Cartier has many OEMs all over the world, and the technological level of different manufacturers will be more or less different, which also leads to differences in details of the same watch because of different manufacturers, and these differences can not be used as a basis for judging authenticity. The first is the price. If you buy it in China, the cheapest Cartier watch will not be less than five digits. So if you are online or someone tells you that you can buy genuine Cartier blue balloons, you should pay attention when the price is only a few thousand dollars. They are all fake, without exception. Don't try with luck. What if it's true? You know, what you buy will never sell! Secondly, Cartier watches generally have 2-4 warranty cards (depending on the model of the watch), all of which are dark red and the same size as credit cards. The number of the watch (watch model, production serial number, movement number, seller's blue print) is printed on it, which corresponds to the watch one by one. The contents of the guarantee card: including international guarantee, proof of precision timepiece, natural diamond guarantee and watch function guarantee. And because all genuine serial numbers are one-to-one correspondence, it is often inconvenient to fake high imitation watches here. In this regard, look at a quasi! In addition, Cartier's blue balloons mostly use the "blue steel" pointer, and the baked blue pointer of genuine watches is dark blue and dark in color. The color of electroplating is very beautiful, the surface of the watch pointer is flat and smooth, and the color of the watch pointer is consistent with the color on the watch scale. On the other hand, imitation watches are often dull in color. And the handling of details is often difficult to reach a real height! Next, let's talk about the difference between genuine watches and imitation table fonts. The lettering fonts on genuine watches are clear and profound, and the strokes of the fonts are relatively thin. Although the handwriting is small, every letter is clear when you look carefully. In addition, the Cartier fonts on the back cover are thick and thin, while the letters on the replica table are often the same thickness. The letters in the real table are thin, and the strokes are thin at the turning point. The upper right stroke of the letter r ends in a circle. There are obvious strokes on the upper right of the letter C, and these details are often ignored by fake watches or lack of technical strength, which is impossible. Look at the comparison carefully and you can see it! Cartier watches also have original serial numbers, and each serial number is unique. It can usually be seen on the back cover of a watch, or on the back of one claw of the watch. This is an eight-digit number. If it is an automatic mechanical watch, the 8-digit production serial number will also appear on the edge of the movement splint, and the production serial number of the case is the same as that of the movement.
