This one looks to be the First Lady 'F' in white gold. I find ads for the 'E' and one NOS example with tag calling the white version the 'F'. There were other First Lady models using these variants, and all call for yellow as E and white as F. Based on all of this, I would be okay calling this the 'F' variant.
Band on yours does look to be original.
