Well, IMHO the nautilus was meant to be a sports watch that's why stainless steel should suit this timepiece better, i think precious metals such as gold and platinum should be left for dressy watches as a symbol of classicism and elegance or wealth, of course this is just my opinion, i own the 5712/1A since a couple of years and it took many showers and dips in the ocean with no issues, good luck with your decision.
