Used for removing watch crystals from one-piece watch cases.
Instructions for use:
A one piece case designed watch can be opened only be removing the watch crystal with pressure.
Removing the crown and stem:
First pull out the crown as you do when you change the time. The stem is made in 2 parts that connect and can be pulled out (with special key included). Remove the half-stem and the crown with the key.
Using the pump:
Pull out the tube from the air pump completely. Press the plastic tip of the air pump against the watch case (or case tube). Hold the watch case tightly while placing your thumb lightly over the crystal and push firmly on the pump to "blow" the crystal out of the watch.
