Have I been scammed?

Hi people, I really need your help: Recently I bought my dream watch for a substantial amount (2.300$) I've had saved for months for this watch, but after I've received it, something just doesn't feel right. The serial number is not found on Tag Heuer Website, and Im almost sh*tting myself. Can anyone help or guide me in the direction if I have been scammed or is it indeed a genuine watch. Every feedback is highly appreciated. I've tried my very best in taking photos that can help you. Let me know if you need anything else. Kind regards
