Help with a possible counterfeit GMT Master II Black Dial

[SmeraPhantom]

Hello,

This is my first post and I would like to say thank you to all members.
My brother just purchased a Rolex GMT Master II Black Dial which I think is a very bad counterfeit copy. The bracelet makes a noisy rattle everytime and there are also other signs of very bad finish in the bezel which raised some concerns. There are no clicking sounds when the bezel is turned and the numerals seems not sharp. The bracelet shows a very bad stamped Rolex crown in the clasp itself. Also, the shapphire crystal glass seems to raised for this model. I sharp and expert eye would be greatly appreciated. Best Regards, Roberto.
