Surface Multi-GNSS: Track your entry and exit points with advanced satellite connectivity including GPS, GLONASS and Galileo support

Dive Log: Store and review data for up to 200 dives — and share via the Garmin Dive app6

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.

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 rate 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.

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

Battery Life: Stay in the water longer with up to 25 hours in dive mode, 21 days in smartwatch mode and 26 hours in GPS mode.

Safety and tracking Features: When your watch and phone are paired, your live location can be sent to your contacts manually or — during select outdoor activities — automatically with built-in Incident Detection5.

Garmin Pay™ Contactless Payments: Breeze through checkout lines with Garmin Pay contactless payments6 through participating providers.

Connect IQ™ Store: Download custom watch faces, add data fields, and get apps and widgets from the Connect IQ Store

Tide Date: Stay up to date on ocean conditions so you can catch the perfect wave. Just pair the watch with your compatible smartphone.
