4. Installation Guide
This section outlines the general steps for replacing your watch strap. If you are unsure about any step, it is recommended to seek assistance from a professional watchmaker to avoid damage to your watch or the new strap.
4.1 Tools Required
- Spring bar tool (or a small, flat-head screwdriver)
- Soft cloth or protective mat
- Original watch buckle (if reusing)
4.2 Removing the Old Strap
- Place your watch face down on a soft cloth or protective mat to prevent scratches.
- Locate the spring bars that secure the strap to the watch lugs.
- Using a spring bar tool, gently compress one end of the spring bar and carefully pull the strap away from the watch case.
- Repeat for the other side of the strap and then for the second strap piece.
- If reusing your original buckle, use the spring bar tool to remove it from the old strap.
4.3 Installing the New Strap
- If reusing your original buckle, attach it to the shorter piece of the new rubber strap using the spring bar. Ensure it is securely fastened.
- Insert one end of a spring bar into the lug hole on one side of the watch case.
- Align the new strap piece with the watch lugs. Using the spring bar tool, compress the other end of the spring bar and guide it into the corresponding lug hole on the opposite side.
- Gently tug on the strap to ensure the spring bar is fully seated and the strap is securely attached.
- Repeat the process for the second piece of the rubber strap.
- Verify that both strap pieces are firmly attached and the buckle is correctly oriented.

5. Care and Maintenance
To maintain the appearance and longevity of your Ewatchparts rubber watch strap, follow these care guidelines:
- Cleaning: Regularly clean the strap with mild soap and water. Use a soft cloth to gently wipe away dirt and debris. Rinse thoroughly with clean water.
- Drying: Allow the strap to air dry completely after cleaning. Avoid direct sunlight or excessive heat, which can degrade the rubber material over time.
