Setup: Watch Strap Installation
Installing your new Casio watch strap requires careful attention. It is recommended to use appropriate tools to avoid damage to your watch or the new strap.
Required Tools:
- A fine jeweler's flat-head screwdriver (approximately 1.0mm to 1.2mm tip)
- A soft cloth or protective surface
Installation Steps:
- Prepare Your Workspace: Place your watch face down on a soft, clean cloth to prevent scratches.
- Remove the Old Strap:
Locate the spring bars or screws that secure the current strap to the watch lugs. For this model, the strap is typically secured by screws. Using the fine jeweler's screwdriver, carefully unscrew the pins holding the old strap in place. Keep the screws and any small tubes or washers in a safe place, as they may be reused.
- Position the New Strap:
Align one half of the new strap with the corresponding lug on the watch case. Ensure the strap is oriented correctly (e.g., the buckle side typically attaches to the 12 o'clock position).
- Secure the New Strap:
Insert the screws through the strap and into the watch lugs. Gently tighten the screws with the screwdriver. Do not overtighten, as this can strip the screw heads or damage the watch case. Repeat this process for the other half of the strap.
- Verify Security:
Once both halves are installed, gently tug on the strap to ensure it is securely attached to the watch. There should be no looseness or play.

Wearing and Adjustment
The resin strap is designed for comfort and durability. To wear your watch, simply pass the end of the strap through the buckle and secure it using the tang. Adjust the strap to a comfortable fit on your wrist. It should be snug enough to prevent the watch from sliding freely, but not so tight as to restrict circulation or cause discomfort.
Maintenance
Proper maintenance will extend the life of your resin watch strap.
- Cleaning: Regularly clean the strap with mild soap and water. Use a soft brush or cloth to remove dirt and debris. Rinse thoroughly with clean water and dry with a soft towel.
- Avoid Harsh Chemicals: Do not expose the strap to strong solvents, detergents, or chemicals, as these can degrade the resin material.
- Storage: When not in use, store your watch in a cool, dry place away from direct sunlight to prevent material degradation over time.
Troubleshooting
- Strap Does Not Fit: Double-check the model number on the back of your watch against the compatible models listed in this manual. Ensure you have purchased the correct replacement strap.
- Screws Are Loose: Gently retighten the screws. If they continue to loosen, ensure the small tubes or washers (if present from the original strap) are correctly seated. Avoid overtightening.
- Discomfort: Adjust the strap to a different hole. If discomfort persists, ensure the strap is not twisted or improperly installed.
