3. Installation Instructions
Installing your new Casio watch strap requires careful handling to avoid damage to your watch or the new band. It is recommended to use a spring bar tool for this process.
3.1 Tools Required:
- Spring bar tool (recommended) or a small, flat-head screwdriver.
- Soft cloth to protect your watch.
3.2 Removing the Old Watch Strap:
- Place your watch face down on a soft cloth to prevent scratches.
- Locate the spring bar at one end of the watch strap, connecting it to the watch lug.
- Using the spring bar tool, gently compress one end of the spring bar and pull the strap away from the watch lug.
- Once one end is free, the spring bar can be removed. Carefully set aside the spring bars as they will be reused.
- Repeat the process for the other side of the strap.
3.3 Installing the New Watch Strap:
Important: This replacement strap does not include new spring bars. You must reuse the original spring bars from your watch.
- Insert one of the original spring bars into the channel at the end of the new strap.
- Align one end of the spring bar with the hole inside the watch lug.
- Using the spring bar tool, compress the other end of the spring bar and guide it into the corresponding hole on the opposite side of the watch lug.
- Gently tug on the strap to ensure both ends of the spring bar are securely seated in the lug holes. A slight click may be heard.
- Repeat the process for the other half of the new watch strap.

4. Usage and Care
Once installed, your Casio watch strap is ready for use. To ensure its longevity and maintain its appearance, follow these general care guidelines:
- Avoid Harsh Chemicals: Do not expose the strap to strong chemicals, solvents, or abrasive cleaners, as these can degrade the PVC material.
- Temperature Extremes: While durable, prolonged exposure to extreme heat or cold can affect the material's integrity.
- Secure Fit: Ensure the strap is fastened securely but comfortably on your wrist. An overly tight strap can cause discomfort, while a loose strap may lead to the watch shifting or falling off.
5. Maintenance
Regular cleaning will help keep your watch strap in good condition.
5.1 Cleaning Instructions:
- Wipe the strap periodically with a soft, damp cloth.
- For more thorough cleaning, use a mild soap solution (e.g., diluted dish soap) and a soft brush to gently scrub the strap.
- Rinse thoroughly with clean water and dry completely with a soft, lint-free cloth before reattaching to your wrist.
6. Troubleshooting
If you encounter issues with your watch strap, consider the following:
6.1 Strap Does Not Fit:
- Check Compatibility: Ensure your watch model is indeed a Casio W-800H or W-800HG. This strap is designed specifically for these models.
- Verify Spring Bar Placement: Confirm that the spring bars are correctly seated in both lug holes. If not, the strap may feel loose or detach.
- Inspect Lug Width: The strap's shoulder size is 24.5mm. Measure your watch's lug width to confirm it matches.
6.2 Strap Breaks Prematurely:
- Review Usage: Assess if the strap has been subjected to excessive stress, sharp objects, or harsh chemicals.
