1, look at the movement:

The genuine international watch movement is clean inside, while the counterfeit international watch movement is not clean inside, and there will be fingerprints, hair and even copper pieces. The movement is very stable in the components of the case. Genuine iwc watch movements will have clearly corresponding trademark words on thallium or inner film, while counterfeit watches will not have trademark words on thallium or inner film, and some will be rough and illegible.

2, look at the appearance:

The trademarks and handwriting on the dial and back cover of genuine iwc watches are clear and complete, while the trademarks on the dial and back cover of counterfeit watches are blurred. The number of diamonds on the genuine watch and the movement will be consistent with the numbers marked on the dial, while the number of diamonds displayed on the dial of the counterfeit watch is not consistent with the number of diamonds on the movement.

The material and case of genuine iwc watch are the same as those marked on the back cover of the watch. The glass on the watch is clear and bright, the edges and corners of the case assembly will not feel sharp, and the coating will not fall off without bubbles, while the counterfeit watch has rough edges and corners, the coating will bubble off and the accessories will break.

3. Look at the watch glass:

The glass of universal watches is sapphire crystal glass. The easiest way to tell is to tap the glass surface with your finger, and the real sapphire watch will make a crisp sound. It is not accurate to detect sapphire glass only by water drops.

4, look at the digital number recognition:

Carefully observe all the signs related to numbers on the bottom cover of the watch. False tables are usually irregular and even do not correspond to the numbers of real tables. Real watches are numbered independently.

5. Change the label after reading:

Depending on the factory label on the bottom of the watch, there is usually a brand logo on the label of the watch, as well as the model identification of the watch. Some watches have laser anti-counterfeiting labels on the bottom.

6. Look at that subtle look:

Universal watches must first carefully observe the appearance of the watch, including the polishing of the appearance. See if the polishing technology of watches is exquisite. The polishing of famous watches is very particular, but the technology of fake watches is far from perfect. Look at the font, the real watch is full of fonts, and the fake watch seems to lack confidence. Looking at the function, most fake watches will not work hard on the function, which is the breakthrough to see through the fake watch.

Look at the pointer, the genuine pointer can distinguish the authenticity from the length, thickness, shape and material. Looking at the disk surface, the common disk surface technologies of advanced watches include enamel surface, carving technology, metal cooling disk surface, shell disk surface and so on. Diamonds and inlay technology: Look at the inlay technology, the quality and size of diamonds.

7. Look at the watch box and certificate:

The value of a watch can also be seen from its case. The more advanced a watch is, the more elegant its case is. The model of the watch and the first unique serial number will be on its certificate, which is called "birth paper". Some brands of watch certificates will also use pinhole drilling technology to print the serial number and model of the watch on the certificate to prevent forgery.
