Patek Philippe Aquanaut 5167A-001 3K Factory Review: A Super Clone Worth Considering?

[...]

Introduction​

The Patek Philippe Aquanaut 5167A, often nicknamed the "Patek Hand Grenade" due to its textured dial resembling military-grade explosives, is one of the most sought-after luxury sports watches. With retail prices skyrocketing and waitlists extending for years, many enthusiasts turn to high-end replicas for a more accessible alternative. Among the top-tier replicas, the 3K Factory version has gained significant attention for its near-perfect replication of the genuine model.
In this review, we’ll examine the 3K Factory Aquanaut 5167A-001 in detail, comparing it to the genuine piece and assessing its strengths and weaknesses.

1. Case & Build Quality
The 3K Factory Aquanaut 5167A is crafted from 316L stainless steel, matching the original in weight (92g) and dimensions (40mm diameter, 8.1mm thickness). The case features:

• Brushed and polished surfaces (matching the gen)
• Accurate lugs and crown guards
• Properly engraved caseback (though some minor differences in font depth exist)

One of the most impressive aspects is the thickness—many replicas fail here, but 3K nailed it, making it nearly indistinguishable from the real deal at a glance.

2. Dial & Hands
The black embossed dial is a standout feature, with correctly sized and spaced numerals and a superb texture that mimics the genuine Aquanaut’s "grenade" pattern. Key improvements in the latest 3K version include:

• White Super-LumiNova (older versions had a greenish tint, now corrected)
• Improved printing quality (font thickness and alignment)
• Better lume application (strong and long-lasting, matching gen performance)

The hour and minute hands are well-shaped, though under high magnification, slight edge imperfections can be seen—hardly noticeable in real-world wear.


3. Movement: The 324 SC Clone
The biggest selling point of the 3K Aquanaut is its custom Cal.324 SC clone movement. Unlike other replicas that use modified Miyota 9015 or Seagull movements, 3K developed a true clone with:

• Correct thickness (3.3mm)
• Functional Geneva stripes and perlage decoration
• Similar power reserve (~35-40 hours)

However, there’s one major tell:

• The genuine 324 SC uses a free-sprung balance (Gyromax), while the 3K version still uses a regulated balance wheel with adjustment screws. This is the most noticeable difference when inspecting the movement closely.

Despite this, the movement is reliable and visually convincing for most wearers.

4. Bracelet & Clasp
The rubber strap is another highlight:

• Soft, flexible, and comfortable (very close to gen)
• Correct "Tropical" composite material
• Accurate buckle engraving

The newer 3K version offers an upgraded folding clasp, though some users report that the older version is still preferable for value.

5. Comparison with Other Factories (PPF, ZF, PF)
Before 3K, the PPF and ZF versions were the top choices, but they had flaws:

• Thicker cases (due to modified Miyota movements)
• Incorrect dial texture (less refined)
• Weaker lume application

3K’s improvements make it the current best option for an Aquanaut 5167A rep.

Final Verdict: Should You Buy the 3K Aquanaut?
Pros:

• Near-perfect case dimensions (thickness is spot-on)
• Excellent dial and lume (latest version fixes previous flaws)
• Best clone movement available (though not 100% identical)
• Great strap and clasp quality

Cons:

• Movement is not a true Gyromax (balance wheel difference)
• Minor dial imperfections under macro (but negligible in daily wear)

Conclusion
If you’re looking for the closest possible Aquanaut 5167A replica, the 3K Factory version is currently the best choice. While no rep is perfect, this one comes extremely close—enough to fool most enthusiasts at a glance.
