How to Remove Scratches from Glass Watch Crystals

Some scratches can be removed from glass crystals using basic tools. If you have lapidary tools available, you can remove deep scratches from flat surfaces. After trimming a glass crystal down to fit, crystal fitters will bevel the glass to prevent leaving a sharp edge and having the glass chip the bevel looks much nicer when it is polished to a high shine. In this guide you will learn how to polish glass crystals edges and remove small scratches from the flat surface.

Watch Tools Required:
Hard felt Buff or lap
Polishing Motor
Yellow rouge 
Polyimide tape or masking tape
Soft crystal cleaning cloth

Step 2

Step 3

 

Use medium pressure and keep moving – stop several times at the start of the polishing to observe the results – you can apply more pressure for deeper scratches and add polishing compound if needed (the watch crystal should heat up very slightly during polish, take longer breaks or press less if the buffing is feeling hot to touch

Face the crystal directly at the buff change positions and move at angles to polish the edges and equally

For curved crystals be sure to keep your and moving so that the crystal is polished along the curve equally.

 

 

 

Step 4

 

 

Remove masking tape and use a soft cloth to remove excess polishing compound from around the watch crystal.
