Description
3K Factory Patek Philippe Nautilus 7118/1200A-011
A dimensional triumph achieving the genuine 8.4mm profile via a true clone movement architecture.
Powered by Clone Caliber 324 SC
The engineering core of the 3KF 7118 is its Clone Caliber 324 SC. Moving away from the noisy, thick decorative plates found on Miyota 9015-based replicas, this caliber is built from the ground up to mimic Patek Philippe’s layout. It incorporates visual cues such as a simulated Gyromax balance wheel and meticulously applied perlage côtes de Genève finishing across the bridges. The unidirectional winding rotor operates with smoother acoustics than its Japanese counterparts.
The 3KF Clone 324 SC is typically regulated from the factory to operate within ±5–8 seconds per day, offering reliable daily performance for a specialized clone movement.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, sweep seconds, and date in aperture
- ✅ Winding Direction: Unidirectional (counter-clockwise)
Technical Notice: Clone 324 Movement
The replica market currently produces only the Clone 324 movement. Even if movement bridges are engraved “330”, the mechanism operates as Clone 324.
Practical implication: The seconds hand does not stop when setting the time. This is correct behavior for this movement and ensures maximum long-term stability.
Technical Specifications
Measuring exactly 35.2mm in diameter with a verified 8.4mm thickness. The case exhibits sharp transitions between the satin-brushed bezel flanks and the high-polish chamfers.
Features undulating horizontal lines specific to the ladies’ Nautilus line. The gray opaline tone is achieved with correct lacquer thickness, complemented by applied gold hour markers.
The iconic porthole bezel is set with synthetic stones (CZ) to replicate the 56 diamonds of the genuine 7118/1200A, secured via precise mechanical setting rather than adhesive.
Features the updated Nautilus fold-over clasp. The central links are mirror-polished, contrasting sharply against the brushed outer links with tight endplay tolerances.
Why 3KF for This Reference?
Many collectors ask: “Why not PPF?”
While PPF produces exceptional Nautilus dials, their reliance on a modified Miyota 9015 movement forces their case thickness to exceed 9.0mm. 3KF’s proprietary clone movement is the only mechanism allowing this replica to achieve the verified 8.4mm thickness and 106.7g weight, making it the superior choice for tactile accuracy.
Full Disclosure: The synthetic stones used in the bezel setting lack the VVS clarity and refractive fire of genuine Patek Philippe factory diamonds, and the gray dial tone can appear slightly cooler under direct sunlight.

Collector Q&A
Q: Is the 8.4mm case thickness accurate to the genuine 7118/1200A?
A: Yes. Because 3KF utilizes a true clone 324 caliber rather than a decorated Miyota base, it successfully achieves the precise 8.4mm profile of the authentic piece, avoiding the thicker case found on rival factory versions.
Q: Are the stones on the bezel real diamonds?
A: No. The factory uses high-quality cubic zirconia (CZ) to replicate the 56 diamonds found on the genuine bezel. They are mechanically set, not glued, but lack the refractive index of real diamonds.
Q: Does the seconds hand hack (stop) when setting the time?
A: No. Consistent with the genuine Patek Philippe Caliber 324 SC, the seconds hand continues to sweep while setting the time. This non-hacking feature is correct behavior for this movement architecture.
Q: How does the 3KF gray dial compare to the PPF version?
A: While PPF is historically praised for its base dial colors, 3KF offers superior correct lacquer thickness. However, collectors note that the 3KF gray opaline tone may appear slightly cooler under direct sunlight compared to the genuine article.
