It's not for me. Take off the Patek branding and to me it would have absolutely zero appeal, especially at the price.
I appreciate that I seem to be in the minority, as the aquanaut certainly has its loyal following. It's rubber strap and tire track dial aren't at all what I envision when I think Patek. The stainless case is said to be scratch prone, and the Arabic numerals and hands seem more suited for a watch not even one tenth the price. I want to like it, I really do, I just can't. Maybe my tastes simply haven't sufficiently matured...
I apologize if my candor is offsetting, but I took the OP's question on it's face, otherwise I'd simply refrain from the love fest.
