Patek Philippe Nautilus Moon Phases, Ref. 5712/1A - Black-blue Dial

The Patek Philippe Nautilus, Moon Phases Reference 5712/1A, stands as a highly sought-after horological masterpiece, embodying Patek Philippe's blend of iconic design and intricate mechanical complications. This specific model, released in 2025 and offered in Brand New, immaculate condition, represents a premier investment piece within the luxury watch market.

Crafted from Stainless Steel, the 5712/1A maintains the distinctive Nautilus aesthetic conceived by Gérald Genta, characterized by its porthole-inspired case measuring approximately 40mm (width including crown guard) x 38mm (diameter at 10-4 o'clock) with a slim profile of 8.52mm. The integrated bracelet and the signature horizontally embossed blue-black dial with applied luminous hour markers define its unmistakable visual identity. The transparent sapphire-crystal case back offers a view into the sophisticated movement.

At its heart lies the ultra-thin self-winding Calibre 240 PS IRM C LU, a testament to Patek Philippe's engineering prowess. This movement integrates multiple complications seamlessly into the classic Nautilus case. Key features of this advanced calibre include:

• Moon Phases display, precisely tracking lunar cycles.
• Analog Date indicated by a subsidiary dial at 7 o'clock.
• Power Reserve Indicator, prominently displayed between 10 and 11 o'clock, showing the remaining energy of the movement.
• Small Seconds sub-dial at 4 o'clock.

The Calibre 240 PS IRM C LU operates at a frequency of 21,600 semi-oscillations per hour (3 Hz) and boasts a power reserve of approximately 38 to 48 hours, highlighting its practical functionality alongside its aesthetic appeal. Its historical significance stems from integrating complex astronomical indications within the robust framework of the Nautilus sports watch, a combination that has cemented its status as a true collector's item and a significant technical achievement for the brand.

As a 2025 release in Brand New condition, this Patek Philippe Nautilus 5712/1A offers an exclusive opportunity to acquire a highly coveted reference directly from its production year. Its combination of iconic design, material, and sophisticated complications ensures its position as an exceptional investment piece and a cornerstone for any serious horological collection.
