Battery life of up to 20 days with solar charging (assuming all-day wear with 3 hours per day outside in 50,000 lux conditions)
Battery life of up to 42 hours in GPS mode and up to 49 hours with solar charging (assuming continuous use for entire period in 50,000 lux conditions)

Battery life up to 110 hours in UltraTrac™ mode with solar charging (assuming use in 50,000 lux conditions)
GPS has improved accuracy in areas where GNSS signals are reflected, weak or typically don't penetrate—giving you superior accuracy for how far and how fast you've run
Race widget provides training tips, personalized daily suggested workouts and completion time predictions based on course details, weather and performance
View your entire week of daily suggested workouts, which adapt after every run to match your performance and recovery
Smartwatch mode provides a full picture of your health—from sleep to training
Morning report gives you an overview of sleep, recovery, training and more, alongside heart rate variability (HRV) status
With HRV status, gain an understanding of your overall health, recovery and training performance (this device is intended to give an estimate of your activity and metrics)
HRV status through HRV while you sleep is based on technology developed by the Garmin Firstbeat Analytics™ team
You can customize your morning report to show what you want to see, including training readiness and weather
Indicators such as HRV status, your recent exercise history and performance give an insight into your overall effort with training status
Training readiness score is based on your sleep quality, recovery, training load and more, so you can determine whether it's a good day to go hard—or take it easy
Real-time stamina helps track and manage your exertion so you can avoid overexerting yourself at the start of your run or bike ride
When using a Running Dynamics Pod or HRM-Pro™ monitor (not included), the watch measures running metrics such as cadence, stride length, ground contact time and balance
30+ activity profiles include cycling, triathlon, pool and open-water swimming, track running and more; for races or brick workouts, switch sports with a single button press
If you feel unsafe or if your watch senses that an incident occurred, assistance and incident detection features send messages with your location to your emergency contacts
Incident detection is enabled by default for select activity profiles only; it requires setup and your smartphone to be in an area with network coverage with data connectivity
