Removes and inserts crystals without disassembling the watch. Effortlessly remove and insert any round unbreakable crystal without taking the watch apart or removing the bezel. Eliminates all rings, wrenches or

pliers and the brass fingers will not mar the crystal. The gripping force can never lose strength because the fingers are mechanically operated. Access to the dial and hands is instantaneous and the works of one

piece cases can be laid bare in seconds. A platform is provided to grip a new crystal for inserting into the watch. 8 to 45 mm (3 3/4" - 20 linge)
