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.
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.
This metric evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching.
For training guidance that takes you and your fitness level into account, get daily run suggestions based on your current training load and status.
Track how you’re breathing throughout the day, during sleep, and during breathwork.
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.
Track your body’s energy levels so you can find the best times for activity and rest.
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.
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.
Enjoy a rugged, watch-style dive computer with a sapphire lens, silicone bands and an easy-to-read monochrome display.
Receive emails, texts and alerts right on your wrist when paired with a compatible device.
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.
