ZF Manufacture Hublot Big Bang UNICO 441 Yellow Magic Ceramic Review:
First of all, we took a caliper to measure the thickness of the dimension, and after the actual measurement, the size was 42mm, and the thickness was 15.6mm. In terms of weight, it weighs 165 grams with the strap and 113 grams with the head alone.




In terms of overall appearance, the ZF Factory Hublot Big Bang UNICO Series 441 Yellow Magic Ceramic Watch is another ceramic replica that has impressed Bokey after the VS Deep Sea Black model. The watch is primarily crafted from polished yellow ceramic, which is highly challenging to process—requiring precise color matching while maintaining a smooth and delicate finish, no easy feat. Through real-life images, one can see that the ZF Factory UNICO Yellow Magic boasts excellent craftsmanship, with well-tuned color tones that exude a premium texture without appearing dull.

The ZF Big Bang UNICO Yellow Magic Ceramic watch features an anti-glare sapphire crystal and the HUBLOT logo is printed on the glass.


The entire dial features a highly hollow design, with the degree of hollowing maximally restored to the original. We can observe the structure of the movement and its operational effects when in motion. For example, the second wheel beneath the small seconds sub-dial at the 9 o’clock position operates identically to the genuine version, and gear movements are visible when adjusting the time and date. Compared to the Big Bang series models from other factories, ZF Factory excels in detail processing—the gears produced by other factories do not actually rotate.


At 3 o’clock, there is a 60-minute counter, which can only be timed for 30 minutes like the Big Bang series of the HB factory, while the ZF factory achieves the same 60-minute chronograph as the original product, which is also exclusive to ZF. In addition, the date window of the ZF Big Bang is also opened in the chronograph counter, and the previous products can only be opened at 4 o’clock due to the movement limitation, which causes the problem of false at a glance, while ZF factory will not.

The date dial font is matte and original.

The two black buttons on the lugs are also a quick-release design that synchronizes the original structure, and the rubber strap can be removed by simply pressing a button. The feel of the quick release is also very smooth, not as jerky as other factories do!



The case is also of the same structural design as the original, including the mounting method, which is also fixed by the upper and lower screws.

On the other side, the three pushers function from top to bottom, starting and pausing the chronograph, with a screw-down knob in the middle, which is also rubber-encased, and the third button is the chronograph reset button.


The movement is 7750 to change the deck of the 1280 movement, not the ZF factory to promote the self-produced R & D movement, in fact, this is ZF factory bragging, we generally do not look at the manufacturer’s copywriting, only look at the product itself. And the Hublot Big Bang is not a popular style, like the water ghost Daytona, which can make 3135 4130 self-produced integrated movements, after all, there is a large demand.

Like we often come into contact with watches, we can find that the position of his movement balance wheel can be found directly by looking at the position of his movement balance wheel in the ZF factory explosion, and the original is at 7 o’clock, so he is 7750 modification, HUB1280 the movement deck is still presentable, and it is not easy to see the real or false for ordinary people, and it will not be said that it is fake or anything, and it can only be found by comparing with the genuine. But for those who know how to do it, these flaws are easy to see, but relatively speaking, the probability of hitting the watch in real life is not large. After all, this is an authentic watch limited to 250 pieces.

After talking about the movement, let’s talk about some flaws in the back cover, the first aspect is that the process of the ceramic back cover is wrong, the genuine product is the microbead sandblasting process, in short, it is matte texture, which is the same as the back cover of the black magic, and the yellow magic of ZF is made into a polishing process. The second aspect is that the engraving on both sides of the case back is not filled with black oil, and Bokey believes that ZF should launch a V2 version to correct these two flaws in the future. As for the small problem of the screw flower on the bottom cover, this is purely caused by the carelessness of the assembly master, and Bokey will also carefully select the ones that do a good job in quality control before delivery, so cousins don’t have to worry too much.

It comes with a yellow and black structured rubber strap with a folding clasp in black ceramic and black titanium.




Summary: On the whole, ZF factory Hublot Big Bang UNICO series 441 yellow magic ceramic watch is still relatively good, if you think the original price of more than 190,000 is very expensive and you like it, then you can also start this ZF factory yellow magic to detoxify, the price of this small 4000 detoxification is also very good. In addition, ZF factory also launched a total of five colors for cousins to choose from, if you care too much about the flaws in the case back of the cousin can also choose other colors, black and white two colors are also recommended by Bokey, and the case back and the back lettering are also on the version.
