Note: The screen protector is intentionally cut smaller than the display because the edges are curved. Scratch-resistant, hard-coated surface with 3H pencil hardness. Very good reflection reduction. Reduces annoying glare and reflections on the display. The matte anti-glare film has a paper-like surface. Intentionally smaller than the Huawei Watch D glass due to its curvature (see photos), it is bubble-free and can be removed at any time without leaving residue (no adhesive). Easy application - 100% bubble-free installation on a cleaned display! The special silicone adhesive layer displaces air during application and naturally conforms to the display. No impact on usability! The Dipos screen protector provides a pleasant touch experience and is optimized for the Huawei Watch D.
