If I was guessing I would say 99% of these watches are using plastic chapter rings. I've been inside enough Android and Invicta models. I was a little surprised myself early on to see what I thought was steel being lightweight molded colored plastic having a textured finish.Yes, like that, with a better bezel. The bezel above is like a plain bezel with painted numerals.
Also a plastic chapter ring
The regeneron has a sand textured ring on the dial which I'm liking.
