Battery & Power
- Battery life of 6+ days. Battery life and charge cycles vary with use, settings and other factors; actual results will vary. Use of the always-on display, SpO2 and the cEDA sensor will require more frequent charging. Up to 5 hours with continuous GPS. We recommend charging your tracker every few days to ensure you are always tracking.
- Battery type: Lithium-polymer
- Charge time (0-100%): Two hours
- Charge 12 minutes to get one day of battery life
- Radio transceiver: Bluetooth® 5.0
Memory
- Saves 7 days of detailed motion data, minute by minute
- Saves daily totals for the last 30 days
- Stores heart rate data at one-second intervals during exercise tracking and at five-second intervals all other times
Materials
This watch includes a band made of a flexible material similar to that used in many sports watches, as well as an aluminium watch case and buckle.
Heart Rate
Like all heart rate tracking technologies, accuracy is affected by physiology, location of device and different movements.
