PATEK PHILIPPE NAUTILUS ANNUAL CALENDAR BLUE DIAL 5726/1A-014
The steel Nautilus, endowed with an Annual Calendar and moon-phase display, now features a new blue dial inspired from the dial color of the original Nautilus model of 1976. Horizontal embossing and subtle grading from blue to black at the dial’s periphery create a powerful yet refined aesthetic that perfectly complements the sheen of the metal.
