Hi, Wanted to see what the pros here can teach me. I'm trying to get better at spotting real vs. "questionable" Heuers, so can a Regatta expert take a look at this example? First off, I see a caseback with a different metallic color than the case, and secondly (in one of the enlarged sideview pictures) I think I see a Rolex crown! Am I seeing things? The model number seems correct given the nickel colored dial (vs. black/silver). Is this Regatta (other than the crown) the real deal?

Trying to learn.

Thanks.
