Identify the Major Types of Watch Crystal/Glass
The type of watch crystal affects durability and repair options. Below are 3 types of watch crystal that will help you choose the best method for scratch removal.
Acrylic (Hesalite / Plexiglass)
Acrylic is lightweight, shatter-resistant, and often used in vintage watches. It scratches easily, but most light scratches can be polished at home using products like Novus 2.
Mineral Crystal
Mineral crystal is tempered glass that resists scratches better than acrylic. It is common in mid-range watches. While harder to polish than acrylic, using the right glass polishing compound can reduce or remove light scratches.
Sapphire Crystal
Sapphire crystal is extremely scratch-resistant, making it a favorite for luxury watches like Rolex, Omega, and Patek Philippe. Deep scratches are hard to remove and may require professional tools or crystal replacement.
How to Assess the Scratch on Your Watch Glass
Not all scratches are the same. Checking the depth, material, and location helps you decide whether to fix it yourself or seek professional help.
1. Check the Depth of the Scratch
- Light scratches only touch the surface. You can usually polish them at home using products like Novus Plastic Polish for acrylic crystals.
- Deep scratches cut through the crystal. You may need professional tools or even a crystal replacement, especially for luxury watches like Rolex, Seiko, or Omega.
2. Identify Your Watch Crystal Material
- Acrylic crystals are softer and easier to polish yourself.
- Mineral and sapphire crystals are much harder. You can handle light scratches with specialized removers, but professionals should repair deep scratches.
3. Examine the Scratch Location
- Center scratches stand out and distract from your watch’s look.
- Edge scratches appear less obvious, but they can still hurt your watch’s appearance and resale value.
How to Remove Scratches from Watch Glass
Scratches on your watch glass can make your timepiece look dull and harder to read. The steps to fix them depend on the type of crystal. Here’s how you can tackle scratches safely at home.
For Acrylic Crystal
Acrylic crystals are soft, so you can polish them easily at home. With the right tools, you can restore your watch glass yourself. Follow these steps:
Step 1: Gather your materials
Grab a soft cloth, plastic polish like Novus 2, and some water. Having everything ready before you start makes the process smoother and prevents mistakes.
Step 2: Clean the surface
Wipe your watch glass to remove dust and debris. Cleaning ensures that no dirt scratches the crystal further while you polish.
Step 3: Apply the polish
Place a small amount of polish on the cloth. Make sure to use just enough to cover the scratch without over-applying.
Step 4: Buff the scratch
Rub the scratched area in gentle, circular motions for a few minutes. Applying consistent, light pressure helps remove scratches without damaging the acrylic.
Step 5: Wipe clean
Remove excess polish with a damp cloth. Cleaning between buffing steps prevents residue from building up and lets you see your progress.
Step 6: Inspect and repeat
Check the scratch after each round of polishing. Repeat the process if the scratch is still visible until the glass looks smooth and clear.
For Mineral Glass
Mineral glass is harder than acrylic, so it requires a glass polishing compound. You can handle light scratches at home, but deep scratches may need professional help.
Step 1: Assemble equipment
Gather a glass polishing compound, a microfiber cloth, and some water. Having everything ready prevents interruptions.
Step 2: Prep the area
Clean your watch glass thoroughly to remove dust and dirt. A clean surface ensures the compound works effectively.
Step 3: Apply the compound
Put a small amount onto your cloth. Use only enough to cover the scratched area.
Step 4: Rub the scratch
Polish in gentle, circular motions for a few minutes. Consistent, light pressure removes scratches without damaging the glass.
Step 5: Rinse the area
Remove excess compound with water and pat dry. This helps you see your progress and prevents residue buildup.
Step 6: Final check
Inspect the scratch and repeat if necessary. For deep scratches, consider a professional watchmaker.
For Sapphire Crystal (Including AR-Coated Crystals)
Sapphire crystals are very hard and often have anti-reflective coatings, so polish carefully. Light scratches can improve at home, but deep scratches usually need a professional.
Step 1: Check for AR coating
Confirm if your watch has an anti-reflective coating. Use a polish compatible with AR coatings to prevent damage.
Step 2: Gather materials
Collect sapphire polish or jeweler’s rouge and a soft cloth. Having the right tools prevents further scratching.
Step 3: Clean the scratch
Remove dust and dirt using a microfiber cloth. Cleaning allows the polish to work effectively.
Step 4: Apply polish carefully
Place a small amount on the cloth and rub gently. Work slowly and avoid heavy pressure to protect the coating.
Step 5: Buff gently
Rub in light, circular motions. This removes scratches without compromising the crystal or coating.
Step 6: Wipe down
Clean the surface and inspect the scratch. Repeat only if necessary, or consult a professional for deep scratches.

FAQs About How to Remove Scratches from Watch Glass
Can toothpaste remove scratches from watch glass?
Toothpaste can gently polish light scratches on acrylic crystals, but it may damage harder mineral or sapphire glass. The effectiveness depends on the scratch depth and crystal type. Use it sparingly and avoid aggressive rubbing, as overuse can worsen scratches or dull the surface, especially on high-quality or coated crystals.
Can I remove scratches from sapphire crystal at home?
Light surface scratches on sapphire crystal may be polished with specialized polishing compounds or kits, but deep scratches usually require professional repair or crystal replacement. Attempting DIY methods can lead to further damage, so it’s safer to consult a professional watchmaker or service center for high-value or luxury watches.
How do I know if my watch has an AR coating?
Anti-reflective (AR) coatings often create subtle blue or greenish reflections on the crystal under light. You can also check manufacturer specifications or ask a professional watchmaker. Correctly identifying an AR coating is important because polishing it improperly can remove or damage the coating, reducing visibility and aesthetic appeal.
Is it safe to polish my watch glass repeatedly?
Frequent polishing can gradually wear down softer crystals, such as acrylic, and damage coatings on mineral or sapphire glass. Gentle, occasional polishing is recommended for minor scratches. For persistent or deeper scratches, it’s safer to seek professional polishing tools or crystal replacement to avoid compromising the watch’s clarity and structural integrity.
How much does crystal replacement cost?
Replacement costs vary by material and watch model. Acrylic or mineral crystals typically range from $50–$100, while sapphire crystals can cost $150–$300 or more, especially for luxury watches. Professional service ensures proper fitting and finishing, which preserves water resistance and overall watch performance.
