How to Install

1. Remove your existing watch strap (if applicable).
2. Locate the quick‑release pins on the new silicone strap.
3. Press the spring‑loaded pin inward on one side of the strap.
4. Insert the pin into the lug hole on your watch.
5. Release the pin to secure it in place.
6. Repeat for the other side of the strap.
7. Adjust the strap to your wrist size using the buckle and holes.

Installation Time: Typically 1–2 minutes, no tools required.

Care Instructions

• Wipe the strap with a damp cloth to remove sweat, dirt and oils after exercise or daily wear.
• Rinse with water and mild soap if needed, then allow to air dry.
• Do not expose to harsh chemicals, solvents or abrasive cleaners.
• Avoid prolonged exposure to direct sunlight, which may cause fading over time.
• Check the quick‑release pins regularly to ensure they are secure.
• Replace the strap if you notice signs of wear, cracking or damage.

Usage Notes

• Always measure your watch's lug width before purchasing to ensure compatibility.
• The strap is designed for watches with standard lug widths (18mm, 19mm, 20mm, 22mm).
• Silicone material is flexible and comfortable but may attract dust and lint over time.
• Colour may vary slightly from images due to lighting and screen settings.
• The strap is sweat‑resistant and can withstand water splashes, but it is not designed for swimming or submersion unless your watch is waterproof.
• Wrist size fit depends on the width selected and the position of the holes used.
