch knife (eg bergeon) is worth trying?

Have a look at https://tagheuerforums.com/threads/...ack-off-the-new-aquaracer.136527/post-2438250. I mention removing one with a knife (and what goes wrong).

There are some "Universal" attempts that are way cheaper, more like a hard rubber "tire" for a caster. Whether these work or not is anybody's guess. I would not recommend a knife.
