Description
3KF Edition Patek Philippe Nautilus 7118/1A-011 Gray Opaline
The integration of a true 1:1 clone movement allows this 3KF release to match the genuine 8.6mm thickness, setting it apart from standard Miyota-based alternatives.
Powered by Clone Caliber 324
The beating heart of this 7118 replica is the sophisticated Clone Caliber 324. Unlike lesser versions that glue decorative plates onto stock Japanese movements, 3KF engineered a 1:1 split architecture that mirrors the genuine Patek Philippe mechanism. This includes the correct positioning of the shock absorber, a functional gear train visible through the sapphire caseback, and a 21K gold-plated central rotor bearing the Calatrava cross. The movement is meticulously evaluated, ensuring each piece meets prior to dispatch. The latest iterations of this caliber also incorporate the hacking (stop-seconds) function and a smooth quick-set date mechanism, aligning with modern updates.
This 3KF clone caliber is typically regulated to operate within ±5–8 seconds per day, offering highly stable amplitude and reliable daily performance.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, sweep seconds, and centered date display at 6 o’clock
- ✅ 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
The case measures exactly 35.2mm from 10 to 4 o’clock, with a remarkably slim 8.6mm thickness. The brushed surfaces contrast sharply with high-polish chamfers along the octagonal bezel.
Features the 7118-specific undulating wave relief rather than the 5711’s straight horizontal bars. Includes a distinct black-gradient rim and white gold-textured applied markers.
The iconic porthole-inspired bezel is meticulously finished with a vertical satin-brushed top surface and flawless mirror-polished rounded edges.
Constructed with satin-finished outer links and highly polished center links. Secured by an upgraded fold-over clasp featuring the patented lockable micro-adjustment system.
Why 3KF for This Reference?
Many collectors ask: ‘Why not PPF?’
While PPF produces excellent Nautilus models, their reliance on modified Miyota 9015 movements inherently adds thickness to the case, disrupting the elegant proportions of the 35.2mm 7118. 3KF’s proprietary 1:1 clone movement not only eliminates rotor noise common to Miyota bases but also achieves the precise 8.6mm thickness of the genuine article, making it the superior structural choice.
Full Disclosure: While the date wheel font has been significantly improved and centered in this latest batch, under extreme macro magnification, the ink saturation can appear marginally thicker than the genuine piece.

Collector Q&A
Q: How does the thickness of the 3KF 7118 compare to the genuine piece?
A: The 3KF version measures exactly 8.6mm in thickness, which is 1:1 with the genuine Patek Philippe 7118. This is achieved by utilizing their proprietary clone movement rather than a thicker modified Miyota caliber.
Q: Is the dial color accurate to the genuine Gray Opaline?
A: Yes, 3KF has successfully replicated the distinctive Gray Opaline wave pattern, including the subtle black-gradient rim (smoke effect) that darkens toward the edges of the dial, along with the correct sunburst light play.
Q: Does the clasp feature the micro-adjustment system?
A: Yes, this 3KF edition replicates the lockable adjustment system found on the modern Nautilus fold-over clasp, allowing for up to 2-4mm of sizing changes to accommodate wrist expansion during warmer weather.
Q: Are there any known quirks with the 3KF Caliber 324 clone movement?
A: While visually accurate and structurally thin, the 3KF clone movement’s rotor can occasionally be slightly more audible than the genuine piece during vigorous wrist movement. Additionally, date wheel alignment at the 6 o’clock window requires careful QC to ensure perfect centering.
