Thanks for the info.
In the case of CF inserts I think it might not be a big problem since it is taped onto the bezel instead of press fitting. The insert can be lastly stick onto the bezel, having the full bezel assembly being installed onto the watch already, with the perfect orientation of the triangle pointing straight at 12, right?
Exactly. If you didn't see my previous post about doing this, here is a re-post.
They used the standard double-sided tape ring, and a new one should be installed for replacement. They are ultra strong and refitting an insert with one can be mildly challenging because the insert can stick before you want it to, and be misaligned.

Note that these tape rings don't always fit the space in a bezel well perfectly. They can be cut into halves or thirds or quarters as necessary to be equally distributed around the well. Coverage does not need to be continuous. Care should be taken not to let the outer edge of the tape ring ride up on the wall of the bezel well. Some folks may prefer to attach them to the insert first, I find it easier to control their placement by attaching them to the bezel well first. The tape rings should never be touched with fingers, the adhesive becomes compromised easily. I use two pairs of tweezers. (Edward Tweezer Hands, lol).
To ensure the insert is aligned perfectly on reinsertion, I put a small thin obstruction across the bottom half of the bezel well. A strip of a dial protector works well for this. You can also use pegwood or a toothpick but be careful not to let it roll out. Then gently set the top indicator (24 in this case) to 12 o'clock. Then you can take your time evaluating the position, get a second opinion from someone, take a pic, etc. so you are certain it's right. If it's not, the insert will lift out easily from the bottom.
Using this technique will keep the insert from falling into the well misaligned, which means starting completely over with another removal, re-taping, and reinsertion. Not fun trust me, haha.
One other very important point about doing this. The rep factory tape may be thicker than the 3M. So I always test fit a 5mm or so arc of the tape into the well and place the insert. I use the obstruction technique for this too, or you can put a piece of scotch tape on the backside of the insert to facilitate pulling it back out.
If one layer of the 3M tape is insufficient, I add a second layer and reassess. I've used as many three layers on some installs. More than that and I switch to a different tape, use a spacer, or an epoxy glue bed, etc.
