When I started looking at G-shocks on the internet, I was drawn in by the negative displays, and was not aware that all those photos / videos etc were carefully shot in correct lighting to show the optimal view of the display. When I was looking to buy my son his G7900-1, I originally alos bought the G7900B-1 to check it out. I went to Macy's, and of course the readability was great it the display case with its ample / directed lighting. Then out of the case in the store lighting, it was less readable, but still good enough I did not fret. However, when I got it home to my east / west facing home with its poor natural lighting, it was barely readable in most natural light conditions in the house. Even outside under the patio and other places, I just was not impressed. It was returned the next day.
Since then I have tried the GLX-150, the G7900KG-3 and a couple of others hoping different ones would perform better, but no dice.
I read that some folks have no trouble reading them in all sorts of conditions, some on this thread, but I scratch my head - is the readabililty a personal eyesight / contrast thing where some can read them better than others? I don't get how some say they don't have any issues with the negative display when so many do???
