A scratch-brush is essential for cleaning the contacts. 1 all-plastic tweezers: metal tweezers can short-circuit the battery and reduce its life. That is why you should use plastic tweezers. 1 watch bar remover: one side is the 'prongs' for removing spring bars. The other side is a fine point for pushing them out in watches where there is a hole in the watch lug, for pushing the spring bar out.  1 needle-point tweezers: very fine, the only way to position those tiny screws 3 screwdrivers
