Unless the watch back has notches on it, you want to look around the edge of the watch and find a little lip. When you find the lipp, use one of the knives and pry open the back. Take one of the tweezers and pull out the battery, you could also use one of those handy-dandy screwdrivers to pry out the battery. Put the new battery in laying exactly like the old one , then proceed to close the back, making sure that the little notch (on the INSIDE lip of the back case) lines up with the stem and crown (the part used for setting the watch) so not to break it. The back openers and the knives are just differant ways to opn the back of the watch. Sometimes watches have screws on the back that need to be taken off in order to open the back case. The case vise is to minumize the wear and tear on your hands. The tweezers are for taking out the battery. If you have anymore questions PLEASE feel free to contact me I will be glad to assist you further! Good Luck!!!

SOURCE: The plastic piece that keeps

mcdevito75 here, This is a piece of plastic is used betwen the battery and the back cover of the watch as without the plastic there is a small gap between the battery and the back cover, meaning the battery could come loose in the watch even with the back cover on the watch, replace this plastic piece with some carefully folded Scotch Tape, cut and shape the Scotch tape to Approx. the same size and thicknesss of this piece of plastic or just by sight thick enough to keep the battery in place in the watch with the back cover on.
