ZF Factory IWC Portofino Chronograph Workmanship Review

The IWC Portofino model is produced by ZF Factory with a solid stainless steel case, 42 mm 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.

How is the workmanship of the ZF Factory IWC Portofino? Is it obvious that it is fake at first glance?

Looking at the overall details of the watch, the workmanship of the ZF Factory Portofino is impeccable; It is at a level that rivals the original and is very difficult to distinguish from the real thing. The diameter of the watch is 42 mm and this measurement exactly matches the original. The case is made of 316 stainless steel; It has undergone the highest level of polishing and processing, the result is the same as the original. The lines are fluid, the texture is smooth, and the case has an extremely perfect curve.

When using chronograph watches, you should pay attention to the following: do not keep the chronograph function on for a long time, otherwise you will increase the load on the mechanism. Also, do not use the longest chronograph hand as a seconds hand; Be sure to learn the function distribution of the dial well! 9 o'clock is the seconds hand (small seconds dial), 12 o'clock is the 30-minute chronograph, and 6 o'clock is the 12-hour chronograph. The buttons on the right (top-bottom mushroom shaped) are used to operate the function dials above. Usage introduction: the top button starts and stops the chronograph, the middle one is the normal time setting button (hidden function: you can set the day and date by pulling it out one step and turning it up and down! Attention: when the watch is working normally, the day and date advance automatically, no manual intervention is required!), the bottom one is the reset button. When the large seconds hand makes one revolution, the small dial at the top moves one notch; When it turns one turn, the small dial at the bottom moves one notch.

The gold-coloured Roman stick hour markers have gained an even more textured appearance after undergoing ZF's fine engraving. The length and size of the three hands are exactly the same as the original; The printing of the 60-second chronograph markers on the inner ring is neat and the proportion is perfect. The small dial at 12 o'clock is the 30-minute chronograph dial, the small dial at 9 o'clock is the running seconds dial, and the dial at 6 o'clock is the 12-hour chronograph dial; All three small dials are very carefully crafted. There is a dual calendar function at 3 o'clock that shows date and day; window sizes are even, there is a sense of layered depth, and the type printing is clean and neat; no ink bleed.

Although the watch generally looks very simple and elegant, some details give a hint of sporty liveliness. For example, the number 30 on the minute chronograph dial and the number 12 on the hour chronograph dial are marked in eye-catching red. A closer look shows that the CD patterns on the three small dials of the ZF IWC Portofino Chronograph watch are very finely crafted; It is truly admirable. Blue coated sapphire glass on sapphire crystal was used as glass; It is extremely clear, anti-reflective and reading the time is quick and clear.

The IWC brand logo on the crown of the watch is clearly engraved, and the triangular pattern recesses are processed smoothly and consistently; This shows how much importance ZF attaches to the visual fidelity of the watch. The chronograph pushers on both sides of the crown are in a striking funnel shape; This type of design is also frequently seen in the cockpits of Italian sports cars.

The IWC Portofino Chronograph has a closed case back design; The outer ring of the case back is tightly fixed with 6 screws, protecting the mechanism against shock and impacts. The middle part that touches the wrist has been treated with a matte finish, giving the case back a more textured feel; The workmanship of the English letters engraved on it is also extremely fine. Inside the watch, the stable Shanghai 7750 movement is used, converted into the original Cal.79320 caliber; Not only do all the functions match the original, but the feeling of use also matches exactly.

The strap is made of imported brown/black calfskin; The bamboo knot pattern on the strap is clear, the brown stitching is tight and neat. Its texture is soft and its flexibility is high; Paired with a polished stainless steel pin buckle, making it safer, sturdy and practical to use. The IWC logo on the buckle gives a very distinct three-dimensional feeling.

In general, the watch reflects the aesthetics of the original to the highest possible level; At the same time, the functions of the Portofino Chronograph have been adjusted to match the original.
