Went to my first NAWCC(North American Watch & CLock Collectors) show recently and picked up a few cool tools. The most mindboggling simple, but very effective one is the green ball($8) pictured here. Slightly tacky feel to it, you press it against any screw-down case back and turn. I've yet to come across one that it couldn't get off and no scratched cases or backs. The other toys are (left) - spring bar bender $10, and (right)solid carbide jawed nippers $25. The nippers in particular are an absolute joy.
Oh, and that absolutely mint Pulsar jewelers mat for $5...got one for a friend too.
