Was 5 stars review until the watch stopped telling time, but still lights up. When I decided to change the battery, which I assumed would get it working properly again. I tried prying the watch open at the designated slot with precision screwdriver with no luck. So I lightly tapped the end of the screwdriver, I was using with the handle of another screwdriver too hopefully looisen the seal enough for it open, Not only could I not get the battery cover off, but several numbers and design accents fell off as well! Not worth $60 for one battery use!!! Unless you just want an expensive prop!!!!
