I don't see anything particularly suspicious, though I don't know much about bracelets of that era. Its just a normal lowish-end watch of the era to me, with a worn crown. Its unfortunately gold-filled which makes its current value significantly less, but runs on an honest, albeit cheaply done (for Omega) 1480 movement.
I see what you mean about the bracelet logo being a little heavy of a stamp. Though, it DOES look like a logo Omega has used on other watches in the past, so I'd not be surprised if either it is a swap, or just a number of bracelet SKUs were shipped with this watch.
There are a lot of strange things going on here. A case that is in seemingly good condition but a worn the hell out crown. The bracelet fit into the case is WAY off. A clasp from Omega that says "Stainless Steel Hinge"????? Everything screams wrong here to me.
