Black Front Glass for Samsung Galaxy Watch 42mm (R810 / R815) – Not a Screen Protector

Black front glass replacement for the Samsung Galaxy Watch 42mm, designed to replace the outer glass only when cracked or scratched, provided that the AMOLED screen and touch panel are still functional.

This is not a tempered glass or screen protector – it is the actual front glass component, with the exact curvature and thickness of the original. Intended for professional use, installation requires UV adhesive, proper tools, and technical skill due to the smartwatch's compact assembly.
