Rolex 16520 WG Bezel?

[St-Maxime]

I got this bezel years ago when I was looking for steel but ended up with what must be white gold.

I believe this to be a gen Rolex bezel but I can't find any info on it online. There's a YG bezel that looks the same but no WG. The WG always shows the more recent design with the triangles.

Any thoughts?

I have a book on the 16520 I can check in a few weeks
