ZF Factory IWC Portofino chronograph function user manual and review of the entire watch under a few headings

First heading — General review of the ZF Factory IWC Portofino crown: This watch is entirely made of 316 steel, sapphire glass and calfskin; In addition, it is equipped with a modified 7750 movement. The feeling on the wrist is very good. The case has been applied a plating process, its processing is extremely bright, at the same time the functions work normally; It is a very sporty watch. ZF has recreated the case with a perfectly round curve by hand-machining it; It features the industry's highest level of polishing workmanship, its lines are fluid, its shine is eye-catching, and it completely eliminates the 'fake at first glance' embarrassment that may occur when worn. In addition, the general texture of the watch is also extremely striking. Portofino crown lovers can continue reading the rest of the article; will briefly describe the watch! I will also briefly explain below some explanations of the use of the watch and some problems to avoid in the future!

Second title - ZF Factory IWC Portofino crown's function user manual: Functions are a point where many watch lovers are confused. The usefulness of the functions in the 7750 multifunctional chronograph watch is appreciated by watch enthusiasts. Below I explain the use of the watch's functions and the points to pay attention to! Position 9 is the seconds hand (small seconds dial), position 12 is the 30-minute chronograph, position 6 is the 12-hour chronograph. The operation of the function dials above is provided by the crown and buttons (top-bottom mushroom shaped) on the right. Usage description: The top button is for starting and stopping the chronograph; the middle one is the normal watch winding crown (hidden function: day and date can be adjusted 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 completes one revolution, the small dial at the top advances one notch; When it rotates, the small dial at the bottom moves one notch. Caution: Normally do not overwork the chronograph function, as this will increase the load on the movement; Also, please lay the watch on a flat surface when not wearing it! The first thing about a functional watch is knowing how to use it, and the second is knowing how to play with it. Watch lovers who still do not understand the points can consult directly!

Third heading — Case review of the ZF Factory IWC Portofino crown: The overall size is 42 mm, suitable for the wearing habits of almost all watch enthusiasts. The metal part of the case is 316L stainless steel; The steel has also been given a plating process, making the watch brighter overall, and is molded to match the original. The line feel of the case is quite strong. Let me also point out: the stainless steel material of domestic watches is almost entirely of this type; This steel is not easily deformed and is also easy to mold. Of course, no material, no matter how hard, can withstand impact. We have seen many watchmakers damaged due to impact during the after-sales process. Be sure to pay attention to the time; Only with care can you preserve beauty!

Fourth topic — sapphire glass review of the ZF Factory IWC Portofino crown: IWC watches have a basic common feature: a double-sided blue coating (AR anti-reflective coating) is applied to the sapphire glass of most watches. This technique is first to give clarity to the watch, and secondly to reduce light reflection and read the data more easily. I also mentioned in my previous posts: how to tell whether the glass of a watch is sapphire or not! Because ordinary glass is now used in many low-quality watches, it is good to know this! If the glass produces a high-pitched, clear sound when lightly tapped, that glass is sapphire. There is a misconception here that everyone should know: some people say 'if it does not disperse when water is dropped, it is sapphire'; This is a wrong understanding, because liquid has its own surface tension! Also, some people ask 'isn't sapphire glass breakable?' he asks. This question should be approached with common sense: what can withstand a hard blow? Taking care is paramount!

Fifth topic — Review of the dial surface and hour markers of the ZF Factory IWC Portofino crown: What stands out most directly behind the sapphire glass is the dial surface. The Portofino crown has several different dial combinations; But his favorite is this white dial gold hand version. Not for any other reason, just for its beauty. This is truly an age where charisma comes to the fore; The white dial and gold hands are truly fascinating. The workmanship of the text printing is also extremely fine. 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 of the dial to prevent it from falling off after impact (still, it is necessary to protect the watch well). General gold color parts are gold plated; This prevents the embarrassing situation of gold oxidizing as much as possible! The pattern design of the function rings of the dial is very clear, no confusion arises! ZF Factory should be appreciated here; It was truly a work of penance!

Sixth heading — Side face review of the ZF Factory IWC Portofino crown: As I mentioned above, the watch is entirely 316L stainless steel; The side face is also molded from this material. Of course, what we examine here is the workmanship of the side face. The function buttons have real functions, just like other functional watches; However, the buttons of the Portofino crown have a slightly mushroom-like structure and do not give a feeling of stinging to the finger when pressed. Of course, the design style of each watch is different. The IWC logo on the side of the crown is made very clearly; Since the new watch has a blue protective film, it is not very clear, but when the film is peeled off and enlarged, the workmanship detail is truly remarkable! Details often determine success or failure; The smaller the detail, the better it reveals the power of the factory!

Seventh heading — Back and movement review of the ZF Factory IWC Portofino chronograph: Like the Portugieser Chronograph, this watch also has a closed back design; The case back is fixed with screws, and the engravings on the case back are very clear. The groove design is used in the sole part in the middle, the overall line feeling is quite strong, and there is no feeling of scratching the finger. A watch friend previously asked 'Does the case back of the Portugieser Chronograph scratch the hand?' he asked; Because the middle base of the Portugieser Chronograph is brushed steel, it feels like that. Of course, this is to get as close to the original effect as possible. The improved version 7750 was used as the mechanism; After this mechanism was improved, while the functions remained synchronized with the original, its thickness became considerably thinner, which is a point that the factory paid attention to! (Note: The sound of the automatic winding wheel on the back of this mechanism is very low.)

Eighth heading — ZF Factory IWC Portofino crown's strap and buckle review: Regarding the strap, this time the ZF factory has applied a polishing and crocodile pattern pressing process to the original calfskin; This makes the overall style more dynamic. Of course, there is also a crocodile leather strap option if you wish; This is the flashiest option right now. The biggest advantage of crocodile skin is that it becomes brighter with use over time. This is up to you who love the watch; Of course the original strap is pretty nice too! The workmanship of the buckle has been made in a way that prevents excessive force and damage to the strap while attaching it; The buckle is also extremely careful!

Summary: The above is a brief review of the studio's ZF Factory Portofino crown. I explained the use of the functions and also included 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 play with this watch and to take care of it. Let me share this much content today. I also invite all watch lovers here to discuss watch information. There is no end to learning per hour; You can only learn more subtleties by constantly improving yourself. Thank you for watching!
