This BULLONGÈ S-FACTOR watch tool is a new take on the classic method of opening a screwback or waterproof watch. Using suction, this tool allows you to remove regular watch backs with ease, and waterproof watch backs once the back has been slightly loosened. The rubber tip will not scratch watch cases or crystals, making it the perfect way to remove watch backs safely. Simply place the watch tool above the watch back, press down and begin to twist. The twisting motion applies suction to case and unscrews the back allowing to you easily lift the back off the watch. This watch case opener set comes with key and 10 different dies, diameter: 16 - 19 - 23 - 26 - 29 - 33 - 39 - 44 - 49 and 54mm.
