I know you worked there, but.....
The hardening process is not the DLC process. The hardening can happen without the colouring.
The top bezel of my Alt1_P is definitely hardened, it is way tougher than "normal steel". The MB series was sold with "hardened case" and as the barrel is aluminium, only the front (and caseback?) can be hardened. I was sure the same hardening was also used for the S500.
At least originally, which had all of the "toughness tech" like the movement suspension, that the MB was designed with.
