Have to disagree on it being aftermarket. The problem is as you say yourself "the more you look at it". In other words, because there are some blatant details here that fail the 'smell' test, it almost follows you start to question other aspects of the dial.
That said, I think the recent proliferation of so-called tropical dials like this in almost NOS condition (which itself should scream out given how genuine tropical dials gain their patina) rings alarm bells and I know of at least one major vintage dealer who, without concrete provenance, won't touch them with a bargepole.
Whatever the reality and indeed true value, the fact is it's not a particularly nice dial either way IMO.
