I think the printing at the bottom was more of a market-by-market approach at the time this watch would have been produced (~1940's). Later on, it became more standardized.
However, I would need an up close inspection, as the pictures are a little out of focus. A case reference number would be helpful as well. Nothing better than to Google up Omegas with the same case reference number, looking for those with the same dial. Doesn't always work, but worth a try.
Hope this helps,
