It's not the back that's in question (besides, a caseback would be easy to replace if you could source one), but rather, the dial. Specifically the amount of the "8" that is cut off at the top by the small seconds subdial. Typically (read:always) up 'til now, we have noticed the flaw in the rep is that there is much more "8" than there is on the gen. This watch brings that assumption into question.
