Apple Watch SE features a stunning Retina display, with thin borders and curved corners, that is 30 percent larger than Series 3. The interface allows for large and easy-to-read app icons and fonts, while complications are precise and informative. A variety of new watch faces are optimized for the display, so customers can easily view notifications, text messages, workout metrics, and more.

With the S5 System in Package (SiP) and dual-core processor, Apple Watch SE delivers incredibly fast performance, up to two times faster than Apple Watch Series 3. The Digital Crown with haptic feedback generates incremental clicks with an extraordinary mechanical feel as it is rotated. Apple Watch SE features the latest speaker and microphone, which are optimized for better sound quality for phone calls, Siri, and Walkie-Talkie, along with Bluetooth 5.0.

• Advanced Fitness Features

The next-generation always-on altimeter provides real-time elevation all day long by using a new, more power-efficient barometric altimeter, along with GPS and nearby Wi-Fi networks. This feature allows for the detection of small elevation changes above ground level, up and down to the measurement of 1 foot, and can be shown as a new watch face complication or workout metric.

The built-in compass provides users with better directions and compass headings, in addition to incline, elevation, and latitude and longitude. Users can add one of three new Compass complications to their watch face, and developers can take advantage of compass information in their apps to create rich experiences.

• Health and Safety

With Emergency SOS on Apple Watch, customers can quickly and easily call for help and alert emergency services with just a push of a button. For added personal safety while traveling, users with cellular models of Apple Watch SE can complete international calls to emergency services, regardless of where the device was originally purchased or if the cellular plan has been activated.

Fall detection uses a custom algorithm and the latest accelerometer and gyroscope in Apple Watch SE to detect when a user falls. By analyzing wrist trajectory and impact acceleration, Apple Watch sends the user an alert after a hard fall, which can be dismissed or used to initiate a call to emergency services. If the watch senses immobility for approximately 60 seconds after the fall, it will automatically call emergency services and play an audio message that provides the user’s location as latitude and longitude coordinates, in addition to sending a message to emergency contacts.

To provide enhanced insights into hearing health, Apple Watch SE utilizes the latest-generation microphone to measure ambient sound levels in a user’s environment. Apple Watch SE sends a notification if the decibel level of surrounding sound has risen to a point that it could cause damage, and users can check noise levels at any time through the Noise app or Noise watch face complication.
