Don't know, how to say it in a way that doesn't harm your enthusiasm for your new toy. but... - I can see some more flaws. To be honest, I can't see anything, but flaws.... Case, crown, CG's, clasp, dial-printing, hands, date-font - everything looks a bit like a SUB - but that's all.
Sorry mate, but you asked... Hope, you didn't gave to much money for it.
It was the same with me, some years ago. I bought my first SUB and was really happy with it, until the moment, when I came to compare it with other reps and genuine ones. Suddenly I knew, I was scammed
No offense meant, believe me, I have a bad conscience by writing this. But I think the usual nice-watch-wear-it-in-good-health-blabla would be unfair...
Cheers and welcome aboard,
