The steel bezel sets a cool border around the bright face. With a white face, the choice is about legibility and contrast rather than color depth; it suits a rotation that already contains darker sports watches.
The annual-calendar windows occupy the upper dial, with the moon phase below; a white background gives each element room to separate. The steel bezel provides the familiar Nautilus boundary, so the watch still reads as a sports case rather than a plain white dress watch. Grey is the darker alternative when the indications should blend more softly. This white version is the clearer choice for a collection already rich in dark faces, because the dial itself changes the wrist impression while the case architecture remains recognizable. The brighter field makes the moon-phase aperture especially easy to locate.
