Omega 2505-6 - Unfamiliar dial, authentic or redial?

Hi everyone,
I’m looking for some quick advice on a vintage Omega 2505-6 I recently found. I haven’t come across another example with this exact dial, so I’m unsure if it’s original or possibly a redial. The printing and overall layout look a bit unusual to me, but I’d really appreciate more experienced opinions. Are there known dial variations for this reference that might match this? Also, assuming average condition, what would be a rough value range depending on originality?

Thanks guys! That’s what I was thinking as well.
