In the world of cars we'd call it a "ten footer"...meaning it looks good at ten feet but as you get closer things start to fall apart. I won't repeat what others have already said. It would be worth taking it to a watchmaker who is an expert in Omegas, and have the watch inspected inside to see what else might be wrong. They could correct the wrong crown issue for you right away. The broader issue is, can you get your money back. If not, enjoy it at ten feet and move on. If you, as you learn more, you find a correct dial (in any color) you might consider replacing the black dial and keeping the black dial for some future use.
