I have a Samsung watch4 classic 42mm with case and charger. Has had a screen protector on it since new. It's LTE, Bluetooth, Wi-fi, and GPS. Classic version has the spinning bezel which also helps protect the screen Works great just got a new one as a gift so no longer need this one. The back side looks like its really scratched in the picture but it's not that bad in person does not affect function of watch at all just from normal wear and tear
