Apple Watch features and health monitoring capabilities

Apple's smartwatch lineup offers varying levels of health monitoring and hardware specifications. The Apple Watch SE 3 serves as a more affordable entry point at $249, featuring an Always-On display, fast charging, wrist temperature sensing, and sleep apnea notifications. While it lacks the larger screen real estate of premium models, it includes core fitness tracking, fall detection, and crash detection.

The Series 12 provides advanced capabilities, including a larger and brighter display with up to 28 percent more area than the SE 3, a new Health Sensing System, and enhanced heart-health features.

Beyond specifications, the devices have demonstrated utility in detecting medical irregularities. Users have reported the watches successfully flagging irregular heartbeats via ECG sensors, which has assisted in identifying potentially life-threatening heart conditions and providing early warnings for health issues.
