It depends by how you define 'pass as gen'.
If you mean people here might want people to appreciate that they are wearing a nice watch, yes, it's always nice to receive compliments, but mostly, folks just don't notice, or if they do, rarely pass comment
If you mean people would actually say "Yeah, it's real..." if asked if it's real or fake, and it's really a rep, then you won't find many like that on this forum
PS For your size wrist, I would suggest a Panerai 127 or 217
