As I understand it, the bezels are press-fitted and I was told that there is a chance that once out, it may not fit back in.
I pushed the crystal out with a crystal press and it bent the tabs on the way out. After I got it back from Taka AR, I bent the tabs out a bit further with a pair of pliers and fit the crystal back in and used the back of the pliers to push the tabs back in. It would be better to use a cloth to cover the pliers before this. I didn't and there are now light teeth marks on my tabs which can probably be polished out if I'm not lazy.
