Installation Guide
Follow these steps carefully for a successful, bubble-free installation of your screen protector.
- Prepare Your Workspace: Ensure you are in a clean, dust-free environment. Wash your hands thoroughly to avoid transferring oils to the screen or protector.
- Clean the Smart Watch Screen:
- Use the provided alcohol wipe to thoroughly clean the smartwatch screen, removing all dirt, oil, and smudges.
- Immediately follow with the microfiber cloth to dry the screen completely and remove any streaks.
- Use the dust-absorber sticker to pick up any remaining dust particles. Ensure the screen is perfectly clean and dry before proceeding.
- Align the Screen Protector:
- Carefully peel off the protective film from the adhesive side of the tempered glass (usually marked "1" or with a tab). Avoid touching the adhesive surface.
- Align the screen protector precisely with the edges and cutouts of your smartwatch screen. Take your time to ensure perfect alignment.
- Apply the Protector:
- Once aligned, gently lower the screen protector onto the smartwatch screen. The adhesive will begin to spread automatically.
- If bubbles appear, gently press them towards the edges of the screen using the microfiber cloth or a soft card. Small bubbles should disappear within 24-48 hours.


Maintenance and Care
To maintain the clarity and effectiveness of your screen protector, follow these simple care guidelines:
- Regular Cleaning: Use a soft, lint-free microfiber cloth to gently wipe the screen protector. For stubborn smudges, slightly dampen the cloth with water or a screen cleaner specifically designed for electronics.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, alcohol (other than the initial cleaning wipe), or solvents, as these can damage the oleophobic coating.
- Protect from Sharp Objects: While the protector is 9H hard, extreme force or very sharp objects can still cause damage. Avoid placing your smartwatch face down on rough surfaces or with keys/coins.
Troubleshooting
Here are solutions to common issues you might encounter during or after installation:
- Bubbles After Installation:
- Small Bubbles: Most small bubbles will naturally disappear within 24-48 hours as the adhesive settles.
- Large Bubbles/Dust Particles: If a large bubble persists or you see a dust particle, gently lift the nearest corner of the protector with a fingernail or a thin card. Use a dust-absorber sticker to remove the dust, then re-apply the protector slowly.
- Misalignment: If the protector is significantly misaligned, gently lift it from one corner and re-align it carefully. Avoid excessive force to prevent damage.
- Edges Not Sticking: Ensure the screen was thoroughly cleaned and dry before application. If edges still don't adhere, gently press them down for a few seconds. Extreme cases might indicate a faulty protector or an incompatible screen curvature.
