Disagree somewhat
in regard to the blue vs black dial.
One of the dial characteristics that we hold dear about the Nautilus series is the "striated" texture of the dial. Black dials with this texture are stunning. I think these can be seen on the 3711, 5711G, and new version of 5980. Maybe also adds a touch of elegance, if taking away a touch of sport. Just as beautiful and classic as the blue dials IMHO, though the blue is more in line with the original 3700.
The black dial on the 3710 is a different beast IMHO. Flat black dial is just not the same, and that watch has romans to boot (rather than stick markers), so not a great reference to use to compare Nautilus black to blue. But definitely a cool watch with the unique comet PR indicator.
