not to diss polywatch ... but I bought a bottle of "generic poly carbonate headlight polish" ... big ass bottle for 0.99 ... its the same - works the same When you are done and start seeing results, wipe off any residue from the crystal. You can do this with a clean cloth. The short answer is that yes, Polywatch works to remove scratches from watch crystals. Note, however, that this only applies to watch crystals made of plastic, hesalite, or acrylic. Polywatch will not work on sapphire or glass crystals as the abrasive material is not able to grind down the glass as it can with plastic. If you use Polywatch on glass crystals, it can instead cause scratches. How does PolyWatch work? old t-shirt .... moisten lightly with some finger's worth of water until it results in a "wet-spot" (insert dirty joke here) ... then a bit of the polish (fingernail sized drop) ... then I gently work the mustardy-paste into the wet spot until all the excess is in the fabric (about 2-3" across).

Polywatch is especially great for superficial hairline scratches as it doesn’t require a lot of grinding of the plastic material on the crystal. However, PolyWatch also works well for deeper scratches, although you need to apply more pressure and polish for a longer period of time. When you are done, it will leave your acrylic or plexi crystal flawless and free of scratches, allowing perfect legibility onto the dial. The benefit of this is that you don’t have to replace your whole watch crystal in case it only has scratches. This is both a cheaper and more effective alternative. I apply Polywatch with a slightly damp cloth and rub in a circular manner. Works great on acrylic crystals and, with enough elbow grease, will even remove some fine scratches from mineral glass.

PolyWatch is a cream that contains a very light abrasive material that will gently but effectively grind down your acrylic/plastic watch glass crystal, resulting in a scratch-free finish.
