What Omega sold for $3 million?

Excuse me, could you please clarify which Omega you're referring to? There are many Omega products ranging from watches to financial products, and it's not immediately clear which one sold for $3 million. Was it a unique, limited edition watch? Or perhaps an investment opportunity in the Omega brand that fetched such a high price? I'd be happy to provide more information or context if you could give me a bit more detail about the specific Omega in question.
