very poor instructions. It's screen protector as actually three layers he back layer the screen protector and a top layer which is used to apply the screen protector. You peel off the back player and then use the tab to align the screen protector on your watch face. Then rub vigorously to apply the screen protector to your watch face. Then pull up on the tab which will leave the screen protector behind. I actually ended up with two screen protectors on my watch face. I tried the first one and didn't realize that the top layer was actually an application I then tried again and ended up with two screen protectors attached to my watch face.
