Your additional photos are very tiny, and I can't view any detail on them.

I hate to say it, but it's not a minor issue that makes me doubt the watch.. it's everything.
The dial, the bezel, the hands, the case, everything is wrong - I'm really sorry, but I'd guess that the entire watch is a fake.
The bezel looks like it's from a Wittnauer chrono, and maybe the case. From what I can see of the Heuer shield, I'd say it's very 'un-Heuer-like' and not genuine either.

Again, I'm really sorry.

: The watch was bought in a serious dealer store in Brussels.
