This screen guard is designed to protect the display of a smartwatch. The installation process involves four simple steps: first, clean the smartwatch surface thoroughly with the provided wet wipe, ensuring no dust remains. Next, peel off the black protection layer using Sticker 1 and carefully place the screen guard, ensuring it correctly covers the edges of the smartwatch display. Then, peel off the upper blue layer using Sticker 2. Finally, if required, clean the surface again to achieve crystal clarity. This product is compatible with smartwatches.
