Apple Watch Series 12 (GPS) is a smartwatch and health and fitness tracker with a 42mm light gold aluminum case and a Sand Sport Band in size M/L. It measures heart rate and also takes HRV readings as often as every five minutes for insights on stress and recovery. Background heart rate readings are taken every five seconds.
For health, it offers the Vitals app for overnight metrics, a daily sleep score, cycle tracking, hypertension notifications and blood oxygen readings. A readiness experience analyzes recent activity, vitals and sleep. For fitness, it has Pacer, Heart Rate Zones, advanced workout metrics and Workout Buddy, which is powered by Apple Intelligence from a nearby iPhone.
It can detect a hard fall or severe car crash, help connect you with emergency services and notify your emergency contacts. It works with your iPhone or Wi-Fi to send texts, take calls, play music, use Siri and show notifications. The aluminum case has a Ceramic Shield 2 display. Siri AI and Audio Intelligence features, including Live Rewind and Siri Recap, are available in English first. Some Audio Intelligence features arrive in beta in late 2026.
