No, I am referring to the metal circle indices around the lume at the 1, 2, 4, 5, etc. It is considerably thinner on the newer gen dials. I am not sure where the change took place but I compared mine to my friends newer gen and it really blew me away that the dials looked that different. His had the newer arrow second hand and the thicker hour & minute hands also when compared to mine.
My buddy even noticed it and he is not psychotic about this sort of thing like I am.
