This product is a screen protector only and is not a smartwatch. Please read carefully before ordering. It is made from PMMA plastic material that is flexible, durable, and shatter-resistant for long-lasting use. The HD high-transparency surface provides a clear, bright, and natural display view. Designed with full coverage, it protects the entire smartwatch screen edge to edge from daily scratches, dust, and marks. The smooth plastic watch film ensures super quality and long-lasting protection. Installation is simple by cleaning the display with wet and dry wipes, then carefully aligning and applying the protector. If any difficulty occurs during installation, customer support is available.
