Setup and Installation
Installing your new Casio watch strap requires careful handling to avoid damage to your watch or the strap. A spring bar tool is recommended for this process.
- Prepare Your Workspace: Lay your watch face down on a soft, clean cloth to prevent scratches. Ensure you have good lighting.
- Remove the Old Strap:
- Locate the spring bars that hold the current strap to the watch lugs.
- Using a spring bar tool, gently compress one end of the spring bar and pull the strap away from the watch case.
- Repeat for the other side of the strap and for the second strap piece. Retain the old spring bars if they are in good condition, as new ones are not typically included with the replacement strap.
- Inspect Spring Bars: Examine your existing spring bars for any bends or damage. If they are compromised, it is recommended to acquire new ones for a secure fit.
- Attach the New Strap:
- Insert one end of a spring bar into a lug hole on the watch case.
- Place one piece of the new strap between the watch lugs.
- Using the spring bar tool, compress the other end of the spring bar and guide it into the opposite lug hole. Ensure both ends of the spring bar are securely seated in the lug holes.
- Gently tug on the strap to confirm it is firmly attached and does not easily detach.
- Repeat this process for the second piece of the watch strap.

Operating Instructions
Once installed, the watch strap is ready for use. Adjust the strap to a comfortable fit on your wrist.
- Wearing the Watch: Place the watch on your wrist. Insert the end of the strap through the buckle and secure the tang (pin) into one of the adjustment holes.
- Adjusting the Fit: Select an adjustment hole that allows the watch to sit snugly but comfortably on your wrist. It should not be too tight to restrict circulation, nor too loose to slide freely.
- Securing the Excess Strap: Thread the excess strap through the keeper loops to prevent it from flapping.
Maintenance
Proper maintenance will extend the life and appearance of your Casio watch strap.
- Cleaning: Clean the silicone strap regularly with mild soap and water. Use a soft cloth or brush to gently scrub away dirt and grime. Rinse thoroughly with clean water and dry completely with a soft towel.
- Avoid Harsh Chemicals: Do not use strong detergents, solvents, or abrasive cleaners, as these can damage the silicone material.
- Storage: When not in use, store the watch in a cool, dry place away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the strap for any signs of wear, cracks, or damage, especially around the lug attachments and buckle.
