No other GPS watch currently on the market delivers 140 hours of GPS tracking — enough for most ultra-endurance events and multi-day mountain traverses.
GPS + GLONASS + Galileo + BeiDou + QZSS with dual-frequency reduces error in challenging terrain to near-meter precision.
Military-grade scratch and impact resistance for the harshest environments: extreme altitude, cold, and sustained physical stress.
The Smart Band 10's 1.72" display peaks at 1500 nits — 200 nits brighter than the Band 9 — making it more readable in sunlight, all for around $40.
Continuous heart rate, SpO2, stress, and sleep tracking — all running for 3 weeks before charging. Seven more days than the already impressive Band 9.
Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends. Bluetooth 5.4 for improved connection stability.
