Generally, the most easily exposed fake Lange watch is the LOGO, especially the LOGO on the surface. You can watch the workmanship carefully with 4x eyepieces. If it is a metal LOGO, the true watch is generally as bright as new, and the edges of the fake watch LOGO are rough, and there are some irregularities. There are shades, you can see more clearly with 8x eyepieces. (Usually LONGINES, Hundreds, OMEGA, ROLEX and other watches are copied more)
Two. Table mirror
Lange watches generally use sapphire crystals. With the advancement of technology, fake watches have begun to follow suit.
Sapphire mirrors for fake watches are generally easy to see, because fake watches will not be coated with anti-reflection layers on the mirrors, let alone double-layer coatings, so they reflect badly under light. It only needs to be irradiated with ultraviolet light, and the reflection is extremely serious; since the real watch has an anti-reflection coating, there is not much reflection under strong light, and it has purple or blue glare.
3. Put your head
In general, the handle of a fake Lange watch is the easiest to reveal. The handle of the fake watch will use the same process. The polished and plated parts are not uniform. Whether it is plated or gold-plated, there are always differences in shades. If you look closely, you can also see the exposed part. If the case that is relatively real is not easy to detect, you can carefully observe the head part. In addition, the handles of many famous watches have their own specifications, and fake watches are almost the same. This can be easily seen by just looking at the appearance of the real watch.
4. Back cover
The back cover of the fake Lange watch is not made according to the preparation of the famous watch. For example, the original screw cap is made into a gland. Friends who are interested may wish to pay attention to it. Some watch back covers are octagonal or several screw back covers. In order to save costs, fake watches will make unremarkable screw cap-shaped glands.
Literally you can easily find handwritten traces with an 8x eyepiece.
The Lange watch factory has its own fixed numbering rules, and has its own serial number. According to this number, you can find the specifications of the watch, even the date of manufacture and the place of sale, while the fake watch only uses a number, and even Since there is no number, it is easy to distinguish.
The numbers of some true watches appear in different places on the watch, but the fake ones only appear on the back cover of the watch.
The workmanship of the bracelet can clearly see that the traces of handwork must be imitation watches. Although some fake butterfly straps of butterfly buckles are relatively delicate, they have rough and unpolished details at the corners of the activities. You can find them by carefully flaw.
Observe the fake Lange hands carefully with eyepieces, you can find tiny traces, which are the tweezers marks left during installation, the real watch will not see similar traces at all.
The shape of the hand is obviously different from the real watch. Even if I have seen the real J watch, the second hand can see the problem. The fake second watch is rough and short. This is the biggest problem. The real watch is general. The second hand is longer than or equal to the length of the minute hand.
Sound: Except for fake watches such as the Swiss movements, such as 2824, 2836, the other movements have a frequency of 21600. You only need to pick it up in your ear to hear it, almost all of which are slower ticking sounds. The watches are all above 28800 frequency, but many real watches also have slow swings, so this is just one of them.
Grinding: There is no need to talk about it. Generally, fake watches are not polished. But now there are many fake movements on the market that are polished, but the roughness of processing can be easily found with an eyepiece.
Structure: (Each watch movement has its own different structure, instead of ETA’s 2824 can be imitated)
