I own a smartwatch which, for some odd reason has the glass sticking up slightly over the bezel. I've cracked one, and somehow, after 3 months, I'm getting a replacement. 

I'd like to prevent it from failing again. I'd love to post an image, but the manufacturer's been so nice, once I yelled at em proper-like so...

The last time the watch seemingly cracked from the edge, no drops, so I assume it was compression damage

That edge is fragile. What would be my option for protecting it?
