Hello everyone, this is Bokey. As a classic watch series of IWC, the Portuguese series is loved by many watch enthusiasts with the Portuguese chronograph (Portuguese series chronograph watch) and Portuguese seven-day chain watch. The Portuguese chronograph with high appearance and thinner thickness is especially so. The simple and exquisite dial design presents a full sense of quality on the wrist. A previous authenticity evaluation of the ZF factory V2 version of the Portuguese chronograph with blue nails and white face compared to the genuine product has been done. Interested friends can look it up in the “Authenticity Comparison” column on the website. So in this watch evaluation, let’s simply talk about the ZF factory V2 version of the Portuguese chronograph with a black face and see how the specific workmanship details are? Are there any shortcomings? In addition, currently the ZF factory only has the V2 ultimate version of the Portuguese chronograph. There is no V3 version. The V3 version is just something that merchants do to attract traffic!

First, let’s take a look at the genuine product parameters: IWC Portuguese series IW371447 watch, price 58700.


In terms of the front appearance, the black dial is matched with silver sword-shaped hands, clean and neat. The two small dials are just right and embellish it. The dial details of the ZF are replicated one-to-one and impeccable.

The watch mirror uses double-sided anti-reflective convex sapphire glass and is coated with a blue film. We can see that the blue coating under light is very textured and can achieve a color and transparency comparable to the genuine product.

The digital scales on the dial are also very round. Unlike the previous old version where the numbers are cut off with one stroke, there is no arc at all on the edges of the numbers. The chronograph hand and minute hand are both slightly curved downward and stretched along the edge of the mirror. This is also in line with the original.


The two threaded ring patterns of the chronograph dial are more delicate than the old version. That is, the large ring of the same size contains more threads as a whole, and the dial looks very textured.


From the side view, the stainless steel crown is also polished. The IWC logo pattern is engraved on it, and it is designed with anti-slip texture, which is comfortable to hold and convenient and fast to adjust and operate. The upper and lower parts are respectively the chronograph start/pause and chronograph reset buttons. The operation feeling is full, showing the connotation of the exciting mechanical representative function of chronograph.


Looking at the back cover again, this part is a process of alternating brushed and polished finishes, which is more complicated. It can be seen that each grain of the brushed finish is very fine, and then the polished part is very bright. At the same time, the font on the back cover is deep and powerful, and the three-dimensionality is also enhanced.

Regarding the movement, the original uses the CAL.79350 movement. However, the ZF factory uses the Dandong 7750 movement as the basis, removes some splints and parts, and modifies it into the Cal.79350 movement, making the entire watch thinner and achieving consistency with the original. At the same time, due to the greatly reduced number of grafted gears in the movement, it is more stable than previous movement versions.


The ZF factory uses calfskin material. The overall feel is relatively poor and hard. It is recommended to upgrade to crocodile leather later by looking for Bokey. In terms of the buckle, it also uses the most classic push buckle of IWC. The overall polishing of the buckle is very in place. The size and depth of the classic IWC engraving on the buckle are also in line with the original. The inside of the buckle is also engraved with the IWC font. The size and thickness of the embossed engraving are all consistent with the original.

Summary: Through the above detailed evaluation, we can see that the IWC Portuguese chronograph series watches from the ZF factory have reached the degree of being indistinguishable from the genuine product in terms of the entire appearance and dial. Coupled with the closed back design, the entire watch looks flawless and is very good. Therefore, in the case of so many choices in the replica market, only the ZF factory is relatively perfect.
