Hello guys. I recently acquired this piece. Its an 1983 16808 blue with tropical dial. I have seen many dials that turned purple for this reference but nothing like this one. Its more green than blue which makes me wonder if its authentic. At first it seems all the fonts check out all right, but I haven't seen as many rolex as you guys do, so I would welcome all your opinions. Thanks in advance.

Here are a couple close up pictures. Due to the reflective nature of the dial, its hard to capture with my iPhone.
