Genuine vs. Fake Comparison: ZF Factory Portugieser Seven-Day Chain V4 Version vs. Authentic Model

Hello everyone, I am Bokey. In this watch review, I will bring you the comparison between the IWC Portuguese 7-Day Chain (Portuguese Seven) and the ZF factory V4/V5 versions of Portuguese Seven to distinguish the authenticity. Now, let’s talk about the differences and flaws between the genuine and fake Portuguese Seven through pictures and texts.

First, let’s take a look at the genuine product information and price.

IWC Portuguese Series IW500705 watch (new Portuguese Seven), dial diameter 42.3mm, official price 93,600.

1.Front comparison: The left is the genuine product, and the right is the ZF factory V4/V5 version of Portuguese Seven. Both dials use blue Arabic numeral scales and an orbital minute scale circle, exuding an elegant temperament. Upon careful observation, the watch glass of the genuine product is relatively transparent, while the reflective effect of the filter film of the ZF version of Portuguese Seven is even better.

2.Pointer comparison: The pointers are treated with blued steel. The ZF Portuguese Seven is very accurate in color control. The blue slender willow-leaf-shaped pointers are exactly the same as the genuine product. Although there are slight differences in the central axis, they are difficult to distinguish with the naked eye.

 

3.Subdials & Power Reserve: The left small seconds subdial with a railway-track minute scale and the right power reserve indicator are highly accurate reproductions. The dial craftsmanship is exceptional, particularly the precise two-color (red/black) printing on the power reserve display – no overlapping or color bleeding occurs

4.LOGO comparison: The IWC font on the ZF Portuguese Seven is basically the same as the genuine product. The SCHAFFHAUSEN font below is slightly thinner than the genuine product, and the color is also lighter than the genuine product. Therefore, the genuine product appears to have stronger three-dimensionality.

5.Calendar comparison: The ZF factory V5 Portuguese Seven has the same calendar window as the genuine product. The replica also has the same arc treatment as the genuine product. The printing is exactly the same. Through magnification, we can see that there is also a little burr on the number 1 of the genuine product. Of course, this is also a flaw of the genuine product that can only be found after magnification. Many watch enthusiasts may think that the genuine product is perfect, but in fact, it is not. Watches are industrial products and cannot be flawless. Just treat it rationally. It is worth mentioning that regarding quality control issues, the calendar of the ZF factory V5 version of Portuguese Seven may sometimes be off-center to the left. This is a quality control issue. Finding the right merchant can solve this problem. It is best to confirm with pictures before shipping to avoid the trouble of back-and-forth returns.

6.Mirror comparison: Whether it is the font ratio, reflective color or the blue coating of sapphire, the two are like coming from the same production line. There is really no difference. Looking from another angle, both use a relatively transparent sapphire mirror and are coated with a blue film for anti-glare treatment, which is very transparent.

7.Side comparison: The thickness of the ZF Portuguese Seven is the same as that of the genuine product. Great efforts have been made in the brushed treatment of the case. The brushed treatment of the case is almost perfect.

8.Crown comparison: The size of the crown is the same, and the thread treatment of the crown is also in place. The IWC pattern on the crown is exactly the same. But upon careful comparison, the outline of the ZF factory v5 version of Portuguese Seven is slightly thinner than that of the genuine product.

9.Back comparison: The ZF V5 version of Portuguese Seven uses the Dandong machine to imitate the genuine Cal.52010 movement. After a long period of correction and adjustment, the internal structure and thickness of the ZF movement are almost the same as the genuine product. The entire movement plate is very delicate after being polished with fish scale patterns and Geneva waves. There are also ruby embellishments and gold-plated lettering on the plate. It can be said to be a remarkable innovation in the replica watch industry. It has completely realized the functions of the left and right eyes and also achieved a perfect fit in position. The only deficiency is that the gears cannot move. But in terms of the appearance of the movement, it has reached about 90% of the authenticity.

10.The overall appearance of the movement back is no different. When shaking carefully, you will find that the genuine product will make a slight “dada” sound when shaking the automatic hammer, giving the feeling of high winding efficiency. The replica version has corrected the noise of the automatic hammer and only makes a slight “swish” sound.

11.Looking from another angle, the gem positions of both are in perfect proportion. The replica polishing treatment is the same as the genuine product, and the movement plate is very delicate after being polished. The only difference is that when manually winding, the gears of the genuine product can operate. However, the plate is only for decorative purposes and does not affect the actual use effect.

12.Ruby embellishments and gold-plated lettering on the plate. The replica is a remarkable innovation for the genuine product. It has completely realized the functions of the left and right eyes and also achieved a perfect fit in position.

 

13.Back cover comparison: The back cover is completely configured according to the genuine product. There are grooves provided at the bezel for disassembly. A screw-in sapphire glass back cover is used, and the engraved numbers are not repeated.

14.Buckle comparison: The ZF factory Portuguese Seven has also spent a lot on the buckle. Whether it is the appearance design, brushed detail creation, corner polishing or structural restoration, it is all very perfect. The same process as the genuine product is used, making it excellent and flawless. It can be used interchangeably with the genuine product. The inside treatment when opening the buckle is also very delicate, and the detail processing is in place.

15.Looking at the buckle LOGO enlarged, the font depth and polishing process are all very perfect.

Summary: The above is the authenticity discrimination comparison between the ZF factory v5 Portuguese Seven and the genuine product.
