The steel Nautilus now boasts a new blue dial with a gradual shading from blue to black at the edges, inspired by the original 1976 model. This refined aesthetic complements the sheen of the metal, while the horizontal embossing adds a touch of sportiness. The dial also features an Annual Calendar and moon-phase display, and the movement can be seen through the sapphire crystal case back.
