Hi there, could anyone give me any info on this watch.

Many thanks in advance.

 

I agree, rather a common fake/counterfeit.

For confirmation refer to numerous other examples here

Worthless then.

 

Yes. It is a fake and holds nothing but potential sentimental value.
"Autobahn Gold" it was called. The case is 99.9% not gold either (even if stamped like it). In fact Omega never made such marks on the outside of a watchcase (only inside of the case back).
Take it to a jeweler if you like to have the metal checked for gold content but I assume it is very near nothing.
