Sometimes it gets really frustrating with these reps. I get asked all the time which is the most accurate. Truth is that each model is just as close as the other, but each has its own unique flaws.
Serie Speciale - Not brushed
3-6-9 - Datewheel/Window, inaccurate slide rule (Latest versions)
12-6-9 Two tone - wrong caseback, wrong hand color
All have wrong datefont, some are closer than others however.
None have proper AR, some have light single sided coating.
Now if you are not satisfied, for $888 Josh will sell you this near perfect Serie Speciale. It says that it has AR, but I doubt its on par with the gen. Beyond that, the AD is your next stop.
