Nice to see JLC returning to the black dials they used to make in the early 2000's. I miss those!
I feel though that the black dials ones are nice as a "next JLC" dress watch - maybe one's first JLC being a more versatile lighter coloured dial, then the "next" one being the darker one. For example, one might start with a Reverso, RDM, or a Master Control as the first, then for the 2nd, follow-up with the dark MUT Moon. Light and dark JLCs for all occasions!
Then again, if one wanted both a light and dark dial, one could always get a Reverso Duo as one's first...
