Patek Philippe Nautilus Annual Calendar Blue 5726

About this item

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.

This elegantly sporty exterior, water-resistant to 120 m, conceals a caliber 324 S QA LU 24H/303 self-winding movement comprising 347 parts, which can be admired through a sapphire crystal case back.
