From my side, I prefer the black dial and blue sub dials version.
First, this colour combo is quite unusual and the nicest for me among the three versions. It could be considered as a “BB (Black/Blue) reverse panda” which is pretty cool no? 😋
Second, as I could be turned between the 38 and 42mm version, I think I could go for the latter one easier thanks to this mainly black dial which reduces the perceived size.
Third, the “Clous-de-Paris” dial pattern and the sub dial circular one is, maybe, better enhanced with this version. At least for me.
Any picture of the back and the movement?
Best wishes
