You will find an arrow head on the outside back of your watch where all the printing is. When you put this lid back on, this arrow needs to be aligned with a notch on the inside edge where the cover goes on. As you are looking at the watch from the back with the cover off this notch is in a northwesterly direction. If you doubt it then just hold the back on without popping it in all the way and hit your mode button to make sure that you hear the beeps again. If you do, then you've found the right spot.
