It is missing the inner track compared to other conquest dials. However the fonts look correct. Could it be a correct dial varient?

 

The text looks good to me, but I agree I have not seen this dial variant (not to mention the unusual color/patina).

 

I have found its brother on IG so looks like just an uncommon Conquest varient after all. Learnt something everyday.

 

I've seen that variant on a Conquest dial before, in fact this exact reference was the first black dial Conquest I ever saw. All looks fine and original to me.

 

I don't often enjoy black dials but this one is striking - I love the hand length and the proportion of the markers.
