1. The dial does not always light up when you look at the clock. You have to move your hand again. Mostly this happens in the supine position. When you are in a standing position, the dial is more readily activated when you make a movement with your hand to look at the clock.
2. Despite the large selection of watch faces in the Huawei Health application, I would like to have the opportunity to create the watch face myself. For example, I need the dial to show only time in numbers, weather, sunrise / sunset time, charge level, pulse and nothing more. It was with this combination of indicators that I did not find the dial. There were options with such values, but they still have a lot of everything superfluous, namely with such a set that there were no more, no less values, I did not find it.
3. The indicator of the level of oxygen in the blood (saturation), in my opinion, overestimates by 2-3 percent. So I compared the readings with a heart rate monitor, after pneumonia, the indicator on the heart rate monitor showed the same value every day - 96 percent, while the watch readings were 98-99 percent, sometimes even 100 percent, which definitely should not be. Although here one cannot completely trust the accuracy of either the readings of the Chinese heart rate monitor or the clock.
