Removing a watch back can be an exercise in frustration. You want to open the thing up to replace the battery or clean it, but you don’t want to scratch the crap out of your precious time piece. Sure, you can get a tool on ebay, or from some other place, but it’s still risky. Enter the “Watch Case Ball”. Designed to remove a standard screw on back, it grips the back firmly, and won’t scratch due to the soft material it’s made from. At $5.00, it’s quite the deal as well.
