So basically my polarizing film makes LCD go rainbows when I put in on the wrong side, found it accidentally. And I had this watch laying around, waiting for it's youtube review to be made. But I had trouble thinking of something interesting to tell about this watch, so I just did a mod on it instead :D Readability is bad now, in some angles even worse then the negative display. But this watch has a very good back light and it works great with this mod as you can see in one of the pictures. One of the good things with this mod, that it is easily revertible if you have not applied any glue. So what do you think - negative or chameleon looks better?
