Amazfit Stratos 3
The Stratos 3 falls in line with Amazfit's previous sports-centric watches. It has a round design with a 1.34" transflective display for better outdoor readability, a breathable silicon strap, and four physical buttons. You'll also get 5 ATM water resistance, a built-in GPS, and a continuous heart rate monitor.
When used with Huami's own software and set to an "Ultra Endurance Mode," the Stratos 3 can last up to 14 days (35 to 70 hours in GPS mode) while still letting you monitor your heart rate, get notifications, and track your activity across 11 different sports (including swimming).
19 Different Sports Modes
In addition to the well-known modes such as jogging (indoor, outdoor), walking, cycling (indoor, outdoor), swimming, stepping, skiing and free training, there are dedicated sports such as football and tennis. For data analysis, the watch uses the FIRSTBEAT algorithm, which is also widely used by professional athletes.
1.34-inch Full Moon Color Display
The so-called FullMoon display is therefore always on and even better readable in strong sunlight.
70 Hours Battery Life With Gps Tracking
Amazfit Stratos 3 supports the choice of GPS continuous working mode for up to 70 hours in cross-country running, outdoor hiking and mountaineering mode.
