My impression is that while the blue is still preferred by a majority more and more people are starting to appreciate the white.
For me both are superb. The blue (which is really more gray than blue at least in recent production) looks pretty spectacular in day light or in a well lit room. At night or in a dimly lit room the dial appears dark gray and for me that is not nearly as pleasing as the icy cool white, which looks great anytime / anywhere. Which do I prefer overall - not sure anymore. Very close choice.
FYI - Yesterday in Geneva a white Tiffany 5711 1/A was sold at auction. At least 2 people, one of which was the winning bidder has a great appreciation for the white. Of course, the "Tiffany" obviously was a factor, but nevertheless ... Best, Patekova
