Not all blue dials are equal or even similar. Look at the difference from the somewhat sunburst blue dial of the SkyD with the more gradient blue/grey dial of the 5712/1A.
The difficulty of comparing watches is to have them side by side and in similar lighting to be able to see the nuances as photos could be touched up, lack of color balance, white balance, saturation, etc...
Honestly, out of these 2, I prefer the SkyD blue dial in color. What do you guys think?
