It is clear that it is an enamel dial.
Like you this is the only Duometre I accept in this smaller case.
The lunar disc and phase is a plus, I agree on that point too.
Well, I thikn that for an owner of the black dial ,the dilemma exists.
For those who don't own the black dial, it is really a matter of taste. Personally, I would go for the enamel, but I have a big weakness to fill, with enamel dials.
Thanks for your input, Mo!
