A watch crystal is typically the window covering the watch dial from dirt, dust, or water. Therefore, a watch crystal is very important as it protects the internal mechanism of the watch from external harm.

There are three types of crystals commonly used as wristwatch glass covers. Each one is different in terms of scratch resistance, durability, and affordability.

1.) Acrylic Crystal

Step 1: Protect your watch.

The very first thing to do before you polish your watch is to protect it. You need to cover all parts of the watch near the crystal with a painter’s tape. Take special precautions to cover the watch bezel, which is the outer ring that surrounds the watch crystal. Covering with the painter’s tape will prevent the rest of your watch from damage. Also, remove the watch straps if you can easily remove them.

 

Step 2: Apply a small amount of polish.

Squeeze out a small amount of polish onto the surface of the watch crystal. Avoid squeezing too much as it may spill all over the place. Just a small amount of polish can get the job done. With the Dia-Paste 3-micron compound, a small amount is just enough.

 

Step 3: Begin Buffing

With a soft microfiber cloth, gently buff the polish in small circles around the watch crystal to remove scratches from watch face.  Keep the pressure light as you buff out scratches in a circular motion until you polish the scratches out of glass. After a few minutes of buffing, the scratches will eventually disappear. The polish will give your crystal the glass-like finishing it once had. Once you achieve the perfect results, wipe away the excess paste and inspect your work.

 

Step 4: Consider replacing the crystal

If you can’t get rid of the scratches because they are too deep, consider replacing the watch crystal. If you have the options, consider returning the watch to the manufacturer. Ask them to replace the watch crystal. However, one drawback to this is, unless it’s a recent model, most manufacturers might not have the watch glass replacements. As an alternative also, consider changing the crystal at a local repair shop.
