Patek Philippe Nautilus Annual Calendar Moon Phases Stainless Steel Black Dial | 5726A-001

Powered by Patek Philippe's automatic calibre movement, this Nautilus 5726A-001 delivers the annual calendar complication with moon phases through a 40.5mm stainless steel case paired with a distinctive black dial. The sophisticated mechanical architecture manages the calendar display with minimal manual adjustment, requiring correction only once per year at the end of February. Behind the transparent case back, collectors witness the intricate engineering that drives both the time display and astronomical indications, while the screw-down crown ensures 120-meter water resistance despite the complex movement within.
