Congratulations again, Daniel, and great comparison shots! That dial alone is a real jewel, but the whole watch was put together with a lot of thought and care. I really don't think you could do much better, short of buying a gen.
Regarding DW's dials, his final batch was a case of one step forward, two steps back. The coronet is an improvement over previous efforts, and I bet it looks even better on the wrist than in macros (which show that the definition of the tines and sharpness of the pearls have some way to go). However, DW's dial supplier dropped the ball on the subdials: The concentric circles reach all the way to the outer edge, while the conical "dishing" in the center has been replaced with a flat plateau. Nitpicking, maybe, but I think it looks weird from some ways off. Check out a couple of DW's 7750 dials from two years ago. Even the one with crap printing gets the registers right:
The 6239 dial is the newest of the three. Pretty nice, except for the pronounced ring in the subdials, and some tatty hour markers. If you check out some of the older DW/V72 builds, you'll see even more variations in dial quality.
