I bought Apple Watch about two weaks ago and today I noticed (against the sun) that I see like four vertical bars going from the top of the display to bottom of the display. The bars are noticable at the top and the bottom and they are disappearing in the center. The spaces between them are similar. They are noticable even if the screen is of and also the corners of the display seem to be little lighter (not perfectly black). But you don't see them when display is on. It might be just how the display is build, but I'm a little worried that the display might be badly glued or something. Do you have something similar on yours? Thanks.
