It features a sturdy design that ensures a strong grip and a scratch-free experience while working on your valuable watches. The ball is complemented by an extra metal pump needle, which allows you to easily inflate and deflate the ball to your desired firmness. Easy to Use: The MMOBIEL Watch Case Opener Ball makes removing screw-down watch backs easier and safer than traditional tools. Simply hold the watch in one hand, pressing the ball against the back of the watch case. Apply pressure, and twist the ball in the counterclockwise direction to unscrew the case back. This hands-free repair tool offers excellent grip and control, minimizing the risk of scratching or damaging your watch. Important Tip: Ensure the ball is inflated to a semi-rigid state for optimal performance. Over-inflating may reduce the tool’s effectiveness. Compatibility & Adjustability: This tool is designed to fit comfortably in any watchmaker's hand. It is compatible with a variety of screw-back watch cases, making it ideal for most watches, including popular models from brands like Rolex, Omega, Seiko, and more. Its adjustable, inflatable nature makes it versatile and customizable to suit your repair needs. How to Use: Inflate the ball using the included pump needle until it reaches a semi-rigid state (not fully inflated). Place the watch securely in your hand with the back facing upwards. Apply the ball firmly against the watch back. Twist the ball counterclockwise to unscrew the watch back cover. The friction between the ball and the watch case should help you remove the cover without causing any damage. Once the case back is removed, you can proceed with the necessary repair or battery replacement. Helpful Tips: Clean the ball and watch back before use to ensure maximum friction and effectiveness. If the watch back is too tight, consider using a wrench-type opener before using the ball tool. If you encounter resistance, gently apply more pressure while twisting. However, avoid using excessive force to prevent damage.
