PRODUCT FEATURES
Professional watch case opener designed in the shape of a soft rubber ball, combining functionality with a simple, user-friendly design.
Rubber construction provides strong friction while protecting the watch case from scratches or damage.
Ideal for opening screw-back watch cases safely and efficiently.
Easy to use—secure the watch on a holder or hold it firmly, press the ball against the case back, and rotate in the opening direction.
Requires inflation before use. Inflate to about half capacity for best grip and control.
For extremely tight case backs, it is recommended to loosen first with a wrench-type opener before using the ball.
IMPORTANT NOTES
Do not pry open the watch case directly with force.
Over-inflating the ball may reduce grip effectiveness.
