1. Look at the needle shaft: the genuine needle shaft has fine workmanship, the bottom surface is round, the white part (shaft sleeve) protrudes obviously, and it has chamfering work. The imitation technology is far from this, the bottom surface is not round, and the paint leaks locally.
2. Look at the crown: the crown part of the genuine crown is extremely fine in workmanship, the head and teeth are polished, and the bowl part has a high finish, which is mirror polished. Although the imitation works well on the head and teeth, the polishing of the bowl is uneven.
3. Look at the screw holes in the back cover: genuine screw holes are round, with chamfered edges and almost no machining marks. The imitation screw hole is obviously not round, and the edge cutting burr is obvious, and there is no chamfering work, and the machining trace is slightly serious.
4. Look at the case code: original Cartier watches, especially men's watches, should be printed with many English letters on the back cover of the case, indicating the name of Cartier watch, the country of production, the name of all-steel or semi-steel waterproof, antimagnetic, shockproof or shockproof device, and engraved with the trademark pattern dedicated to Cartier watch brand.
5. Look at the dial of the watch: Some counterfeit Cartier watches with daily and weekly calendars have the following characteristics: when viewed from the calendar window, the outside of the calendar dial is tilted backward, or the calendar dial is made of plastic.
I hope the above information can help you identify the blue balloon of Cartier watch. For more information, it is recommended to consult a professional appraisal institution or person.
