The watch faces, which can completely change the impression of a smartwatch, can be downloaded from the "Huawei Health" app in addition to the ones installed by default. There are approximately 25,000 types available, and many free watch faces are also available. The watch uses Huawei's proprietary "TruSeen 5.5+" heart rate sensor. This enables highly accurate real-time heart rate monitoring and blood oxygen level measurement. By measuring 24 hours a day, real-time, the watch can notify you if any abnormal values are detected. In addition to heart rate and blood oxygen levels, you can also measure activity rings that measure the degree to which you have achieved your set goals, skin temperature, and stress levels. Of course, it also supports the recent trend of sleep monitoring. You can score the quality of your sleep from the total sleep time, deep sleep, light sleep, and REM sleep time, which can help you improve your sleep habits.
