Magic Pocket watch

*You sit in your room staring at your watch when you notice a small button, you decide to press it and suddenly your cracked phone glows then starts to float in the air. you spin the hands of the watch back one day and your phone looks how it did a year ago. now you know why your grandpa only gave you this watch because if you move the hands back one day then the thing you selected will go back a year in time*
