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 Ultra 3 nearly doubles the Series 11 battery life, and satellite emergency SOS works even without cellular or WiFi coverage.
More precise GPS tracking in urban canyons and dense forests — critical for trail running, mountaineering, and triathlon.
The 49mm titanium case and 3000-nit display make this watch usable in full direct sunlight and water depths up to 100m (EN13319 certified for diving).
