The Apple Watch Series 12 pairs a 42mm aluminum case with a sand-colored Sport Band in size S/M, and its GPS model keeps you connected without carrying your iPhone. Its heart rate sensing measures HRV as often as every five minutes and takes background readings every five seconds, while the Vitals app, daily sleep score, cycle tracking and blood oxygen readings round out its health tracking.

The readiness experience weighs your recent activity, vitals and sleep to help you decide when to rest or push harder, and fitness tools include Pacer, Heart Rate Zones and Workout Buddy powered by Apple Intelligence from a nearby iPhone. Safety features can detect a hard fall or severe car crash and connect you with emergency services and your emergency contacts, and the battery lasts up to 24 hours of normal use with a 15-minute fast charge for up to 12 hours.
