Got a new tool!
This one is used basically for pressing stuff. Well things that are bigger than jewels. It has fine control, but not as fine as the jewel press. It can press crystals into place, case backs can be snapped on, and it has accessories to press pins out of bracelets accurately, and a case back knife (but I have a tool for that already too)
This one weighs 3.4 KG, and I also picked up a die set for crystal presses. Here I am practicing on an original crystal that will be replaced. You can see how it bends the crystal all around, allowing it to snap into the bezel (you can even hear it snap in). Then when pressure is released, it expands to fit snugly.
