Rolex Buckle Real or Fake?

[bonvivant]

Hello Everyone,

I am very new to this forum and in need of some of your expert advice. I have a 1970 Air King and recently purchased a lizard band without a buckle.
In my frequent searches on eBay I came across the buckle shown below. It is described as a vintage genuine Rolex ss buckle that has been polished. What are your thoughts? Real or fake? Thank you so much for any help you can offer.
