The effect of the RED AR coating is amazing. I have tested it on a few different colours of dials, and for me the most obvious is that this RED reflecting AR coating is in fact a blue coating. So when you look through it, without reflections, you see blue! A white dial becomes light blue, white indexes and white lume becomes blue. The blue looks enhanced, especially when a darker dial is used the effect is very unusual. I have made some pictures and shorts to show the effect of this AR coating on different dial colours. All watches here have the 29mm double domed sapphire with red AR coating installed.
