The IWC Portugieser collection has long been beloved by watch enthusiasts worldwide. When it comes to dress watches, this series is indispensable. The Portugieser 7‑Day is a huge best‑seller at boutiques, even though its overseas price converts to roughly 70,000 RMB. Measuring 43 mm in diameter, it fits Asian men’s wrists very well.
Today we bring you an “evergreen model” in the replica‑watch community: the IWC Portugieser 7‑Day, commonly known as the Portugieser 7. For the genuine boutique model, the display case‑back has gone through multiple revisions. Early‑generation Portugieser 7‑Day watches suffered from high failure rates, prompting an official factory revision. In 2016, the display case‑back was upgraded once more, with adjustments to the barrel and gear configuration to boost reliability.
As a leading replica manufacturer, ZF Factory invested extensive research and development to create today’s V5 version of the Portugieser 7. I believe this is the definitive iteration, unless the genuine brand releases another updated model.

The dial features blue Arabic numeral hour markers together with a railway‑style minute track, a signature design element of the Portugieser collection. Both front and rear crystals are made of sapphire glass, finished with IWC’s signature blue anti‑reflective coating as standard equipment.
Earlier versions suffered from two known issues. First, the dial took on a yellowish tint, appearing noticeably more yellow than the crisp white of the genuine watch. Second, dust particles would get trapped beneath the dial surface. This dust‑trapping flaw was likely caused by the dial‑coating formula.
Fortunately, ZF Factory is a reasonably responsible manufacturer. They offer free dial cleaning or replacement services for affected units. Customers who purchased the Portugieser 7‑Day from us and encounter the dust‑under‑dial issue are welcome to contact us to send their watch in for servicing. With the release of the V5 version, ZF Factory has fully resolved both of these previous shortcomings.
It features applied three‑dimensional numeral hour markers. ZF Factory captures fine genuine‑watch details exceptionally well. Older versions had numerals entirely coloured blue. After the upgrade, the markers match the genuine: their reflective surfaces show silver when catching light. This subtle detail goes unnoticed by many watch enthusiasts. Refer to the 11‑o’clock marker in the picture below — its reflection appears silver with a mirror‑like effect.
Just like the date window on the genuine watch, the replica also features curved‑edge finishing. The printing is an exact match. Every scale marker is free of burrs and raised spots, and the date disc sits perfectly centered without any offset.
The small‑seconds sub‑dial on the left‑hand side of the dial serves as the power‑reserve indicator, and its reproduction is highly accurate. The dial exhibits excellent craftsmanship. In particular, the two‑colour overprinting (red and black) on the power‑reserve sub‑dial is exquisitely executed. The red section acts as a low‑power warning when the watch is nearly out of energy. The red coating has tangible depth and a raised three‑dimensional effect.
The hand shown in the picture below is the seconds hand, with crisp and refined finishing.
After revisions for the replica V5 version, the thickness and proportions are identical to the genuine watch. The edges and corners have been finely finished following genuine‑watch specifications. The brushed treatment on the case is nearly flawless. The crystal features a subtle domed curvature. Unlike the Portugieser Chronograph, the Portugieser 7‑Day case is assembled from three separate components: the bezel, middle case and case‑back. Its hand‑feel is fully comparable to that of the original.
The case‑back is built strictly according to genuine‑watch specifications. Notches are located around the bezel for tool‑aided disassembly. It adopts a screw‑in sapphire display case‑back, with non‑repeating serial‑number engravings.
After lengthy revisions and fine‑tuning on the ZF Factory Portugieser 7‑Day, the internal structure and thickness of its movement are nearly identical to the genuine watch. The movement bridges feature exquisite perlage and Côtes de Genève finishing. Jewel bearings are set into the bridges alongside gilded engravings. Viewed from the case‑back side, the overall appearance bears virtually no visible difference from the original. Furthermore, the replica has addressed rotor noise; only soft mechanical running sound can be heard.
The movement bridges feature exquisite decorative finishing. The edges are newly decorated with perlage. The only difference is that all gears rotate when manually winding the genuine watch, while some gears on the replica serve purely decorative purposes.
The ruby jewels feature enhanced colour, delivering greater visual transparency.
The black‑coloured gear component shown in the picture is the Pellaton winding system, made of ceramic on the genuine watch. To achieve an identical visual appearance, the replica applies decorative finishing to this part. In reality, this gear does not rotate during watch operation, yet this does not affect daily performance.
Great effort has gone into the replica’s buckle. Its outer design, brushed details, edge polishing and structural reproduction are all executed to a very high standard. Crafted using the same techniques as the genuine article, it is fully interchangeable with the original buckle.
Summary: The IWC Portugieser 7‑Day is a long‑time best‑selling staple within the replica‑watch community. At present, no other factory can match ZF Factory’s level of accuracy. Building upon the V4 version, the V5 brings further refinements while keeping the same price point, delivering a refreshed experience for many IWC enthusiasts. Do not miss this model if you are a fan of the Portugieser 7‑Day!
