Hello everyone, this is Bokey. Old watch, new talk – The IWC Portuguese Seven-Day Chain series has always been loved by people all over the world. As a dress watch, this series must have its place. The Portuguese Seven is also a best-selling item at the official counter. Although the purchase price in foreign countries is close to 90,000 yuan in RMB, the watch has a diameter of 42.3mm and is also very suitable for Asian men’s wrists. In this issue, Bokey brings you a “evergreen tree” in the replica watch industry in recent years, the IWC Portuguese Seven-Day Chain, abbreviated as Portuguese Seven. In terms of the Portuguese Seven at the official counter, the back-through design has been changed again and again. Due to the high failure rate of the initial version of the Portuguese Seven, the official counter has made a revision. In 2016, the back-through was upgraded again. Approximately, the settings of the barrel and gears were modified to increase stability. As a representative of the replica watch industry, the ZF factory has also devoted itself to research and development and developed today’s V5 version of the Portuguese Seven. I believe this is also the final version, unless the official counter launches an improved version again. Now let’s take a look at some color options of the ZF factory Portuguese Seven V5 version.
Through the above high-definition pictures, you can beautifully see the various color styles of the ZF IWC Portuguese Seven. At present, the replica watch industry is a mixed bag. Many sellers post everywhere with high-definition factory pictures, but the goods sent to customers are from small factories, resulting in many novice watch enthusiasts being cheated. The replica watch industry is divided into different grades. The same style will be made by different manufacturers. When encountering unethical merchants, watch enthusiasts who don’t understand the craftsmanship will be completely fooled and buy it. Therefore, Bokey reminds the majority of watch fans here to play watches transparently and prevent falling into misunderstandings and being cheated! The highest version of the Portuguese Seven is now produced by ZF. It can be said to be at the level of indistinguishable from the genuine product. It is enough to appreciate the degree of replication and indistinguishable level between ZF and the genuine product. It’s hard to tell the real from the fake! So when playing the Portuguese Seven, you must definitely recognize the highest version of ZF V5. The most indistinguishable one is it.

Bokey mainly shares and evaluates the most popular white dial with blue hands model here. The specific model is: IW500107. It is a 1:1 replica based on the genuine product. In terms of diameter, it maintains the same 42.3mm as the genuine product. The thickness is also 14mm. The movement is the latest replicated 51011 movement. In terms of appearance, it is as beautiful as the genuine product. Although the kinetic energy is not as exaggerated as the genuine product’s seven days, it can last for about three to four days in actual testing. This is a breakthrough in the field of replica watches!
First, looking at the front of the watch, the color matching is very neat, clean and generous. The pointers of the ZF IWC Portuguese are all blued steel pointers. The pointer scales of ZF are as round as the genuine product. The dial of the watch uses the low-key white color with the high-cold blue Arabic numeral scales, showing noble temperament. In the center of the dial are the hour and minute hands. The 3 o’clock and 9 o’clock positions are two small dials, which are the power reserve display and the small seconds dial respectively. Many watch enthusiasts who are not familiar with the Portuguese Seven will mistake the power reserve display at the 3 o’clock position as the week display function and often worry because they don’t know how to adjust it..

The mirror of the Portuguese Seven is made of sapphire crystal and is coated with a blue anti-glare film. Under reflective conditions, you can see the blue reflection. Like most IWC watches, the ZF IWC Portuguese Seven IW500710 sea blue face replica still uses a double-sided light blue high-transparency anti-glare coating. For ZF, which owns nearly 20 genuine IWC watches, this is not difficult. The function of the coating is to change the lighting of the glass. The purpose is to make the glass mirror more transparent and provide a convenient and clear timing environment. Looking from the side, the screw-in crown enhances the waterproof function. The end surface of the bezel is engraved with the brand logo. The side of the crown has tooth pattern decoration for convenient time adjustment and anti-slip. The lug protrudes slightly outward, which is very beautiful and three-dimensional.

Now let’s take a look at the literal details of the ZF factory. PS. The pictures are all magnified several times.
Below the 12 o’clock position is the brand logo of IWC. It is printed by oil pressure printing process and looks very three-dimensional and oily. The side case uses horizontal brushed finish, and the brushed finish is very fine. The corners are polished very exquisitely and feel very round when touched. The height of the mirror also appears to be slightly curved. The right crown is also exactly the same as the genuine product. The LOGO engraved on the top of the crown is the same as the genuine product and is difficult to distinguish with the naked eye.

The 3 o’clock position is the power reserve display. The red paint in the disk indicates the energy supply situation. The 9 o’clock position is a small seconds dial. Both small dials have concentric circle patterns for decoration.

In fact, this power reserve display will automatically rise when worn on the hand and will drop down when not worn. It can also be manually replenished with kinetic energy in the form of winding. When winding, you will find that the pointer in the kinetic energy display disk is also moving. Regarding kinetic energy, I still need to tell you. This is also a problem that many friends ask about the most. First of all, the original kinetic energy storage is for seven days. According to the actual test by Bokey of the ZF factory Portuguese Seven, the kinetic energy storage of ZF is generally maintained at about 72 hours. So the difference in kinetic energy from the original is relatively large. But it is an automatic mechanical model. When wearing it for the first time, wind the kinetic energy disk to about 5. As long as you wear it normally every day, you don’t need to wind it.

The pointers of the ZF factory IWC Portuguese Seven are blued steel. Looking at it from the front, the pointer color is black. Looking at it from a reflective angle, it appears blue. This is the characteristic of blued steel.

At the 6 o’clock position is a calendar window. The window is chamfered and is consistent with the genuine product. Here is a brief talk about the calendar problem. Undeniably, the calendar is indeed a pain point of the Portuguese Seven. In previous evaluations, it has also been said that the Portuguese Seven has a problem of calendar deviation. But this does not occur in every model and needs to be screened.

Looking at the overall dial again, the overall tone is white. After correcting two problems that existed in previous versions, it is now indistinguishable from the genuine product in color. The dial color is full of fashion sense. The outermost circle of the dial is the track minute scale circle, which is also very distinctive. Inside is the Arabic numeral hour markers. The hour markers are embedded on the white dial. The surface of the hour markers is polished, and the layering is very obvious. The 12 Arabic scales are made with embossed workmanship (180-degree engraving and polishing) to make them round, textured, smooth and fluent.

The side case uses horizontal brushed finish, and the brushed finish is very fine. The corners are polished very exquisitely and feel very round when touched. The height of the mirror also appears to be slightly curved. The right crown is also exactly the same as the genuine product. The LOGO engraved on the top of the crown is the same as the genuine product and is difficult to distinguish with the naked eye.



The ZF Portuguese 7 is powered by a Dandong-replicated Cal.51011 automatic movement, featuring meticulously decorated plates with a combination of perlage (fish-scale pattern) and Geneva stripes. Upon closer inspection, the movement reveals ruby jewels and gilt engraving. This cloned movement achieves an impressive 3-4 days of power reserve while maintaining remarkable stabilit

The back cover material is also sapphire glass.
The strap is matched with a cowhide strap. For the white dial model, generally only black and dark blue colors are available. For other models, different color straps can be matched. For better comfort, a crocodile leather strap can also be matched. At the same time, it is also a relatively powerful configuration!


The clasp is synchronized with the new folding clasp of the genuine product. And the effect of the IWC logo is also synchronized with the genuine product. It is concave. Small factories on the market are all flat.



Reference for wearing pictures. Bokey wrist circumference is 15.5CM.
