WRIST-BASED HEART RATE
The watch constantly samples your heart rate2 with our latest-generation heart rate sensor and will alert you if it stays too high or too low while you’re at rest. It also helps gauge how hard you work during activities — even while swimming.
BODY BATTERY™ ENERGY MONITORING
Track your body’s energy levels so you can find the best times for activity and rest2.
IMPROVED SLEEP MONITORING AND SLEEP SCORE
Understand how your body is recovering — and get ready for training — with our improved sleep monitoring feature. After waking up, you’ll receive a sleep score, as well as breakdown of your sleep stages, Pulse Ox3 and respiration, alongside detailed insights for improved sleep quality.
PULSE OX SENSOR
This wrist-based Pulse Ox sensor3 monitors blood oxygen saturation levels to support advanced sleep monitoring and altitude acclimation.

Use the Garmin Connect app to track your menstrual cycle or pregnancy. Log symptoms, get exercise and nutrition education, and more. Even see and log details on your wrist with the Women’s Health Tracking app.
INTENSITY MINUTES
Our intensity minutes feature tells you when during the day you earned them and during what activity.
STRESS TRACKING
Find out if you’re having a calm, balanced or stressful day. Relax reminders will even prompt you to do a short breathing activity when the watch detects that you’re feeling stressed.
HEALTH SNAPSHOT™ FEATURE
Log a 2-minute session to record key stats, including heart rate2, heart rate variability, Pulse Ox3, respiration and stress. Then generate a report with those stats to share via the Garmin Connect app on your compatible smartphone.
Stay connected at every step.
MULTI-BAND GNSS SUPPORT
