I had the pleasure of choosing between a 5711 and 12 both in SS 9 years ago.
I chose the 11 bec it was the original design of Genta plus the fact that the 12 is almost 10k USD more expensive or a brand new Daytona 116520 (which i later bought).
Now, if money isn't a consideration, I'll still get the 5711 as simplicity is the ultimate sophistication.
