The screen size is the same on the 5 and 5X and I wanted a screen protector for my Slate Gray 5... I assume a 5X screen protector will work so I ordered this from Amazon. I don't see any tempered glass one for the 5 yet so I ordered the 5X version assuming it will fit..

It will be here tomorrow and I'll report back on if it fits...
I am pretty anti screen protector on a watch and usually buy sapphire versions of the watch. In this case however, I like the Slate Gray look -v- the black 5 sapphire.. I am hoping it fits and I am hoping it's basically invisible once installed...
