I had the first Apple Watch before I updated. By the way everyone way praising it, I was expecting it to be absolutely amazing and make the first Apple Watch look like absolute garbage in comparison. However, I’m honestly starting to miss my old watch. I’m having problem with it. First the screen sometimes won’t turn off when I cover it because the screen is too big, while my 42m original always did. Also, the screen doesn’t always turn on when I move the table in Nightstand and 3rd party app compilations I used before don’t support the new watch face. I think both could be fixed with time, but the original was nearly problem-less on its latest 4.3.2 software. Looking back, if you still have use the original model, you don’t need to upgrade yet. The speed is actually good enough even though it’s slow. You’re getting stability and completeness in place of speed and features.
