This Swiss made Chronograph Tube Tool is made to screw in and remove the threaded portion of a watch push button in watch cases. The tool has tiny knurls that fit over the tube the same way the Rolex case back openers fit over the back of a Rolex watch, allowing you to get the maximum amount of leverage with a minimum amount of force. You can then turn the tube while inserting or removing the case tube without once damaging the tube or the threads. And because of the unique knurled grip, the tool will not slip while you are trying to loosen or tighten the case tubes and mar the surface.
