That is a very good looking watch! I have never owned a “Modern” ( post Philippe Stern) Patek Philippe. All of my watches are from the Henri Stern as well as the Philippe Stern eras. Is the 5320 a popular watch? I have heard that Sports Watches are the thing currently in Vogue.
Also... being a very modern watch, I am curious about the actual time keeping ability of the 5320. Do they keep great time (relative of course to a mechanical watch) ?
