Authentic Check on a Rolex Gmt II please help

[jordanxi]

Hi guys,

I'm a novice so I wanted to seek advice on this rolex gmt II. Is the watch authentic or not? I know the pictures are not great but its what the person gave me. He has the original box and papers, even a paper from a third party appraisal. However, a few things throw me off such as the scratch on the reference numbers and bracelet. I thought there was suppose to be writing on the bracelet, also are the scratches on the lug trying to hide something? Please help if you have any information.

Thanks
