Watch Crew: What to buy?

Any way to check if something is real or fake? I got one from NYC for cheap and curious if its a knock off or stolen. Can I just bring it to a jeweler and ask them to take a look?

Its an automatic Panerai Luminor Marina 44 mm with the metal band. Its got the clear back so you can see the self winding that is branded with Panerai and everything. Pretty elaborate and solid for a cheap knock off so pretty curious.

It is a fake. Found 2 things that are missing tho.
