Polerouter Sub Bezels

Hi everyone,
I am currently fairly interested in UG Polerouter Subs. What I noticed, though, is that there seems to be a large number of different bezels, some of which seem a bit strange.

Notice how the inlays look like they have been cut off on the outer rim to fit the bezel, while the inner rim seems to have more or less the right size. Has anyone noticed this before? Does anyone have an explanation for this? Could it be that inlays for later asymmetric cases have been used to replace inlays on earlier symmetric cases but had to be machined for fit on a slimmer bezel? Here an example from polerouter.com with an asymmetric case but fitting bezel inlay.

What do you folks think?

Is it not just where the black coating / paint has been worn away over time with all 'turning' of the bezel ?

I may be completely wrong with this assumption and happy to be corrected

Just worn.

variations are 10-20-30 and so on or 50-40-30 and so forth.

both are correct.

dot may should be a shinny orange but is often different. Probably due to adventurous owners!

Thanks for your replies guys. 👍
I guess they are correct then.

P.S. Someone else got the one from Knightsbridge ahead of me. If he or she is around here - congrats and enjoy it 😉
