I have a musical watch that didn't cost much when purchased but has sentimental value. It takes 3 batteries, one to run the watch and 2 to play the music. I can get the watch to run but have trouble with the music part. Does one battery go up and one down, both down, or up? Also there is a small spring sticking up from the watch, in the middle of no where. Does this spring have anything to make the watch play music, sort of like a contact of some kind that needs to be in contact with the metal watch back? Any help anyone can give me would be greatly appreciated. I love this watch and would love it even more if music again played from it.
