Wow, that does indeed provide the definitive answer!
In the past I could have sworn that the bezel was just a polished detail on the case, but clearly not. The junction is extremely fine - practically invisible even with magnification.
The question now is whether the bezel needs to be removed before removing the crystal, visa versa, or if it doesn't matter. It sort of looks like it might not matter, although removing the bezel without removing the crystal first could be difficult without damaging it, given the lack of a notch. On the other hand, if the bezel was removed first you might be able to get a better grip with a crystal removal tool and there would be less risk or scratching the bezel. Maybe back in the day it would be usual to replace the bezel and the crystal at the same time?
