Apple Watch Series 5 features an Always-On Retina display, built-in compass and international emergency calling. The Always-On Retina display never sleeps, so it’s easy to check the time and other important information. It offers a new way to show location features, from a built-in compass to current elevation, as well as international emergency calling, even without an iPhone nearby.

You have ECG on your wrist, low and high heart rate notifications, fall detection and emergency SOS, and new Breathe watch faces. It is designed to improve your health every day and powerful enough to help protect it.

Apple Watch Series 3 is packed with smart technology. You can receive messages and stream music. The GPS and Altimeter allows you to see how far and how high you go. Watch is swimproof so you can jump into the pool or ocean any time you want.
