On the track of replicating the Patek Philippe Aquanaut 5167A “Black Grenade”, BBF Factory was once regarded as the new favorite of high-end players with its continuous polishing of the surface texture and movement structure. However, when this model is equipped withIntegrated 324 movementwithSW replacement diskAfter testing the new version of 5167A, we found that it not only has surprising highlight details, but also has a flaw that is enough to dissuade some friends.
Disk texture: Close to the original radial pattern, better than 3K
First of all, what deserves recognition is that BBF is hereDisk technologyAttentiveness. Different from the early version of 3K factory that was gray and lacked layering, the SW replacement disk used by BBF this time successfully restored the iconic original version.Silver gray radial pattern——Not a simple gradient, but a three-dimensional texture with a delicate flow of light and shadow. Under natural light, it is almost difficult to distinguish the difference from the original; only when illuminated by strong side light, the reflection area is slightly smaller, but it is already at the top level among current replicas.
The calendar window is also highlighted. BBF made a separate mold for 5167A to customize the calendar font. The font thickness, height, and three-dimensionality are all highly aligned, far exceeding the “flat feel” of the 3K factory general template. If paired with professional modification parts such as Cousin, the visual consistency will be almost impeccable.
Movement performance: Bonus points for genuine engraved plywood, but it’s still “fake at first glance”
In terms of movement, BBF is equipped with self-developedIntegrated 324 movement, plywood adoptsLaser real engraving(Non-printing), the craftsmanship is better than 3K printing plywood. Although the automatic rotor is gilded, it is slightly grainy and the polishing fineness is slightly inferior. But we must be honest: whether it is BBF or 3K, the current integrated 324 movement is still “fake at first glance” in the eyes of experienced players——Balance wheel position, caliper structure, shock absorber layoutThere are still obvious differences between the key details and the genuine 324 or the top “Super 324”. If you pursue the ultimate simulation, you still need to consider higher-order solutions.
Fatal shortcoming: The head is too large and protruding, destroying the overall proportion
However, the most regrettable problem arises inCrown (handle) designon. The handle of BBF version 5167A is not onlyToo big, what’s more serious isThe length is too long and obviously protrudes beyond the case shoulder guard.. Comparing the actual photos of the original product, we can see that the center line of the original handle is completely embedded in the shoulder pads, and the lines are smooth and compact. The BBF version appears abrupt and bulky, seriously damaging the iconic sporty, elegant balance of the Aquanaut series. Of course, comparison is imitation, and it may not be 100% accurate.
Quality control concerns: calendar shift requires picking goods
In addition, BBF’s recent quality control stability is also worrying. Partial batches appearCalendar font installation offsetProblem – Although the font itself is correct, the position is not centered, which affects the look and feel. This is most likely due to insufficient calibration of the replacement calendar module during mass assembly. It is recommended to make sure that the seller provides strict quality inspection before buying to avoid being deceived. (For example, if you choose purewatches, you will strictly control the quality)
Summary: Who is it suitable for? Not suitable for whom?
- recommended to: Advanced players who pay attention to the texture of the board, can accept minor head defects, and are willing to optimize through later fine-tuning.
- Not recommended to: Users who pursue 100% appearance matching, value the coordination of overall proportions, or have limited budget and are unwilling to make secondary modifications.
The 5167A black grenade from BBF Factory is an attempt to “drive high and go low” – it achieves the ultimate in the most easily visible disk surface, but stumbles on the structural details that should be least likely to go wrong. For such a work with “extremely distinct advantages and disadvantages”, are you willing to tolerate its imperfections for its beauty?
