The WM9 TT Sub was the best in many respects, but it's shortcoming was the dial which as nice as it is, isn't even close to the candy cobalt blue of the gen. The MBW version (with its errant left of center "Swiss Made") has a near perfect match for color. Unfortunately, the maker of the MBW is out of bezel insert and has been for some time. Best option would be buy a bezel insert-less watch and get a WM9 insert from BK. Still left with bare SEL sides, but there's always a trade off on the TT. The dial color to me is more important.
