Tap and Die
These tap and die sets and kits are great watch repair tools for watchmakers to have around their workbench. When a watch comes in for repair and the watch back screw threads are so stripped you can barely use them, you can use a screwplate to re thread the screw and extend the life of the watch. These taps and dies are handy for other types of watch repair as well, all you need are the right watch tools.
