Is this buckle real or a fake?

Hi all, new to this site and in need of help. This buckle was sold to me as c.1965 Genuine Rolex gold plated buckle.

Apart from the Rolex Crown, there are no markings on the buckle at all. I queried the seller over this and his response was "Many Rolex buckles produced from the 1940's-1960's were subcontracted with Rolex's full approval and sold through Rolex outlets and there are thus an array of differing markings and plenty were sold without markings underneath"

I also note the eyelet pin is drilled and not rolled as with every other Rolex buckle I have seen.

I would appreciate any credible information you can offer me either way.

Sorry for the poor quality images.

Many thanks
