I was under the impression they were black ion plated bezels per what I read on some of the grey market dealers sites. Ive read the Oris.ch web page and it says ceramic but it doesn't look like it when I directly compare the SS aquis ceramic bezel and a titan ceramic bezel. the bezel on the SS model is much smoother and what you would normally see with ceramics.The Aquis Titan Small Seconds comes in DLC with a black ceramic bezel, plain Ti with a black ceramic bezel or plain Ti with a tungsten bezel. If you want another colour bezel or hands you will need to go for the steel Aquis range which also have tungsten or ceramic bezels.
Ceramic can be either. The ceramic bezel on my Aquis Maldives is matte, but the ceramic bezel on my Submariner 116610 has a glass-like polish to it.I would assume a ceramic bezel would be matt and a tungsten shiny but that's a complete assumption with no background knowledge.
