First, the film itself is very good, good adhesion and good material, but unfortunately she is working a little too exact fit. The SmartWatch has this aluminum rim which protrudes a little bit on the display, so that when the film it is a clean transition occurs. But here's the also the crux of the matter, since the film is made to exactly, it is not possible to assemble the film without somewhere stops at the edge and as air and dirt is less. If the film on the edge about a 1/5 mm would be smaller in total, you could install them better. Had at one point with the nail scissors himself thus create it exactly anywhere on the screen is. Of course this can also be due to the manufacturing tolerance of the SmartWatch, but that should be considered the film manufacturer actually.
