In what ways has the 330 movement in the 3K Factory Patek Philippe Hand Grenade 5167 V3 version been improved compared to the old model?

Patek Philippe Aquanaut 5167 model is produced by 3K Factory with a solid stainless steel case, 40 mm diameter and high-precision automatic Super Clone movement architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.

Currently, the shipment of Patek Philippe Hand Grenade produced by 3K Factory is the newest version. Actually, there is no exact distinction of "which version", but let's call it the V3 version out of habit. First of all, let me say it for 3K Factory; This factory is one of the manufacturers that transformed by adopting the Nautilus model. After successfully molding models such as Nautilus, it later evolved into BT Factory Rolex and similar models. Of course, pay attention to this here: 3K Factory and BT Factory are the same place, only the products they handle are different. As for the 3K Factory development this time: the automatic rotor has been renewed, Swiss-made ultra-precision bearings have been used, and rotor assembly workmanship has been applied that has never been seen before in the industry. At the same time, improvements have been made on the movement side: no fake bridge, no fake balance wheel, no fake ruby. 3K Factory has produced an exact replica of the discontinued high-quality 3.3 mm 330SC movement. Note here: the 330 movement was actually designed in 2022; However, it is the Nautilus and Hand Grenade models that have recently increased the popularity of the 330 movement. So how does the 3K Factory produced Patek Philippe Grenade 5167 “V3 version” compare to the original? Can you tell it's fake at a glance?

In fact, 3K Factory was not the first to make the mold for the Hand Grenade model; In addition, serious improvements have been made to this model. 3K Factory also shared a very clear official statement regarding the points developed; Let's briefly comment below together! Improvements were made mainly on the mechanism and appearance. 3K Factory developed the 330 one-piece movement; All engravings are finely processed, look clear, not corroded, and the texture is maximized. This point also creates a certain difference in terms of appearance compared to the previous version! As a one-piece mechanism, this is also an improved version of the automatic rotor; Swiss-made ultra-precision bearings and rotor assembly workmanship never seen before in the industry are used. 100 percent silence was achieved; There is no excessive sound sensation, and it is extremely comfortable when you wear it! Moreover, this 3K production remains true to the original movement: no fake bridge, no fake balance wheel, no fake ruby!

The dimensions given by the factory for the Patek Philippe Hand Grenade produced by 3K Factory are 40 mm in diameter and 8.1 mm in thickness. Patek Philippe's iconic octagonal design is realistically reproduced; It is a perfect replica, both in terms of dimensions and overall appearance. Watch glass sapphire crystal; The glass has a double-layer anti-reflective coating, its transparency is completely high, and the grenade pattern on the dial is clearly visible. Then, the bezel was sealed tightly with stainless steel, further strengthening the water resistance; The bezel has undergone vertical brushing work. 3K Factory has produced a perfect replica of the original's embossed checkered pattern; This pattern perfectly complements the Arabic numeral hour markers, minute markers, and baton-shaped hour and minute hands. The hour markers and hour and minute hands are coated with a lume layer. In the brand logo below 12 o'clock, 3K factory used the same high-precision scanning and ink filling technique as the original; This gives the brand logo more three-dimensionality and highlights the quality symbol of the brand!

Glass and Sapphire Crystal

Sapphire glass is the indispensable material of a watch; It both increases the transparency of the watch and prevents scratches from appearing on the watch easily. As for the dial design, the overall texture of the watch is quite strong. Arabic numeral hour markers are engraved with soft lines; The length and spacing of the five-minute marks are also fine. The lume is properly filled in the baton-shaped hour and minute hands, the three-dimensionality of the logo print is consistent and the font is smooth! The handling of details is extremely appropriate; The dial font is also very clear! There is also lume detail on the dial markings. 3K Factory is really successful when it comes to mastering the details! (In the case of the stainless steel Grenade!)

The crown is beautifully crafted; Water resistance performance is quite good with its screw-down crown design. After all, this is a dedicated dive watch. The logo engraved on the top of the crown is three-dimensional and vivid.

The thickness and shape are the same as the original. The ears on both sides are extremely symmetrical; This shows that the 3K factory made its mold very perfectly.

The thickness from the side is the same as the original, i.e. 8.1 mm. The side surface is processed with matte finish; The original version has a fox pattern on the upper side surface and fits very well on the wrist.

Case and Body Workmanship

There is a screw-down glass case back design on the back; Thanks to this glass, you can directly watch the beauty of the mechanism. The movement of the watch has been upgraded to caliber 330 and the stability of this movement is really successful. Please note here: This does not mean that the replica watch has no flaws. While the original used a non-adjustable (free) balance wheel, the replica still uses an ordinary adjustable balance wheel; so there is still a difference in appearance. The original's balance wheel is a weighted balance wheel, while the replica's is a flat prototype. In short, one differs in the weight of the balance wheel, the other in the smoothness of the balance wheel. I can say that the replica tries to imitate the original to the extreme; after all, its price is not even a fraction of the original!

Strap, Buckle and Comfort

The workmanship on the strap side of this watch is also quite good. This time, the Grenade uses a rubber belt, and the workmanship of the Grenade's rubber belt is quite different; It provides a stable and comfortable stance when installed with a unique locking mechanism. Such details are a ceiling level that other factories cannot reach. The processing of the strap details is also quite appropriate. Please note here: the straps are quite long, so you will have to shorten them yourself when you receive the watch; The detail in the original is also like this. I also recommend shortening it a little too much! Additionally, the Patek Philippe logo was developed on the watch's buckle; so the clock icon can overlap perfectly. The factory's workmanship is very good when it comes to details!

Summary: 3K Factory has reproduced the Patek Philippe Hand Grenade 5167 extremely flawlessly. It imitated the original to the extreme in terms of both external appearance and mechanism details; In terms of texture, it is infinitely close to the original version. It is currently the highest version in the high-end replica watch market. This time, the V3 version 330 movement update is a synchronous adjustment with the official website. This is a model that watch enthusiasts who love watches can buy and use with peace of mind.
