The display of the SmartWatch 3 is slightly curved toward the edge, the glass is therefore not completely flat. Since the film is quite stiff, this curvature has unfortunately the effect that the foil around the edge of the display is not applied and does not stick. This not only looks extremely ugly, but certainly also means that including the time collects dust. Too bad, I have the same film for the Sony Xperia Z3 Compact where it fits perfectly, but for the SmartWatch 3 it is in my opinion not recommended.
