However, its simplicity of the dial makes 5711 less attractive when compare to the dial of 5712...more complicated, less balance, but very attractive.
That's my opinion only on 5711/1A (stainless steel). In contrary, the 5711R gives me different look due mainly to the rose gold case, fantastic dial and hands, and leather strap.
My bottom line is I prefer 5712/1A to 5711/1A but I feel very comfortable to pick the formal and dressy 5711R too.
Cheers
