The Apple Watch Series 12 is a smartwatch with a 42 mm gray aluminum case and a navy blue Sport Band in size M/L. It has an OLED touchscreen and runs on the S11 chip. Improved optical and electrical sensors record heart rate at shorter intervals.
It tracks heart rate in the background every five seconds and checks heart rate variability every five minutes, which gives data on stress, recovery and sleep quality. The Vitals app shows overnight health data, and the watch can measure blood oxygen saturation. Apps such as Cycle Tracking and ECG add to its health features. A Readiness score is calculated each morning from recent activity, vitals and sleep, then adjusted through the day.
For workouts, it offers advanced metrics, Pace Target, Heart Rate Zones and a more accurate pedometer. Workout Buddy recommendations use Apple Intelligence on a paired iPhone. Fall detection and crash detection can call emergency services, share your location with them and alert the contacts you have chosen. This GPS model works with your iPhone or a Wi-Fi network to send messages, answer calls, play music, use Siri and show notifications.
