About Opal Dial Rolex Day-Date Authenticity

[ufxd2008]

Hi everyone,

I recently watched this video YouTube Video where Jasper from Amsterdam Vintage Watches commented on the authenticity of opal dials in auctions, specifically referring to the opal dial Rolex Day-Date from Phillips and Christie's . He mentioned that the opal dials in these auctions might not be authentic.
I'm curious to hear what everyone thinks about this. Has anyone come across similar concerns or information regarding these pieces?

Thanks!
