Rubber Watch Case Opener Ball – Screw-Down Backs | Wellstraps™

Open screw-down watch case backs with this practical rubber friction ball. Its grippy surface helps you turn compatible case backs without placing a metal opening tool directly against the watch. Compatibility Designed for screw-down watch case backs with a surface the ball can grip. Not suitable for snap-on or pry-open case backs. Tightly secured covers may require a suitable wrench-style case opener. Key Features Friction-based opening: Uses rubber grip to help loosen and turn screw-down case backs. Soft contact surface: Helps reduce direct contact between metal tools and the case back. Simple operation: Press against the case back and turn in the opening direction while keeping the watch secure. Compact design: Easy to store alongside your watch maintenance tools. Specifications Material: Rubber Color: Blue Type: Inflatable friction ball Use: Opening compatible screw-down watch case backs Before Use The ball requires inflation before first use. Inflate partially so it remains soft and flexible; do not fully inflate. Keep the ball and case back clean, secure the watch, and apply steady pressure while turning. If the cover does not move, use an appropriate case-opening tool rather than excessive force.
