Hello everyone, this is Bokey. This issue of evaluation and comparison brings you the authenticity evaluation of the ZF factory v2 ultimate version of the Portuguese chronograph compared with the genuine product. The IWC Portuguese series can be said to be the brightest star among the IWC brands. Among them, the Portuguese chronograph is favored by many watch fans for its high cost performance. The Portuguese chronograph has been replicated by many watch dealers. Due to the problem of repair rate, it was frequently suspended. At present, the best versions circulating in the market are the ZF factory and the YL factory. After numerous changes and revisions, the biggest change is that the original thick 7750 has been improved to replicate the genuine Cal.79350 movement, and the thickness is reduced by 1.4mm to be consistent with the genuine product! This authenticity comparison takes the genuine product and the ZF factory V2 version with blue hands and a white face. It is also the most beautiful one in the Portuguese chronograph series. Now let’s enter the authenticity comparison evaluation of the ZF factory V2 ultimate version of the Portuguese chronograph and the genuine product to see what flaws are there compared with the genuine product? Has the flaw of being obviously fake at a glance in the previous version been repaired?

First look at the official parameters: IWC Portuguese series IW371446 watch (Portuguese chronograph with blue hands), price 57000.


Overall appearance: The dial size ratio is the same as that of the genuine product. After careful observation, it can be found that due to the thinner movement, the height of the inner circle of the dial is consistent with that of the genuine product. This is unattainable by all previous versions and can also be used as one of the bases to distinguish the ZF factory v2 version of the ultra-thin Portuguese chronograph from other manufacturers’ versions.

Observing from another angle, we can find that after improvement and upgrading, the ZF factory V2 version of the Portuguese chronograph uses the genuine replicated movement Cal.79350, so there is more suitable space to set the inner circle, and it is highly consistent with the thickness of the inner circle of the genuine product. The inner circle scale is also very clear.

Dial comparison: Further observing the two, both dials are silver-plated. The silver dial is matched with blued steel willow-leaf-shaped hands, which are crisp and neat. The colors of the two are in sharp contrast. The two small dials are symmetrical up and down and are the same size as the genuine product. Almost all the details of the dial of the ZF Portuguese chronograph can be faked to be genuine!


Watch glass comparison: The ZF IWC Portuguese chronograph also uses convex sapphire crystal glass and has double-sided anti-reflective treatment, so that people can read the time clearly from any angle. In addition, it also uses the same blue-coated film process as the genuine watch glass. Due to taking pictures on a cloudy day, the blue-coated film effect cannot be photographed. Bokey will make it up next time.

Case thickness comparison: Watch fans who have bought the Portuguese chronograph before should all know that the old version is thick due to the limitation of the movement, which is a shortcoming of the Portuguese chronograph. The Portuguese chronograph produced by the ZF factory this time uses the Dandong 7750 movement. After improvement, the thickness is the same as that of the genuine product. Its case is installed in three parts: bezel, middle case and back cover, instead of the one-piece press installation of the old version. In addition, because the movement has removed redundant modules, the stability is greatly improved!

Let’s compare from another side. Previously, some watch fans used a small trick to distinguish between genuine and fake versions. That is, it is judged according to whether the left and right buttons and the middle crown of the genuine product are not on the same horizontal line. Of course, after the ZF ultra-thin Portuguese chronograph appears, this little trick will be self-defeating, because ZF achieves a one-to-one ratio with the genuine product. The two buttons and the middle crown are not on the same horizontal line. However, we can still see that under the hands of the genuine product, it is completely blue, while ZF still shows some white. This is also a skill to distinguish authenticity. I hope that the ZF Portuguese chronograph can improve this flaw in the later stage!

Back cover comparison: Let’s focus on looking at the engraved words on the back cover. After careful comparison, Bokey found that the English engraved words are in line with the genuine product and there is no problem. As for the number below, the engraved words of the genuine product are slightly larger than those of ZF, and the font color is also darker mainly because the genuine product has been used.

It is more obvious after the picture is enlarged, but it is difficult to notice at the back cover position and it is harmless.


Buckle comparison: The brushed treatment of the buckle is delicate and smooth, and the proportion and size are the same as the genuine product.
The IWC engraving on the buckle of the ZF Portuguese chronograph is slightly larger than that of the genuine product, and the font is thicker. The genuine product is relatively slender.

After opening the buckle, the workmanship inside is fine and worthy of praise. ZF still pays great attention to detail processing.


Strap comparison: The genuine product uses a black crocodile leather strap, and ZF uses a dark blue cow leather strap. There is not much comparability. Watch fans who pursue perfection can find Bokey to buy and replace it with a crocodile leather strap. As for the color, the genuine product is also available in dark blue and black.


Summary: The breakthrough of the ZF factory V2 version of the Portuguese chronograph in thickness this time really shocked many watch fans. Not only the genuine product is pursuing meticulous craftsmanship, but the replica market is also constantly striving for excellence. Friends who like the Portuguese chronograph must not miss this ZF factory V2 ultimate version of the Portuguese chronograph!
(In addition, some merchants boast that ZF has released V3 or several versions to increase the price and deceive buyers. Please watch fans keep their eyes open. So far, ZF is still the V2 version. The manufacturer promotes it as the V2 ultimate version of the Portuguese chronograph!)
