You are wrong. They are gloss...
But because the dial is not as black as eg a sub or gmt it sometimes looks matt...
The guy who did the (gen) Jacques Piccards DSSD for Philipp Stahl told me this. He has held 87 of them...
Some pictures of a gen DSSD dial
You are right about the MK1 an MK2 though...
Dial is gloss.
It sometimes looks matt because it is less black and more grey than other dials (eg Sub and GMT). But it is 100% gloss.
Gen insert will never fit a rep, totally different.
Dial could well be gen. Lume color is blue but often it turns out more green on pictures.
I think that is because the gen has AR on both sides...
Here on RWG and Repgeek people tend to think the gen only has Ar on the inside.
