For years, the Patek Philippe Nautilus 5712/1A-001 was considered the “Everest of Complications” in the super clone industry. Replicating an asymmetric dial with a functional 48-hour power reserve indicator between 10 and 11 o’clock, a pointer date integrated with a lunar moonphase disc at 7 o’clock, and an off-center seconds register at 4 o’clock—all inside a slender 8.52mm porthole case—required developing a true 1:1 clone of Patek’s legendary Calibre 240 PS IRM C LU micro-rotor movement. Enter PPF V2/V3 and OME Factory.
- Real Off-Center 22k-Style Micro-Rotor (Calibre 240): Early 5712 replicas weighed 10.5mm thick and had a fake painted power reserve hand. PPF V2/V3 engineered the genuine-spec recessed micro-rotor movement, dropping case thickness to an astonishing 8.52mm.
- 100% Active Power Reserve Indicator: As you wind the crown or wear the watch on your wrist, the white pointer hand at 10:30 physically sweeps from the red emptiness dots up to the 48 full-wind mark, and gradually winds down as the mainspring discharges.
- Synchronized Moonphase & Pointer Date: Both the 31-day pointer ring and the metallic gold moonphase disc advance automatically at midnight (and can be quick-set via the recessed case-flank corrector pushers).
- Signature Blue-Grey Gradient Horizontal Embossed Dial: PPF’s dial transitions smoothly from smoky slate-blue at the center to deep charcoal at the outer minute track.
1. Dissecting the Calibre 240 PS IRM C LU Clone Movement
Why is a micro-rotor movement so prized by haute horlogerie collectors? In a standard automatic watch, the central oscillating weight sits on top of the bridges, adding 1.8mm to 2.5mm of height. On our Patek Philippe Nautilus 5712/1A 40mm Full-Function Micro-Rotor, the miniature winding rotor is recessed inside the same plane as the gear train bridges.
Through the sapphire crystal caseback, you have an unobstructed view of every bevelled bridge, the engraved Calatrava cross on the micro-rotor, the Gyromax-style balance wheel beating at 21,600 vph (3 Hz, matching the exact genuine Patek 240 beat rate!), and the Geneva stripe finishing.

2. Comparing 5712/1A vs 5726A Annual Calendar & 5711/1A
If you prefer a symmetrical dial layout while keeping the moonphase complication, inspect the Patek Philippe Nautilus 5726A Annual Calendar Moonphase Blue Dial, which arranges Day and Month windows at 12 o’clock above a 6 o’clock moonphase and 24-hour sub-dial. Or, for Gérald Genta’s pure three-hand icon, explore our Patek Philippe Nautilus 5711/1A Blue Dial and Patek Philippe Nautilus 5711/1A-014 Olive Green Dial.

Collector FAQ & Pre-Shipment QC Answers
Are there any hours when I should avoid using the moonphase/date corrector pushers on the 5712?
Yes—just like a genuine mechanical calendar watch, never press the case-flank date or moonphase corrector pushers when the watch hands read between 8:00 PM and 3:00 AM, as the internal calendar teeth are engaged for the midnight turnover. Always move the hands to 6:00 first before quick-setting the date or moonphase.
Does the power reserve hand move when I wind the crown?
Yes! Winding the crown in Position 0 visibly sweeps the power reserve pointer toward 48.
