from what I could observe and read, in my opinion... the best white dial is the CF without a doubt, the best black dial is BTF because it does not have the numbers of the sub-dials close to the edges, but well centered, I also seemed to see in the sub-dials also a certain soleil effect like on the gen, something not present in the clean. also on the movement there is a very good SH4131 against a DD4131 of which we have high expectations, but of which we still do not know much... I, personally, wanting a black dial will wait for further comparisons and developments. but in the case of the white I would immediately go with CF
