The Apple Watch Series 12 is Apple's health-focused smartwatch, sold here in a 42mm pearl white ceramic case with a sand sport band. Its headline is heart sensing: background heart rate every five seconds and HRV readings as often as every five minutes, feeding stress, recovery and readiness insights. It adds hypertension notifications, a daily sleep score, cycle tracking and blood oxygen readings, plus Siri AI and Audio Intelligence. Against rivals it leans on depth of health data and tight iPhone integration rather than battery life, which remains about a day.

Apple Watch Series 12 is a GPS + Cellular smartwatch with a 42mm Pearl White ceramic case and a Sand Sport Band in size M/L. The ceramic case has a sapphire crystal display.
It tracks health and fitness. Heart rate is read in the background every five seconds, and heart rate variability (HRV) is measured as often as every five minutes for insights on stress and recovery. Other health features include hypertension notifications, cycle tracking, a daily sleep score, overnight metrics in the Vitals app, and blood oxygen readings. A readiness feature looks at recent activity, vitals and sleep. For workouts, it offers advanced metrics, Pacer, Heart Rate Zones, and Workout Buddy, which runs on a nearby iPhone with Apple Intelligence.
It can detect a hard fall or severe car crash, connect you with emergency services, and notify your emergency contacts. With cellular, you can make and take calls, stream music and podcasts, and listen with AirPods without your iPhone nearby. Siri AI and Audio Intelligence (Live Rewind and Siri Recap) add voice conversations and help summarizing what you missed. Siri AI is rolling out in English, and some Audio Intelligence features arrive in beta in late 2026.
