ZF Factory IWC Portugieser Seven Days Power Reserve V5 Version Blue Dial Review

The IWC Portugieser model is produced by ZF Factory with a solid 316L stainless steel case, standard case diameter and 7750 automatic chronograph movement architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.

1. [Case] The overall design is flashy and pleasing to the eye, with a simple but luxurious appearance. Relief-style dial hour markers are highly three-dimensional, sapphire glass front, all-new screw-in sapphire glass case back. In order to capture the brightness of the original, ZF uses imported 316L stainless steel casting; Its cost is several times higher compared to ordinary 316L. The challenge with this case is the slight curve at the ear; Even after the case draft is completed, every experienced ZF master watchmaker needs to finely process it, only then can the same tooling experience as the original be achieved (the efficiency rate is generally kept around 60%). The all-new screw-in sapphire glass back cover is the same design as the original.

2. [Dial] 12 Arabic numeral hour markers are engraved with embossed technique (engraved at 180 degrees), thus giving a rounded and textured, smooth and flowing appearance. The willow leaf-shaped hour and minute hands are treated with rhodium plating, mastered by ZF; In this way, it preserves its shine and elegance for as long as possible. The small dial at 9 o'clock is the small seconds dial, and the small dial at 3 o'clock is the power reserve indicator. Additionally, the CD pattern on the dial surface is faintly visible; It is thin, clear and its workmanship is extremely high.

3. [Glass] Like most IWC models, IW500710 uses double-sided light blue, high transmittance, anti-glare coating; This is not difficult at all for ZF, which has almost 20 original IWCs in its possession. The function of the coating is to change the light transmittance of the glass; The aim is to make the glass surface clearer and provide a comfortable, clear watch reading environment. The design of the date window gives a sense of layered depth; The chamfering of the date window creates a slight curve and enhances the appearance.

4. [Crown] The crown is extremely elegant and is engraved with IWC's classic logo; The triangular notch pattern is smoothly and consistently processed, flawless. The brushed workmanship of the case, especially the brushing on the side surface, is extremely fine; The highest level version of the industry, reflects the workmanship of the large factory in every detail, very meticulous.

5. [Mechanism] It carries ZF Factory's own improved cal.52010 replica movement based on 7750; It works precisely and reliably. Since ZF Factory corrected and adjusted the Portu 7 for a long time, the internal structure and thickness of the mechanism are very close to the original. All bridges of the mechanism have been processed very carefully; There are fish scale and Geneva wave pattern workmanship, ruby ​​decorations and gilded relief writings on the bridges. The back of the mechanism does not show any difference when viewed as a whole; Moreover, the sound of the automatic winding hammer has also been corrected, only a slight mechanical rotation sound can be heard. The workmanship of the mechanism bridges is extremely elegant, and a new fish scale pattern has been added to the edges. The only difference is that when manually wound, all the gears work in the original, while in ZF Factory, some gears are only for decorative purposes!

Detailed Review and Features

6. [Strap] As the top-end IWC Port 7 on the market currently, ZF has chosen the folding buckle; It brings back the original exactly. Whether it is the overall brushing work or the chamfer polish on the edges, it is all extremely fine and elegant; It offers a high level of quality.

We can say that this Port 7 of ZF Factory is a rare, top-notch work in terms of both detail and workmanship. The V5 version takes the previous V4 version to the next level; The price has not changed. This really brings a new experience to many IWC fans. Those who love Port 7 should not miss this opportunity.
