The most popular watch series of IWC is undoubtedly the Portuguese series. Speaking of which, the Portuguese series can be regarded as a series with very high aesthetics among IWC watches. It is masculine while not losing elegance and is a must-have for a refined gentleman. As the aesthetic representative of the IWC brand, the Portuguese seven-day chain (Portuguese 7) and the Portuguese chronograph (Portuguese chrono) often make watch enthusiasts indecisive. The most popular watch series of replica IWC is undoubtedly the Portuguese series. Speaking of which, the Portuguese series can be regarded as a series with very high aesthetics among IWC watches. It is masculine while not losing elegance and is a must-have for a refined gentleman. As the aesthetic representative of the IWC brand, the Portuguese seven-day chain (ZF V5 version Portuguese 7) and the Portuguese chronograph (ZF V2 version Portuguese chrono) often make watch enthusiasts indecisive and unsure how to choose between Portuguese 7 and Portuguese chrono. In fact, the most popular styles of these two watches are both white dials with blue markers. We have to admit that their aesthetics are extremely high. At first glance, I was deeply attracted. So, how should we specifically choose? Today, Bokey Watches will talk to you about the differences between these two watches.



The Portuguese series seven-day chain is commonly known as “Portuguese 7” because it has an extremely long seven-day power reserve time. The watch dial has two small dials on both sides. The 9 o’clock position is the second hand dial, and the corresponding 3 o’clock position is the power reserve display dial. Many watch friends will mistake it for the day display dial…

The Portuguese chronograph is a chronograph watch with the same white dial and blue markers design. The longest pointer staying at the 12 o’clock position is the chronograph hand. The 6 o’clock position is the regular second hand, and the 12 o’clock position is the chronograph minute dial.

Both watches adopt the process of coating the inner sapphire glass. Looking from the side, the reflective film is very beautiful. Both have blued steel hands and blued blue markers scales. Therefore, this kind of texture is closer to the genuine product. The blued steel hands have the same color as the genuine product, black in the dark and bright blue in the light! Very beautiful.


The two watches each have two small dials. For Portuguese 7, they are distributed on the left and right. The left side is the second hand dial, and the right side is the real power reserve display (note that it is not the day! It is used to display the power of the movement in real time). There is a trapezoidal calendar window at the 6 o’clock position. For Portuguese chrono, the two small dials are distributed up and down. The upper one is the second hand dial, and the lower one is the chronograph minute dial. The chronograph second hand that stops at the 12 o’clock position on the dial is usually stationary and only starts when the chronograph is started. The upper and lower parts of the crown of Portuguese chrono are the chronograph start/stop button and the chronograph reset button.


In terms of size:
The diameter of Portuguese 7 is 42.3mm, the thickness is 14.3mm, and the weight is 111 grams.
The diameter of Portuguese chrono is 40.9mm, the thickness is 12.3mm, and the weight is 87 grams.
So overall, Portuguese 7 is larger. The difference in dial diameter of 1.4mm will not make much difference in actual effect. However, in terms of thickness, Portuguese 7 is 2mm thicker than Portuguese chrono, which is still very obvious. Therefore, friends who don’t want to buy a large-sized watch should still consider Portuguese chrono. Portuguese chronograph is relatively thinner than Portuguese seven-day chain, and its power is far inferior to the 72-hour power of Portuguese seven-day chain. Portuguese chrono only has a 44-hour power reserve. But the two are very similar, at least in style.


On the back side: Portuguese 7 adopts a see-through back design, allowing for intuitive appreciation of the beautiful movement. While Portuguese chrono adopts a solid back design. In terms of the movement, ZF factory’s Portuguese 7 uses a customized Dandong long power reserve movement with a deck to replicate the cal52010 movement. The power reserve lasts for three days. Although it is not as good as the seven-day power reserve of the genuine product, it is still very rare among replica watches. The appearance of the movement has been upgraded and improved many times and is already very detailed. The fish scale pattern polishing and gemstone color are already very close to the original. The movement of Portuguese chrono uses Shanghai 7750, which is relatively thick. When installed in the case, the thickness can reach 13.5mm, while the genuine product is only 12.3mm. Therefore, ZF Portuguese chrono has brought revolutionary replica progress! It is also the thinnest Portuguese chrono on the market currently! In terms of stability, it is slightly worse than Portuguese 7! But after all, Portuguese chrono has a solid back and the movement cannot be seen. This point is better than Portuguese 7.


Strap and buckle: Both watches from ZF factory use calfskin with embossed crocodile pattern leather straps and original folding buckles. Of course, the texture of calfskin cannot be compared to crocodile skin. Although there is a difference in appearance, in actual wearing, crocodile skin is softer and more comfortable. Therefore, friends who care about this point are recommended to upgrade to a crocodile leather strap.


Summary: The two Portuguese series are equally matched in terms of aesthetics. The appearance varies from person to person. But in terms of authenticity, friends who are very concerned about authenticity are still recommended to choose the Portuguese chrono with a solid back design. Although the see-through back of Portuguese 7 is already very close to the original, but I believe watch enthusiasts have all heard the saying that a solid back has no flaws. In terms of movement stability, both watches are very mature models. Under proper operation, the stability of both watches is good. That’s all for Portuguese 7 and Portuguese chrono today.
