Contrast gives the dial its shape
The important visual choice is not simply blue; it is blue interrupted by silver. The lighter counters separate the chronograph display from the dial field and make the face easier to scan at a glance. Around it, the octagonal bezel and visible screw layout supply the hard geometry expected from a Royal Oak. The result is more graphic than the silver-and-blue 38mm configuration, because the larger case gives each contrast point additional room.
