LYECUNLYECUN Watch Case Opener Ball, Watch Friction Ball Will Not Scratch the Watch Back Cover, Watch Battery Replacement Tool

I work on vintage watches to sell on eBay, and this works on most of the screw-on type case-backs I run across that aren’t frozen from years of neglect (or degradated caseback rubber seal). Prevents scratches entirely. Good size, not overly bulky. Quality seems as good as the more-expensive Bergeron ones. Recommended!

Muy buena opción para no lastimar los relojes, cuando se cambian las baterías.

I have several battery powered watches that need battery replacement about once a year. I've been using a watch back removal tool, but didn't like the scratches and marks left behind after each use. I saw an online video showing a watch repair person using the rubber ball method and decided to give it a try. It worked amazingly well on all of my watches. I'm so glad I saw that video and purchased the Lyecun watch case opener ball.

Watch repair.

I tried and tried to get this to work. It's just wasn't "sticky" enough to do anything. I couldn't open watch backs or even get them to screw back on. I tried more and less air in the ball. Honestly using my fingers was much more effective than the ball. I ended up using one of the 2 prong metal tools sold on Amazon to remove and tighten my watch backs. I think this product is useless, especially for water resistant watches that need the back to be snuggly attached. Save your money.
