Connectivity and Sensors
For connectivity, the watch supports Wi-Fi b/g/n, Bluetooth 5.0 with A2DP and LE, and NFC, enabling Apple Pay and other near-field communication processes. Notably absent are radio and USB capabilities, typical omissions in Apple Watch designs. The Apple Watch SE is equipped with a comprehensive array of sensors, including an accelerometer, gyro, second-generation heart rate monitor, barometer, always-on altimeter, and compass, enhancing its utility for fitness and navigation tasks.
