Apple Watch Series 3

Fit. Healthy. Connected.
Monitor your health. Track your workouts. Get the motivation you need to reach your fitness goals. Stay connected with the people you care about and get updates on what matters to you. With Apple Watch Series 3, you can do it all, right from your watch.

Three rings. One goal.
The Move, Exercise, and Stand rings show you how much you're moving each day, so you know if you've been spending too much time at your desk, how many calories you've burned, and how many minutes of exercise you've gotten. You can also share your rings with friends, try new Activity challenges, and train smarter with a virtual coach to encourage you whenever you need it.

When the going gets tough.
Yoga, cycling, swimming, HIIT cardio—now you can track everything you do.1 Advanced runner features like cadence tracking and pace alerts help you track your runs even more efficiently. When you're at the gym, you can pair your watch with compatible machines.2 And with Apple Music and Apple Podcasts streaming, you can find instant motivation.

The body always in mind.
Your heart is always under control: if your heart rate is higher or lower than normal, the watch sends you an alert, and if it's time to call for help, the Emergency SOS function is ready to lend a hand. The Breathing app is a valuable aid in managing daily stress. And there are plenty of health apps to choose from: you're sure to find the ones best suited to your habits and specific goals.

Freedom calls.
Take a call while you're on the water, ask Siri to send a message, stream your favorite music while you run, or use Emergency SOS to call for help, even if you left your phone at home. With built-in cellular connectivity, if you have your watch on your wrist, you're all you need.
