Scratches on a watch crystal can take away from the beauty of your timepiece. Fortunately, if your watch has an acrylic (plastic/plexi) crystal, you can restore clarity at home using Polywatch Polishing Paste.
This DIY guide shows you exactly how to remove light to moderate scratches safely and effectively, no professional tools required.

Polywatch is a fine abrasive polish designed specifically for acrylic watch crystals. It works by gently removing a microscopic layer of plastic to smooth out scratches and improve transparency.
Important: Polywatch should only be used on acrylic crystals. It is not suitable for sapphire or mineral glass.

Can You Use Polywatch More Than Once?
Yes. Polywatch is safe to use multiple times on acrylic crystals. However, since polishing removes a tiny layer of material, avoid excessive use unless needed.
When Polywatch Won’t Work
Polywatch may not be effective if:
- The crystal is sapphire or mineral glass
- Scratches are very deep
- The crystal is cracked or chipped
In these cases, professional polishing or crystal replacement is recommended.
