Hublot Geneva Ayrton Senna. Fake or Original? Plz Help

Hi, this is my first post to the forum.

I got this Watch from my father, but i can't define if it is fake or not.
I took it to a "Specialist", but he couldn't say so.

After searching, i found this forum.

I would to know if it is fake or original, and its estimate price.

Photos were taken with my iPhone, and are hosted on imgur
