If you do not want to get frustrated and curse a blue streak, and you plan on changing watch bands, get this tool. This is the easiest and slickest tool, for changing out those little spring-loaded devices (looks like a mini-metal version of a toilet paper holder spring-loaded bar) that hold a watch band in place. My friend Lily has lots of watches. Most of them, she hadn't used in decades because the bands broke, or they were missing bands altogether. I bought this little gizmo and she is yippee-skippy about all of her "new" watches that she can wear again. She even had an abalone covered stretchy metal band, which never had a watch face, so we did a little mix and match with her other watches and she is thrilled to be wearing it. She had that abalone band for over twenty years and never attached a watch face to it, so it just sat and sat in her jewelry box, looking sad and pathetic. Now it brings a huge smile to her face. Two seconds with this device and presto...she has about 20 newly repaired watches to choose from!
