DESIGNED TO RESIST
This rugged dive computer features a 100-meter water resistance rating , a sapphire lens, and meets MIL-STD-810.

DESIGNED TO BE BOLD
With a high-contrast display and bespoke design, this device is built to wow you.

SLEEP SCORE AND ADVANCED SLEEP MANAGEMENT
Get a full breakdown of light, deep, and REM sleep stages. You can see it all in a dedicated widget that includes your sleep score and tips.

MINUTES OF INTENSITY
Track how many minutes of high-intensity activity you´re getting, when you get them, and during what activity. You can even see them as a data field during timed activities.

BODY BATTERY™ ENERGY MONITOR
Monitor your body´s energy levels so you know the best times to do activities and rest.

HYDRATION MONITORING
It allows you to record your daily fluid intake to remind you to maintain a good level of hydration. If you activate the automatic goal, you will be able to see your estimated fluid loss after an activity; the target will be readjusted accordingly.

MONITORING THE MENSTRUAL CYCLE
Use the Garmin Connect ™ app to track your menstrual cycle or pregnancy . Track symptoms, access exercise and nutrition tips, and more.

HEART RATE SENSOR ON THE WRIST
The watch constantly measures your heart rate 4 and alerts you if it remains too high or too low while you´re at rest. It also helps measure the intensity of your exertion during activities, even while swimming.

SUPERIOR MANUFACTURING QUALITY
Enjoy a durable watch-style dive computer with a sapphire lens, silicone straps and an easy-to-read monochrome display.

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