Hello, this Rolex is obviously a fake watch. Rolex watches have gold, but that's stainless steel and gold. The clasp of your watch says 18k. How can the obvious steel part be used with 18k gold? In addition, Rolex is only made of pure gold instead of gold plating. Your gold color has faded in some places, so you will know whether it is true or not. In addition, if you really buy it from Japan, you can make a lot of money by keeping the store's receipt. Japan is still cracking down on counterfeit goods. I hope my answer can help you.
