Built for professional sports, the Amazfit Stratos 3 adopts a 1.34-inch full round transflective MIP display perfectly suitable for outdoor use; the brighter the light is, the clearer the display looks. The four physical buttons enable you to browse through the features and control the device without using the touch screen. This is especially useful while running or when your hands are shaky after intensive workouts. The 316L stainless steel body combined with reinforced plastic makes the watch robust while minimizing its weight, and the black silicone strap facilitates the ventilation and perspiration.

Huami Technology's proprietary BioTrackerTM PPG bio-tracking optical sensor brings heart-rate monitoring accuracy to a new level, which is comparable to the accuracy of sports heart rate bands. In addition to the 24-hour heart-rate monitoring, it provides warnings on excessively high heart rate and heart rate interval values. The integrated Sony GNSS chips support four different global positioning systems: GPS, GLONASS, BEIDOU and GALILEO. You can combine any two of them to form three different positioning patterns, which enhances the positioning speed and tracking accuracy.
