2. Strong endurance
As a running watch, it should be able to support at least one marathon. Usually 6 hours is no problem at all.
3. Lighter design

4. Accurate heart rate detection
Although there is a certain error in photoelectric heart rate, the heart rate monitoring function of various brands has been done very well at present. If you wear it correctly, the basic and heart rate band errors are not big. In addition, the function of sports watches is not only to measure heart rate.
5. Accurate GPS positioning
