IWC Portofino IW459401 MKS Factory Review

IWC Portofino IW459401 model is produced by MKS Factory with an 18K thick gold-plated case, standard case diameter and high-precision automatic Super Clone 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.


Many watch enthusiasts may hesitate, thinking that this moon phase function is complicated and prone to problems. In fact, the structure of this function is not complicated at all; In other words, the moon phase is not considered one of the complex mechanisms of the watch. It's just a matter of adding a few gears and adjustment mechanisms according to a certain transmission ratio. A “half-moon” shaped window opens on the dial; The moon phase disc is usually made with a dark blue background and has two symmetrical patterns, two round moons, and a sky full of stars in between. In concert with the dial window, first quarter, full moon, and last quarter appear sequentially as the moon phase disc slowly moves. The most typical lunar phase disk has 59 teeth and is advanced by one tooth each day; Thus, the rotation period of each group of moon patterns is 29.5 days, which symbolizes the lunar cycle. It is of little practical use, it is neither fully understood nor read correctly; It is merely a decorative and eye-pleasing function. According to Abi, it doesn't have much meaning other than being beautiful and cute.
I'm sure everyone feels unfamiliar with MKS Factory. It is a well-established replica watch factory that started its business with IWC Mark models and operated in the same period as N Factory. The name MK comes from the initials of the word Mark; It was renovated and restructured two years ago and named MKS Factory. It is a brand with affordable prices, good workmanship and reliable products. Portofino, with its classic three hour and minute hands, is also one of the flagship products for MKS Factory for many years; It is the first choice of beginners at entry level. So they have a certain experience and a certain power to make this Portofino moon phase model. Below will briefly tell you the highlights of this Portofino moon phase wristwatch.
Manufacturer blurb: MKS introduces its new product — the Portofino series moon phase automatic wristwatch! It is full of great “original” subtleties.
1. IWC produces the Cal.35800 movement with real moon phase function exclusively, with great investment and under its monopoly; Most other models on the market use a day-night disc!
2. The only factory on the market with Portofino's bar nail processing technique; It is exactly the same as the effect of the original workmanship, the overall texture of the dial surface is even better.
3. With the support of the specially produced mechanism, the dimensions are exactly the same as the original: 40 * 11.1 mm. Other versions on the market are much thicker.
Summary in one sentence: Function and size are in line with the original, reproduction success is high. The manufacturer offers three color options; Blue gives a younger vibe, while rose gold looks luxurious. The choice is yours.



MKS Factory IWC Portofino vs AI Factory replica: Which is better?

Let's compare the two factories' IWC Portofino moon phase models from the front.
MKS Factory has integrated the edges and corners of the crown LOGO part. The AI Factory crown has a gradual structure. At this point AI completely loses in comparison.
MKS Factory used more three-dimensional stick studs on the dial hour markers, and all of them were edge-corner engraved. In AI, there is no three-dimensionality, no rendering. In the comparison here, AI loses completely again.
MKS Factory processing is smooth. AI Factory is protruding and does not match the original. Again the AI loses completely.


Here, MKS Factory has added an independent button control to adjust the moon phase separately. In our AI Factory model, there is no this control button. However, this Portofino moon phase model in the showcase has a button. Therefore, AI Factory loses at this point.





The simple Portofino model, produced two years ago, was appreciated by users in the market. Now the same moon phase model as in the showcase has been added; Moon phase function synchronized with original factory. Although the moon phase is a decorative function for us, it is not easy to achieve an exact moon phase cycle every month. The basic mechanism is the Japanese Citizen; It is simple, durable and its thickness perfectly matches the thickness of the original watch body. There were actually manufacturers who already made this wristwatch, but it was not perfect; Either the thickness did not match the original, the moon phase was not working properly, or the workmanship of the dial surface was poor. This IWC Portofino model from MKS has solved the above problems perfectly! Customers who want a higher level can upgrade to crocodile leather; so the overall texture goes up a notch!
Summary: AI Factory has a long way to go when it comes to detail. The processing is missing in many places, the workmanship is a bit rough. We can say that the workmanship and details of the MKS Factory IWC Portofino moon phase replica watch surpass every other version on the market. With the support of the specially produced mechanism, its workmanship is also in line with the original. If you like it, buy it without thinking, hesitating or delaying.
I hope this article was useful to you. We will share more detailed disassembly, real shot review and real-replica comparison in the future.
