How to check watch case back cover?
Observe the back cover of the case. All original watches, especially men’s watches, have many English letters printed on the back of the case. Indicate the name of the watch brand, the country of manufacture, and the name of the all-steel or semi-steel waterproof, antimagnetic, shockproof or shockproof device. It is also engraved with a special trademark pattern for the watch brand. In addition, some numbers are also engraved to indicate the movement number and case number of the watch.
Most of the patterns and letters engraved on the back cover of counterfeit watches are thick and fuzzy. Unknown shell number and movement number. The back cover of the original watch usually has an adhesive film affixed to it, while a green plum blossom-shaped label is affixed to the back cover of the Tortoise watch. For Swiss-made gold-plated watches, letters are engraved at the opening position of the case and the spring bar on which the strap is installed, such as PLAQUEGI0, indicating that the case is 10 micron gold-plated. Counterfeit watches do not have this mark. Many counterfeit watches use techniques such as titanium nitride to impersonate the gold-plated case.
Observe the crown head. The trademark or letter imprints of counterfeit watches are thick and fuzzy or printed with 100% W~P, and all-steel watches use half-steel handles.
