One thing about the bracelet I'm suspicious about is where is the foldover clasp?! The pictures show the bracelet opened out as if it's a strap with a buckle. I'm no bracelet expert, but it does look like an Omega, as do those end links - it's just that the end links look too small.
For example, here's a picture of 20mm straight end links in a 20mm lug width (notice there is very little or no gap):
In the pics you posted, you can see quite a significant gap - hence my guess they are 20mm end pieces in a 22mm lug width watch.
Look up the end link number when you see the watch and find out its size and what it's from...
