Replacement front screen outer glass lens for Watch GT 3 46mm MIL-B19. Replace the old, broken, cracked, or damaged screen. Restores your device with a refreshed appearance. Precisely fits and functions properly. Each item is inspected and in good condition prior to shipping. Professional installation is highly recommended. We are not responsible for issues arising after installation. Before Installation Notes: Tip 1: Test before installation. Do not remove any protective film or labels during testing. Be cautious of static electricity. Before starting repair, ground yourself using an ESD (electrostatic discharge) strap to prevent damage to internal electronic components. Wear eye protection and handle carefully to avoid injury from glass fragments. Tip 2: Perform a test fit before full installation. Screen replacements are fragile. Test functionality before final assembly. Temporarily connect the motherboard, LCD, and new screen with the o cable, then power on for testing. If the screen displays correctly, proceed with full installation. If there is no display, immediately. Do not force installation if the screen fails testing. Responsibility ends after installation. Tip 3: Avoid excessive bending of the cable. Do not bend the LCD cable beyond 90 degrees, as this may result in a black display.
