1. technology. Real watches are exquisite in workmanship, tight and flexible in seams, smooth in corners and even and bright in electroplating. The text on the surface and back is clear. The fake is rough, and the joint rotation of the bracelet is not flexible enough.

2. packaging. The packaging of the real watch is exquisite, the watch box is beautiful, and there are beautifully made instructions or warranty cards inside; Fake watches have rough workmanship, blurred fonts and even no such packaging.

3. Source. The real watch has an official invoice, and the selling price will not be much different from the published price. If you can buy several hundred to several thousand yuan Cartier watches, it must be a fake watch.

If you still can't tell the authenticity of the watch, take it to the watch shop and let the master check the movement (the difference between true and false is mainly in the movement) to see what will happen soon.
