ZF Factory IWC Portofino Chronograph Function User Manual and Review of the Watch Under a Few Headings

First heading – Overview of the ZF Factory IWC Portofino chrono: This watch is entirely made of 316 steel, sapphire glass and calfskin; It also comes with a modified 7750 movement. The feel is quite good when worn on the wrist. A plating process has been applied to the case, the processing result looks very shiny; All functions work smoothly. An extremely sporty watch. ZF hand-machined the case, giving it a perfectly round curve; It carries the highest level of polishing and processing workmanship in the industry. The lines are fluid, the shine is eye-catching; The 'fake at a glance' embarrassment that may arise during use is completely avoided. In general, the texture feeling of the watch is also very satisfactory. Those who love the Portofino chrono can continue reading the rest of the article; will make a brief evaluation here. I will also briefly explain below the instructions for using the watch and some problems to avoid in the future.

Second heading – Function user manual of the ZF Factory IWC Portofino chrono: Functions are also a subject that confuses many watch lovers. The practicality of the functions in 7750 multifunctional chronograph watches is appreciated by watch enthusiasts. Below, I explain the use of the watch's functions and the points to consider. The 9 o'clock position is for the seconds (small seconds drum), the 12 o'clock position is for the 30-minute chronograph, and the 6 o'clock position is for the 12-hour chronograph. The above function drums are all operated by the buttons on the right (mushroom-shaped buttons at the top and bottom). Function usage: The top button starts and stops the chronograph; the crown in the middle, with which you set the time normally (hidden function: you can set the day and date by pulling it out one step and turning it up and down — note: 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 second hand moves one turn, the upper small drum advances one digit; When it makes one revolution, the small drum at the bottom advances one digit. Caution: Do not overuse the chronograph function at normal times, otherwise you will increase the load on the movement; Also, lay the watch flat when not wearing it. In a functional watch, it is necessary to know how to use it first and then enjoy it. If there are still unclear points, you can consult directly.

Third heading – Case review of the ZF Factory IWC Portofino chrono: Overall dimension 42 mm; This is a diameter suitable for the usage habits of almost all watch lovers. The metal part of the case is 316L stainless steel, and a plating process has been applied to the steel, which makes the watch look brighter overall. Also molded to match the original; The line feel of the case is quite evident. Let me point out this: The stainless steel material in domestic watches is basically always of this type; This steel does not deform easily and is very easy to mold. Of course, no material, no matter how hard, can withstand impacts and falls. During the after-sales process, I have seen many watch enthusiasts encounter damage caused by impact. Be sure to protect your watch; You can only preserve its beauty when you protect it.

Fourth topic – Sapphire glass review of the ZF Factory IWC Portofino chrono: IWC watches have a basic common feature: In most watches, a double-sided blue coating (AR anti-reflective coating) is applied to the sapphire glass. This technique is, firstly, to provide transparency to the watch, and secondly, to reduce light reflection so that the data can be read more easily. I also mentioned in my previous posts: How can you tell whether the glass of a watch is sapphire? Because ordinary glass is now used in many lower segment watches; It is useful for you to know this. If it produces a clear and high-pitched sound when lightly tapped, it is sapphire. There is a misconception here that everyone should know: Some users say 'if it does not disperse when water is dropped, it is sapphire', this is a wrong understanding; because the liquid has its own surface tension. Again, some users asked 'won't sapphire break?' he asks. We need to think about this issue with common sense: What can withstand being hit hard? Knowing your value is the beginning of everything.

Fifth topic – Review of the dial surface and hour markers of the ZF Factory IWC Portofino chrono: What stands out most directly behind the sapphire glass is the dial surface. The Portofino chrono has several different dial combinations; But as the Studio, our favorite is this white dial and gold hour and minute hands model. There's no other reason, just for the look. This is truly an era where charisma matters; The white dial and gold hour and minute hands are truly fascinating. The effect of the text printing is also extremely finely crafted. The date window has a bevel; Even this small detail proves the care and workmanship of the factory. Each hour marker stick is fixed by spot welding on the back surface of the dial to prevent it from falling out due to impact (still, it is necessary to protect the watch well). General gold parts are gold plated; This minimizes the risk of gold oxidizing and creating an embarrassing appearance. The pattern design of the function drums on the dial surface is very clear; There is no such 'mess' at all. Credit goes to ZF Factory here — a real save!

Sixth heading – Side profile review of the ZF Factory IWC Portofino chrono: As I said above, the case is entirely 316L stainless steel; The side surface is also molded from this material. Of course, here we examine the workmanship on the side profile again. The function buttons have real functions like other functional watches; However, the buttons of the Portofino chrono have a slightly mushroom-like structure, and they do not give you the feeling of pricking your finger when you press them. Of course, the design style of each watch is different. The IWC logo on the side surface of the button is very clearly processed; Since the new watch is covered with a blue protective film, it does not look very clear, but when you remove the film and enlarge it, the workmanship detail is really pleasing to the eye. Details often determine success or failure; The smaller the detail, the more it reveals the power of the factory.

Seventh heading – ZF Factory IWC Portofino chrono back and movement review: Like the Portugieser Chronograph, this watch also has a closed case back design; The back cover is fixed with screws, and the writings on the cover are also very clear. Screw pattern design is used in the hub part in the middle; The general line feel is quite distinct, there is no so-called 'stinging' feeling. A watch friend previously asked: Will the back cover of the Portugieser Chronograph sink into the hand? Because the hub of the Portugieser Chronograph is brushed steel, that's why it feels like that; Of course, this is to get as close to the original effect as possible. A modified 7750 was used as the mechanism; After this mechanism was modified, the functions became synchronized with the original and the thickness became considerably thinner. This is one of the cares taken by the factory. (Note: The sound of the automatic winding wheel on the back of this mechanism is very low.)

Eighth heading – Strap and buckle review of the ZF Factory IWC Portofino chrono: For the strap, the ZF factory this time applied a polishing and crocodile texture printing process to the original calfskin; This made the overall style more dynamic. Of course, the crocodile leather strap option can also be preferred; This is the most stylish and flashy option right now. The biggest advantage of crocodile skin is that it gets brighter with use over time. This is up to the choice of you who love your watch; Of course the original strap is also very nice. The buckle part is processed in a way that does not create too much resistance and wear out the strap when attaching and removing the strap; The buckle is also very careful.

Conclusion: As the Studio above, we briefly evaluated the ZF Factory Portofino chrono; We explained the use of the function and also touched upon the points that should be taken into consideration during use. The workmanship of the watch is very good; But it is also necessary to know how to truly enjoy this watch and how to protect it. That's all I have to share for today. I also welcome watch lovers from all walks of life here to discuss watch knowledge. There is no end to learning per hour; You can only gain greater mastery by constantly improving yourself. Thank you all for watching!
