Deep feature set.

SURFACE MULTI-GNSS

Track your entry and exit2 points with advanced satellite connectivity.

DIVE LOG

Push performance to a whole new level.

SPORTS APPS

Use preloaded activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, golfing and more.

FITNESS AGE

This feature uses chronological age, your weekly vigorous activity and resting heart rate to estimate if your body is younger or older than you are. And you can get tips to lower your fitness age.

RECOVERY TIME

After each workout, recovery time lets you know when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep.

Training status

This metric evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching.

DAILY SUGGESTED WORKOUTS

For training guidance that takes you and your fitness level into account, get daily run suggestions based on your current training load and status.

ALL-DAY RESPIRATION

Track how you’re breathing throughout the day, during sleep, and during breathwork.

Tune in to your body and mind.

SLEEP SCORE AND ADVANCED SLEEP MONITORING

Get a full breakdown of your light, deep and REM sleep stages. View it all on a dedicated widget that includes your sleep score and insights.

INTENSITY MINUTES

Track how many minutes of vigorous activity you’re getting, when you earn them and during which activity. You can even view them as a data field during timed activities.

BODY BATTERY™ ENERGY MONITORING

Track your body’s energy levels so you can find the best times for activity and rest.

HYDRATION TRACKING

Log daily fluid intake as a reminder to stay hydrated. When auto goal is enabled, you’ll even see estimated sweat loss after an activity, and your goal will adjust accordingly.

WOMEN’S HEALTH TRACKING

Use the Garmin Connect™ app to track your menstrual cycle or pregnancy. Log symptoms, get exercise and nutrition education, and more.

WRIST-BASED HEART RATE

The watch constantly samples your heart rate4 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.

Designed for both your worlds.

SUPERIOR BUILD QUALITY

Enjoy a rugged, watch-style dive computer with a sapphire lens, silicone bands and an easy-to-read monochrome display.

SMART NOTIFICATIONS

Receive emails, texts and alerts right on your wrist when paired with a compatible device.
