This tool was designed to make adjusting watch bands easy instead of being a hassle. It is an essential tool for any watchmakers bench because it makes removing pins from metal link watch bands such an easy task. The pusher pin is made of hardened tool steel that won't scratch or mar the watch band. Simply place your watch band in the opening, line the pin pusher up with the link pin and twist the screw to gentle push the link pin out of the band.
