Yes BT, the MBW rehaut is deeper than gen, BK said 0.1mm deeper, you can notice it also from the stronger data mag effect.
Actually what bother me most of the MBW/TW is the conical rehaut.
Not like old CN sub, but still wokky. Noob is correct in this way, but too shallow.
The difference that can justify a 500$ rep is the 1:1 gen case construction, same gen bezel assembly, crown and tube OEM specifics, so a perfect base for modding.
At the beginning I was looking for a OEM case too, but 1400$ is definetely not worth for a modern Sub.
@JoJo35: all the gen parts fit without any mods but the bezel, that needs a little bit of case reworking (my watchmaker did it)
Gen bezel fits the case, but too tightly and wouldn't turn. A little bit of sanding (of the case) made it work correctly.
