It's always a crapshoot buying from Latin America, but there is just enough good stuff to keep us compulsive gamblers in the game. FWIW, I think that dial is legit. My bigger concern is the condition of the case. I don't know what that particular case reference should look like and I can't decide if those lugs have been savagely overpolished or only milldy polished. I don't think that question is answerable unless you ante up the money that will allow you to inspect it personally. And don't count on a generous return policy from most Latin American sellers, or if there is, a terribly scrupulous postal service. So, as the great philosopher Dirty Harry would put it - "Do you feel lucky?"
