Stay connected, stay informed, and remain healthy with the Apple Watch Series 4. This Apple Watch features a 40mm curved watch face with an LTPO OLED Retina display and digital crown. The crown is how you navigate through watchOS 5 to view your apps and content. The crown has haptic feedback, giving each turn a mechanical click-like feel, and an integrated titanium electrode lets you use the ECG app. On the back, the Apple Watch features an optical heart sensor to quickly check your heart rate, and an electric heart sensor that works with the crown to generate an ECG (electrocardiogram).
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 with Nike apps and exclusive watch faces, such as the Nike Run Club and Nike Training Club. The Nike Run Club app features audio-guided runs every week with the voice of a guest coach, a curated soundtrack, detailed in-run metrics, and even custom cheers. The Nike Training Club app provides over 180 free workouts from world-class Nike Master Trainers. It will even notify you with workout recommendations that you can do to close your exercise ring for the day.
The Apple Watch Series 4 stays connected to the outside world via Wi-Fi or a wireless Bluetooth connection to your iPhone. With cellular support, you can leave the phone at home and do it all through your Apple Watch. No matter how you connect, you can use it to monitor text messages, interact with Siri, use the built-in GPS to navigate around town, or simply make calls handsfree with the integrated speaker and microphone.
