Watch cases with Snap on back
Step 1
 
Place watch in the case holding vise. Clamp the watch in the case holding vise by opening the two halves of the block. Place watch in the middle and gently release or tighten the two halves, so that clamps will hold the watch firmly. If the watch band does not unbuckle or unclasp, separate the band by pressing down with a pointed tool to remove the spring loaded pin that connects the band to the clasp or watch.

Most case backs are snapped on and can be removed by inserting a blade of a knife into the appropriate notch of the case or case back and a twist the handle of the knife to pop off the case back. |
|
When no groove is provided, be sure a sharp knife is inserted into the narrow slot between the back and the case. Once the knife is firmly in the groove, a slight twist of the knife handle will pop off the back. |
