This unique Bergeon tool was designed to make it possible to open watch cases with ease. Just position the point of the tool between the case back and the case and push slowly. The blade will "pop" under the back, allowing you to lift the case back off. What makes this possible? A spring and firing-pin mechanism inside, you can open watch case backs with just a turn of the handle. The strength of the firing pin can be adjusted by screwing (more power) or unscrewing (less power) the handle. Set comes with two different tips allowing you open a wide variety of snap-on case backs.
