1910's Omega 0.900 case

Hi!

I recently acquired I small lot of vintage timepieces and one of them was a Omega from the early 20th century which I couldn't identify.

It's a 32mm 0.900 silver case but shows some signs of pitting and is in a very yellowish hue which I can't really place. It has an enamel dial and fancy lug design which I'm not sure if these where added at a later point.

Does anyone have seen this case design before? And a silver case with yellowish tone? Thank you in advance!

Looks like it was gold plated once.

Well if it was it should have gold plated markings somewhere

Depends on who plated it. Local jeweler? Doubt it.

If its aftermarket it won't but thats why I'd like to find out if the lugs are original to the watch.

It appears to be Omega but that case is a disaster so I would run screaming unless you think you can source a case somewhere.
