Apple Watch Gen 4 Series 4 Cell 40mm Space Gray Aluminum - Black Sport Band MTUG2LL/A

Generating your own ECG to save and share with your doctor is just one example of how the Apple Watch is designed to help you monitor your health. It can also detect and monitor your workouts, giving you essential metrics to help you reach your goals. It's water-resistant up to 164', so you can record laps on a track or in the pool. Even when not working out, the Apple Watch utilizes three activity rings to motivate you to keep moving throughout your day.

You can help stay motivated during workouts by streaming your favorite music, podcasts, or invite a friend to a seven-day challenge. In a competition, you'll share your activity and compete for bragging rights and digital medals. Notifications of your friend's progress act like a personal trainer to keep you going.

The Apple Watch Series 4 stays connected to the outside world via Wi-Fi or a wireless Bluetooth connection to your iPhone. When connected, you can use the watch as an extension of your phone to view text messages, interact with Siri, navigate via built-in GPS, or make handsfree calls with the integrated speaker and microphone.
