BERGEON 8008 Rubber Ball Case Back Opener

The BERGEON 8008 is a professional Swiss-made rubber ball case back opener designed for safely opening and closing screw-down watch case backs without scratching or damaging the watch.

Made from high-grip rubber, the 8008 creates a large contact area against the case back, allowing users to apply friction and torque to loosen or tighten threaded case backs. Unlike traditional metal case opening tools, the rubber ball significantly reduces the risk of slips, scratches, and tool marks on the watch case. 

Its simple yet highly effective design has made it a favorite among professional watchmakers, collectors, and hobbyists for routine battery replacement, movement servicing, and waterproof gasket maintenance.
