panerai blue dials are a hot item lately.
but this is the big decision for you - classic, historical, DNA of 372 versus super mod, titanium on bracelet?
i think most here would say 372 if it'll be your first or only cause it's got more of the look and feel.
also pre-owned 372 may be worth a look.
not sure what the 733 goes for or what the market will be, i would maybe call some other boutiques to see if they all have them or if there's a waiting list - that might help you gauge interest and potential resale.
either way though, you can't really choose wrong here.
Mike...NYC. My collection so far is a 312 and some cool straps.
