How Do You Cut And Trim Plastic Watch Crystals?
In this guide you will learn how to cut down or trim plastic crystals. Many times when you have a watch crystal to fix or replace you may need to reduce the size of the crystal slightly to fit the watch. Modifying plastic watch crystals many times takes very little effort and can save time and money by allowing you to use a crystal that you own rather than purchasing a new crystal. After you have trimmed your plastic crystal you will want to read on how to polish plastic crystals to get a high shine on the finished job. Holding the crystal firmly in one hand begin to file back and forth with light pressure (on the edge that needs to be cut) Observe results before applying more press to cut faster. Use the flat side of the file and try to stay at a 90 degree angle from the top and bottom of the crystal while filing. Turn the crystal slowly while holding it to file evenly over curved surfaces. Use very light pressure and clean any chips from the edge of the crystal.
