Introduction
A new blue dial shading to black for the steel version
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 30 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.

A disc, decorated with golden stars and two golden moons against a blue or white background representing the sky, rotates within an aperture. The disc is cut from a wafer of corundum crystal (sapphire).
Gold was condensed onto the disc by means of a vacuum process through a photographic mask to create the shape of the moons and stars. The aperture is cut at its upper edge in order to represent the lunar cycle.
During the first days of each lunation, the leading edge of a golden moon becomes visible as a crescent on the left of the aperture and appears to wax as it emerges beyond the curved edge of the aperture representing the lunar terminator.
Half way through the lunation, the moon appears full. It then wanes as it disappears behind the terminator on the right of the aperture.
As the moon vanishes, the second moon on the disc is ready to appear on the left.

Savoir faire
In this exclusive interview, Thierry Stern talks openly of his affection for minute repeaters - his favorite of all the complications. From his earliest childhood memories through to his vision of future developments, he reaffirms the personal contribution that he insists on making with every minute repeater timepiece that is created by Patek Philippe - just as his father, his grandfather and his great-grandfather did.
