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.
A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.
Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.
Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.
The right pick depends on what you optimize for.
$476 vs $699 over 3 years.
140 days vs 7 days battery.
5 sensors · 0.5 Hz HR sampling.
18g.
Expedition athletes, mountaineers, and ultra-endurance competitors who do multi-day or multi-week events where charging is impossible. If you need GPS tracking for 140 continuous hours, no other watch comes close.
Full details →Anyone who wants a slim tracker with a screen, built-in GPS, and ECG rather than a full smartwatch. It suits Charge owners ready to upgrade, as long as they don't rely on Google Wallet payments or EDA stress scans. Works with both Android and iPhone via the Google Health app.
