Rubber Screwball 'HORB' Case Back Opener.

You may never need to use another screw back case opener again!

This revolutionary product has been warmly received by everyone within the watch repair industry. It removes all the worry of the tool slipping and marking case backs. There is not set up time or aligning of holes!

The hand help ball is easily used just by applying to the case back, removing the air by squeezing with finger and thumb and then just turning!

 ** Please NOTE - Not all case backs will be removed with this rubber screwball, especially ones that have not been removed for a long period of time or if they have been previously over tightened.  You may still need to use a more robust screw back case opener for stubborn hard to turn backs**
