How to Replace a Crystal in an Electronic Watch

• Replacing a crystal oscillator or watch crystal in an electronic watch requires concentration and skill in working with the small components of watches, although the process is easy to follow. Use either the same brand of watch crystal or a generic brand. A different brand of watch crystal will not negatively affect the watch's performance as long as the new crystal is the same material and size as the previous crystal. Remove the back of the electronic watch, remove the old watch crystal, clean the watch case using a polishing cloth, and use a watch crystal press or epoxy to install the new watch crystal

Instructions:

• Remove the back of the watch using a master case opener, a Swiss case knife or a screwdriver depending on whether the back of the watch is a screw-in, a pressure fit, or is held in place by screws. The bezels of some watches hold the crystal in place with the bezel held into the body of the watch with screws
• Use a crystal lift to remove the tension ring or crystal gasket that holds the watch crystal. If the watch contains an epoxy that holds the crystal in place on the bezel, then use methylene chloride to melt the epoxy. Remove the watch movement from the case
• Use a polishing cloth to clean the case and to remove any debris from the area that held the watch crystal
• Set the movement back into the watch. Replace the old crystal gasket if it shows excessive wear or damage
• Use a watch crystal press or jeweler's epoxy two-part cement to install the new watch crystal into the crystal gasket or onto the bezel depending on how the previous watch crystal was held in place
