You should have bought it online. If you buy it in a regular shopping mall, you won't know where the security code is. The following is some information I found for you. I hope it helps you.

. 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.

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 are all rough, and there is 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 a timepiece for a few hundred dollars, it must be a fake watch.

Therefore, to buy brand-name watches, you still have to go to a larger regular store or specialty store to buy genuine products in person, so that the quality and after-sales can be guaranteed. If you still can't judge, I suggest you take it to the watch shop and ask the master to check it for you, so you can see the truth soon.
