Not consistent as true patina would be through out the dial. If you search "Tropical" through out the forum using the search function in the upper right corner of the website UI, you'll find a wealth of examples that show how proper aging and discoloration can bring value to a piece.
This should be passed IMO due to lack of consistency, as another user mentioned it looks as if someone already tried to take on the cleaning challenge and failed. Missing factory indexes or signatures are of concern as well. All mentioned by previous posts, best of luck in your search!
Happy Hunting,
