Apple Watch Series 12 is a GPS smartwatch and health and fitness tracker with a 42mm black aluminum case and a black Sport Band in size S/M. Its heart rate sensing measures HRV as often as every five minutes and takes background heart rate readings every five seconds. The Vitals app shows overnight health metrics, and the watch provides a daily sleep score, cycle tracking, blood oxygen readings and hypertension notifications.
For fitness, it offers advanced workout metrics, Pacer, Heart Rate Zones and a readiness experience that analyzes recent activity, vitals and sleep. Workout Buddy is powered by Apple Intelligence from a nearby iPhone. The watch can detect a hard fall or severe car crash, help connect you with emergency services and notify your emergency contacts.
The aluminum case has Ceramic Shield 2 glass. The GPS model works with your iPhone or Wi-Fi to send texts, take calls, play music, use Siri and show notifications. Battery life is up to 24 hours of normal use, and a 15-minute fast charge gives up to 12 hours of normal use.
