I know nothing really about these but do own a 7262 (of which I also know nothing about) that has a similar black dial. It's the deep glossiness that attracted me to it and when I look at the examples you are showing none of them have that.
So I'd say if a very even matt they are likely redials, 1 and 2 for sure, 3rd one I don't know, but the text doesn't look so good to me. Sometimes glossy black dials dull and fade through factors such as some kind of moisture ingress but it's usually much more uneven and there can clearly be seen that they had originally started out with a more lustrous finish.
