Need to identify Omega skeleton watch and find out an approximate price.

It's a converted pocket watch/marriage watch with a fanciful skeletonised main plate on a cheap bracelet.
The case dates to about 1925 so the movement will be about the same.

The original watch never left the Omega factory looking like that.

As to value?
To a person who is looking for a watch and does basic research, it's worth nothing.

Put it on eBay starting at one dollar and it will find it's value.

You missed the sales attachment, but that is valueless to basically everyone. Other than the PT Barnum types, I wouldn't expect anyone to pay basically anything for that. In addition to the above, I'd guess the hands/engraving/fake-dial-thing to be VERY recent, as it looks like the crappy cast almost-metal indices.

Which, btw, makes me irrationally(rationally?) angry: HOW did they choose which index was Arabic and which were roman numerals? I see 12/6/1/9? Or is the glare confusing me on the 1?

Unfortunately, it has no real value, but you never know what someone will pay for it.
