I just bought a Patek Blue Aquanaut PF factory version the case is 8.7 mm thick and the movement is decorated. The only complain I have is "Swiss Made" is missing from the bottom but the color is beautiful the Calendar font is smaller though but that does not bother me as much as the dial issue.
High one did you buy? Can you share the link to the page description from where you bought it?
Is it the 40mm or 42mm? Given that the 42mm PF has Swiss made on it I guess you bought the 40mm.
FYI:
1/ 40mm aquanauts don't all have the Swiss made on the dial, so your "issue" is not an issue
2/ 40mm in blue, if that's what you have, if a fantasy model, it does not exist in gen. The only blue is the 42mm and it's in white gold
Do yourself a favour and search the Patek section of this forum for more details on the pf. There was a review of the pf and some comparisons with others if I recall
