Hello everyone, this is Bokey. Today, we will answer a question that watch enthusiasts are concerned about: “Is the ZF factory’s IWC Portuguese 7-Day Chain in V5 or V6 version?” and questions about quality and workmanship. Let’s briefly talk about the upgrade points and details of the ZF factory’s Portuguese Seven V5 version.

Is the latest version of ZF factory’s IWC Portuguese Seven V5 or V6?
After multiple revisions of the ZF IWC Portuguese 7-Day Chain, various versions keep emerging on the internet, confusing many watch enthusiasts. Which version of the IWC Portuguese Seven is the best? Which is the latest version of the most famous ZF factory? In fact, it has been four or five years since the ZF factory initially produced the IWC Portuguese Seven. Since the beginning of 2018, the factory made the last upgrade and there has been no further upgrade since then. That is to say, V5 is currently the latest version and also the final version. According to the factory’s definition, it is an upgrade based on the V4 version and the lettering has been corrected. In the original V4 version, there would be problems of yellowing lettering and paint peeling off the digital scales. After the upgrade, the lettering color is consistent with the genuine product, and paint peeling off the scales is also avoided. The side of the lettering nail is silver when observed under reflection, which is consistent with the genuine product.


The second is the movement. The gem color on the movement of the V4 version is light purple. After correction, it is a bright pigeon blood color. It is even brighter. Compared with the genuine product, there is no color difference. The entire movement plate is more delicately polished with engraved patterns. There are fish scale patterns and Geneva wave patterns. There are also ruby embellishments and gold-plated lettering on the plate.

So, according to the actual situation of the factory, currently the latest version of ZF factory’s IWC Portuguese Seven is V5. Why are there various V6 versions called on the internet? It is because some merchants exaggerate for marketing purposes and mislead consumers to ultimately achieve the purpose of sales.
So what about the quality of the latest V5 version of ZF factory’s IWC Portuguese Seven? Is it worth buying?
The ZF Portuguese Seven is made of stainless steel, creating a watch diameter of 42mm and a thickness of 14mm. The wearing effect is simply perfect. The 316L stainless steel appears particularly noble after polishing and brushing processes, with a high gloss. The white dial is decorated with satin patterns and there is no reflection on the dial. In the middle are the hour and minute hands. The pointers are polished smoothly and full. The pointers are completely consistent with the genuine product. There is more or less a slight difference at the central axis, but it is difficult to distinguish with the naked eye.

The “IWC” lettering on the dial is basically the same as the genuine product. The “SCHAFFHAUSEN” font is slightly thinner than the genuine product, and the color is also lighter than the genuine product. The digital scales on the dial adopt an embedded three-dimensional structure. Before the V5 version, the scale numbers were all blue. Now after the upgrade, the side is silver, which is consistent with the genuine product. The ZF factory is still very pursuit of perfect details.


The two small dials on the left and right are exquisitely made. The one on the right is the power reserve display, which can indicate a week. The small dial on the left is the second hand. The CD patterns inside the small dial are very delicately polished, and the scales are also very clear.


The mirror surface uses sapphire crystal and blue coating, appearing very bold and wild, like a restrained man. It looks very beautiful in the sunlight, with extremely strong transparency and extremely close to the genuine product.

The side of the case uses horizontal brushing, and the brushing is very delicate. Once there is a slight scratch in daily use, the brushing pattern can well cover it up. The push-pull crown design has a classic large “IWC” logo engraved on the top of the crown, with high recognition and full of classic beauty.


The back cover uses a screw-in sapphire crystal back and a transparent sapphire crystal case back. The lettering is very clear and neat. One watch has one code and does not repeat. The numbers do not repeat. The ZF factory’s Portuguese Seven uses the Dandong imitation of the genuine Cal.52010 movement. After a long time of correction and adjustment, the internal structure and thickness of the V5 version movement are almost the same as the genuine product. The entire movement plate is very delicately polished with engraved patterns. There are fish scale patterns and Geneva wave patterns. It can be said to be a remarkable innovation in the replica watch industry.


The strap matched by the ZF factory at the factory is made of cowhide material with imitation crocodile skin patterns. The texture is a bit harder. The production of the butterfly clasp is also unambiguous and consistent with the original. The side brushing and polishing process is very delicate, and the detail processing is very in place.


Summary: After reading the above introduction, I believe you have a basic understanding of the ZF factory’s IWC Portuguese Seven. We cannot exaggerate and say that it has reached a perfect state. However, as a replica watch, its appearance, workmanship, and movement quality have brought us surprises. Although the latest V5 version of the ZF factory’s IWC Portuguese Seven cannot be completely indistinguishable from the genuine product, it can completely allow friends who are not rich to buy a worthwhile experience at a price that is one several dozen times lower than the genuine product.
