A:AnswerYes, I have this screen protector on my Samsung Gear 2 Classic Smart Watch. You want to ensure you center it as close as possible since the protector is little smaller the watch screen's surface area.
A:AnswerI have the Verizon 3G classic and it fits but there is a small gap around the screen. If you center it the best you can it's not horrible I just thought it'd be like the phone ones that go from edge to edge.
A:AnswerNo. It actually is a great protective screen saver. Saves my watch from scratches and knocks. It is a film and not tempered glass but very protective.
