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.
Training Readiness, full Training Status, and wrist-based running power — analytics previously reserved for Garmin's mid-range — now on a $299.99 watch.
A bright 1.2" AMOLED touchscreen with a traditional 5-button design, up to 10 days of battery in smartwatch mode and around 17 hours of GPS.
Contactless payments arrive on the entry Forerunner for the first time, alongside 80+ built-in sports apps and Garmin Coach adaptive training plans.
The right pick depends on what you optimize for.
$509 vs $699 over 3 years.

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 →Beginner and intermediate runners who want real GPS accuracy and Garmin's analytics depth without the price of the 570 or 970. With Training Readiness and running power now included, it closes much of the gap to Garmin's mid-range — the default first serious GPS watch.
