Considering we don't even know what continent you're located on, it would be hard to recommend a specific person to authenticate your watch. But if you can post some better photos, including of the inside, you might get some help from the forum.

Hi, sorry about the late reply, I’ve attached pictures of the inside and I am based in London
Honestly, I have no doubt that your watch is legit. It's an early 70s model. The reference is the number inside the caseback, 511.342. These small gold-plated watches aren't terribly popular with collectors, so you may not find many examples on the internet.
If the bracelet doesn't have an Omega logo on it, it may be made by a third party.
As Dan noted, it's genuine and from about 1970.
The bracelet is not original, the case reference code "5" indicates a "Lady's Watch" and would originally have had a leather strap.
