The battery in my skull candy bully mp3 watch has gone. I believe that there are two batteries, a lithium ion rechargable battery, and a normal watch battery. If this is true, both are dead. The rechargeable battery only holds a charge for a few seconds. I have taken the watch to a store to replace the batteries, however when they look inside the watch, they do not know what to do with it. Also, we cannot get the back to close again after having the store open it. Any assistance would be much appreciative as the skullcandy company has not been of much assistance. This is my favorite watch, and I don't want to have to buy a new one. Please help. Thank you!
