Can you use old phone cases?

@Onasander the smartwatch has amoled display

@ShiningGundam99 I low crawl in abandoned mines, caves and through briar patches sometimes. I expect a certain about of abrasion. I don't even take my phone when I do that (broke a flip phone doing that in the Army). Biggest problem is heat when it fades grey and won't display. I used it last winter but this winter I'll be sleeping outside, even if a polar vortex hits, so I don't know how well it will do in long teem cold temperatures.

You have to get used to the concept that the male physique is tougher than the elements, and electronics are not. There will be a extreme where they break down and you do not. It will be dissapointing.

@Onasander ok anyway it is a rubber strap??
