All-new Sensing System
Redesigned optical and electrical sensors work together with larger, more power-efficient green LEDs and the S11 chip to provide higher-frequency heart monitoring. Series 12 can take background heart rate readings every five seconds and measure heart rate variability (HRV) as often as every five minutes, providing richer data for monitoring changes over time.
Understand your readiness and recovery
The new readiness experience analyses recent activity, vital signs, and sleep to provide a simple daily score indicating your capacity for the day ahead. Improved HRV monitoring is incorporated into overnight and daytime vitals, while sleep tracking analyses duration, consistency, awakenings, and sleep stages to provide a detailed sleep score.
Advanced health monitoring
Apple Watch Series 12 supports hypertension notifications by analysing patterns in cardiovascular data over 30-day periods. It also offers ECG, Blood Oxygen, high and low heart rate notifications, irregular rhythm notifications, sleep apnea notifications, advanced Cycle Tracking, and wrist temperature sensing. Availability and intended use of individual health features may vary by region and user eligibility.
More capable fitness tracking
The Workout app supports a wide variety of activities, from running and cycling to swimming, strength training, and badminton. Improved step counting and advanced workout metrics provide a clearer picture of progress, while Workout Buddy can deliver personalised insights and encouragement during supported workouts.
Siri AI and Audio Intelligence
The S11 chip enables new intelligent features directly from the wrist. Siri AI supports more natural conversations and can use broader knowledge and personal context, while Audio Intelligence introduces features such as Sound Recognition and faster Shazam. Live Rewind and Siri Recap are planned for beta release later in 2026, with availability depending on language, region, and a compatible Apple Intelligence-enabled iPhone.
Bright Always-On Retina display
Apple Watch Series 12 is available in 42mm and 46mm case sizes with aluminium, titanium, or ceramic finishes. Its wide-angle Always-On Retina display reaches up to 2000 nits of brightness, helping information remain clear and accessible throughout the day.
Ready for everyday activities
With 50-metre water resistance and IP6X dust resistance, Series 12 is designed for everyday use and activities such as swimming in a pool or ocean. Compatible cellular models support 5G connectivity, allowing calls, messages, and music streaming without relying on a nearby iPhone when supported by the carrier.
Safety when you need it
Emergency SOS provides quick access to emergency services, while Fall Detection and Crash Detection can help contact emergency responders and share your location after a detected serious incident. Apple Pay provides convenient contactless payments directly from the watch.
Up to 24 hours of battery life
Apple Watch Series 12 provides up to 24 hours of normal use on a charge and up to 38 hours in Low Power Mode. Fast charging helps reduce downtime when the battery runs low, making it easier to keep the watch ready for daytime activity and overnight sleep tracking.
