Note: The screen protector is intentionally cut smaller than the display because the edges are curved. There is no impact on the display quality or touchscreen functionality. You will hardly notice any difference compared to a Rinsmola 1.69-inch smartwatch without a screen protector. Scratch-resistant due to the specially hardened surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Deliberately smaller than the Rinsmola 1.69-inch smartwatch glass, as it is curved (see photos), bubble-free and can be removed without residue at any time (no adhesive). Easy installation! No bubble formation possible on a dust-free display! When applying the film, air is displaced, and it adheres to the display almost by itself. Can be removed without residue at any time! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
