Have you noticed the pip at 12 has no protection to cover the lume? I haven’t scraped mine yet but I think this a big a flaw of the ceramic bezel. They added ceramic to make more reliable than the standard aluminum but at the same time made it more fragil...  

... since it is a rather large area, chances of damages are high. However, there must be some kind of protection from ageing, so I assume the binding agent used is hard enough to withstand shocks. And the sapphire lenses often used to protect the illumina... 

I just expected ceramic bezel insert to have the triangle recessed and protected

...  

That portion is just raw lume or whatever composition makes it. I guess no big deal I was just a little shocked that they would do that.
