I've used super glue without issue, you just need to be careful and it depends on the type of insert you're using. I'm a serial insert swapper and since it's much easier to swap a bezel than an insert (assuming you have the right tool, i.e., a bezel remover), I have a number of extra bezels with inserts permanently glued into them. Aftermarket inserts are almost always thinner than factory stock, so getting the insert to sit flush with the bezel rim becomes a challenge.
I used small pieces of 316L wire inserted perpendicularly between the bezel teeth and the underside of the insert to force the insert up to flush. Then I painted a thin bead of super glue in the gap, removing the wire as I went. The fast dry quick adhesion of the super glue was ideal for this application. It also helped that the the bezel was off the watch.
