I can't see the picture of your watch, and you didn't explain the model of your watch. I can only guess that there are two possibilities: If your watch is a light kinetic energy radio wave watch, the BAND CHINA on the strap may mean that the watch receives radio waves in the time zone of China, or it may mean that the strap is made in China (Hongkong). But these two points alone can't judge whether it is true or not, and I don't know whether the duty-free shop is true or not. I have told netizens many times that Citizen has not set up factories overseas, including China, but only outsourced some parts (such as watchbands and watchcases). In addition, Citizen's watches have a high technical content, and the possibility of counterfeiting is not great, only parallel imports are possible. Did you bring a sales guarantee or warranty card when you bought it? Tell me the model and purchase price of your watch and the name of the specific place of purchase.

Supplementary answer: Is your watch barrel-shaped? I can't find your model. I'm afraid they are sold overseas except China. Can you send me a photo? Models sold overseas will be changed when they arrive in China. Besides, it doesn't matter whether it is parallel imports or not. The quality of parallel imports can be guaranteed.
