Step 1

First, you need to open the watch case and remove all the important parts of the movement to avoid damaging them. Now that you have removed the inner workings of the watch, all that should be left is that watch case and the old crystal.

If there are any embellishments on the watch case like gemstones or colorful painting or antiquing, DO NOT place the watch in the chemicals.

Start by filling your chemical resistant container with enough Attack liquid to completely submerge the watch crystal.
