The GS Watch Crystal Cement is great for keeping crystals in place. Simply apply a small bead around the bezel of the watch. Then insert the plastic or glass replacement crystal into the bezel. Dries clear and strong.
Notes on using the cement
Because the cement tends to keep flowing out of the applicator once it starts, here is a helpful hint. If you do not have time to place the cap wire into the precision applicator between uses, keep an empty, small bottle (like a spice bottle) in your work area, along with a small piece of sponge soaked in nail polish remover.
