there's definitely play in the rotor.... it's difficult to say -I really don't have that kind of expertise to have noticed the later style rotor (mea culpa -I must be more observant -but to be fair I don't do 70's Connies...) it could just be a replacement or it could be a sort of transitional piece with the new style rotor on the previous model movement
-this is a learning question are the indices onyx inlaid? the black looks a very thin layer -or did Omega do a thin inlay? BTW this doesn't stop it from being a very nice dial -onyx is just a bonus in my book
