Ah, it seems Stephane did confuse you.
With modern Subs (16610) you can't really do the same mods as the vintage Subs. The Noobmariner is a modern Sub and as such, you can't change the bezel/crystal assembly with genuine parts. Besides, you don't need to as ... well, lots of reasons that this thread has nothing to do with.
I think, in principle, you're right. All modern Subs can be modded to get rid of some of their defects, but none can be modded to make them perfect. This is due to the dimensions of the Rolex movement at the heart of the watch. The rehaut and crown position can never be identical to the genuine as long as the counterfeiters are using an ETA 2824/2836 movement.
