This Patek Philippe Nautilus 5712/1A-001 super clone delivers a 40mm stainless steel case with a charcoal-black dial carrying three subdials: power reserve, date with moon phase, and small seconds. Where the 5711 keeps the dial minimal, the 5712 fills the same 40mm case with practical complications that add daily functionality. Patek Philippe fitted this reference with the ultra-thin caliber 240 PS IRM C LU, one of the slimmest automatic movements capable of driving a moon phase display alongside a power reserve indicator and pointer date. Our watch reproduces those displays with the clone Cal. 240 PS IRM C LU, and the 5712 moon phase and power reserve chapter of our guide shows how they are read.

The moon phase sits inside the date subdial near seven o’clock, a disc with two painted moons that cycle through the full 29.5-day lunar period. The power reserve arc near ten o’clock shows remaining energy in the mainspring.

Micro-Rotor Thinking Behind the 5712

Patek’s own caliber inside the genuine 5712 uses a micro-rotor design instead of a full-size rotor, which allows the movement to remain thin enough for the Nautilus case profile. This design choice separates the 5712 from most complication watches that sacrifice case thickness for functionality. The black dial grounds the three subdials visually, preventing the face from feeling cluttered despite the additional displays.

For a radically different Nautilus format, see the 7118/1200R-010 ladies model with its golden brown dial.

Moon, Reserve and Date on One Steel Dial

The 5712 answers a specific question: what happens when you add real complications to the Nautilus without changing the case size. The answer is a watch that wears identically to the 5711 on the wrist but delivers moon phase tracking, power reserve monitoring, and pointer date in one glance. Black on stainless steel keeps the aesthetic grounded. This Patek Philippe Nautilus 5712/1A-001 replica sits between the simplicity of the 5711 and the annual calendar of the 5726.
