Looking for a domed bezel insert for SKX

[tic]

So far I haven't had any luck in tracking down readily available (acrylic? ceramic?) domed inserts for Seiko SKX bezel.
Vintage Seamaster style would be great, but other designs might do, as well.
Any tips or suggestions?
(Here's a borrowed pic for reference.)

Something like this?

Well, yeah. That might have contributed to the idea...
But before asking the 'mod god' for a custom piece, I thought I'd check if similar stock parts exist.

Not sure. But Athaya makes them too.
