Authenticity Question Before Purchase - Submariner

[violin321]

I'm selling a car, and a buyer offered a trade for a Rolex Submariner that was inherited from a grandfather. I've done my best homework via the forum to try and authenticate myself, but my results are inconclusive. Would appreciate the input from someone more experienced than I. What do you think? Real or fake?

Based on my forum research, there are a couple of red flags: 1) The hologram sticker has the Rolex logo on it--and I read that it didn't appear on the sticker until after 2002. 2) On the outside of the bracelet, just above the Rolex logo, the spot where you pull to unclasp the bracelet looks different (deep, square) compared to others I've seen.

I'm aware that one of the links on the bracelet is broken.

Thanks for the help.
