Well, to me, the MBW dial is far from the MKIV dial due to the manner in which the lower hemisphere fonts are printed. MKIV fonts are done in a series of dots, as pictured in my prior posting. Perhaps from a distance it appears close/similar, but they are certainly no where near being the same in regards to detail.
As for font spacing... The biggest alignment issues are with the SEA-DWELLER/SUBMARINER 2000/2000ft = 610m lines. Compare these lines with the MBW, and they're off.
Personally, I think the MBW DRSD dial is somewhere between MKIV and MKV... Not identical to either but has a mix of characteristics between the two.
The white dial stands to be the closest, but that's just my opinion.
We do strive for perfection... But, the only real way to achieve it is to drop $9k US for a genuine DRSD dial, or simply buy a genuine 1665 DR (to which there is no substitute for). Still... I think we can both agree that building these watches is what really makes this hobby fun...
