Deep feature set.
DIVE MODES
Get multiple dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather.
SURFACE MULTI-GNSS
Track your entry and exit2 points with advanced satellite connectivity.
DIVE LOG
Store and review data for up to 200 dives — and share via the Garmin Dive app.
CUSTOMISABLE DIVE MODES
Add additional screens for each dive mode that features the fields you want to see.
COMPATIBLE WITH INREACH®
Pair with inReach satellite communicators2 and the inReach dive case (each sold separately).
DIVE COMPASS
Easily navigate below the waterline with the built-in 3-axis compass.
TIDE DATA
Stay up to date on ocean conditions so you can catch the perfect wave. Just pair the watch with your compatible smartphone.
SURFLINE®
See conditions — such as tide, wave height, wind and surf rating — for each of the five nearest surf spots, when paired with the Garmin Connect™ app on your compatible smartphone.
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.
You reach new heights. Your watch goes with you.
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.
