This is the non-sapphire, gorilla glass F6P. Used 2-1/2 years on the left. A new (refurb) unit on the right.. The slight wear on the bezel is expected, however I was noticing quite bit of anti-reflective coating degradation. I had some other issues with the watch, and Garmin sent me a replacement-refurbished model (like- isn't that so cool, garmin is a great company). The clarity of the screen of a new glass is soooo much better, and how I remember it when it was new. Definitely disappointed with the wear on the old glass.
I guess another reason to pony up the extra $$'s for a Sapphire. I'll get an Epix someday.
