CUPERTINO, CALIFORNIA Apple today introduced Apple Watch Series 12, engineered with advanced health sensors and all-new Apple silicon to deliver the most accurate heart rate sensing in a wearable,1 and advanced health and fitness features.
With the new Health Sensing System and S11 chip, Apple Watch Series 12 delivers higher-frequency heart rate and heart rate variability (HRV) measurements, which power an enhanced suite of health and fitness features including a new readiness score. In addition to powering the Health Sensing System, the new S11 chip — Apple’s most powerful wearable chip — also enables new features arriving later this year, to help deaf or hard of hearing users stay alert to important sounds, with privacy, security, and accessibility innovations at the core. 
These features add to the many ways Apple Watch already helps users stay active, better understand their health, and get help when they need it, with advanced workout tracking, sleep tracking, heart health notifications, the ECG app,2 sleep apnea notifications,3 Fall Detection, Emergency SOS,4 and more. Apple Watch Series 12 is the most comprehensive wearable across health, fitness, and safety.5,6
Apple Watch Series 12 is designed to be as individual as the person wearing it and is available in an array of beautiful finishes, including dark bronze, black, light gold, and space gray aluminum, and radiant gold and natural titanium. It is also available in a stunning ceramic material, in pearl white and night blue. Aluminum models now feature Ceramic Shield 2, which is tougher than any smartwatch glass and 60 percent tougher than the Ion-X of previous aluminum models.7 Apple Watch Series 12 is available to pre-order today, with availability beginning Friday, September 18.
“Apple Watch Series 12 is the most advanced health and fitness companion we’ve ever created,” said Kaiann Drance, Apple’s vice president of Worldwide Apple Watch Product Marketing. “With our new Health Sensing System and S11 chip, Apple Watch Series 12 gives you meaningful insights, like readiness, so you can better understand how to take on your day and care for your health. And it’s all wrapped in a beautifully thin, light design you’ll love wearing all day and night.”

The Most Accurate Heart Rate Sensing in a Wearable

Apple Watch Series 12 is re-architected to provide continuous high-fidelity health monitoring using the Health Sensing System, featuring new optical and electrical heart sensors. Using this system and the S11 chip, Apple Watch Series 12 offers the most accurate heart rate sensing in a wearable. A scientifically rigorous study on a diverse population of over 1,000 participants compared the new heart rate sensing accuracy on Apple Watch against leading wearables, resulting in Apple Watch showing the highest accuracy across devices.
With larger, power-efficient green LEDs on the optical heart sensor, Apple Watch Series 12 now measures heart rate every five seconds, all day long. This continuous, passive measurement delivers deeper insight into a user’s fitness and physiological state while making Exercise and Move Activity rings even more accurate. Users can view their real-time heart rate at a glance throughout their day on a new heart rate watch face complication.

HRV, a key indicator of stress and recovery, is now measured up to 24 times more often and available to view in a new section of the Heart Rate app. Apple Watch provides two separate variants of HRV for better understanding of a user’s health status. Recovery HRV is best for identifying daily signals of stress and recovery, while overall HRV is best for insights into a user’s broader health, including cardiovascular health. Higher variability is generally associated with better overall recovery, while a lower variability value is an indicator of stress.
Overnight vitals now includes recovery HRV measurements analyzed against a user’s personal baseline, providing a more complete view of their health status.15 A new daytime vitals view lets users toggle between overnight and daytime metrics, and can potentially spot shifts in their metrics before they show up overnight.

Readiness: A Daily Read on the Body’s Capacity

Apple Watch Series 12 introduces readiness, a new feature that analyzes a user’s recent activity, training load, vitals, and sleep score to offer insight into their capacity for the day ahead. Readiness provides a single 0-10 score with a clear, actionable recommendation: Recover, Pace Yourself, Ready, or Go For It. This helps a user decide how to take on their day, whether they’re headed into a workday or tackling their training plan.
Readiness updates throughout the day as new data comes in, to reflect, for example, an intense workout or a shift in daytime vitals. Readiness clearly highlights which factors are driving the score and allows users to tap into more details. The scoring algorithm was developed using data from the Apple Heart and Movement Study, in collaboration with exercise scientists and physicians at Apple.

Readiness analyzes a user’s recent activity, training load, vitals, and sleep score, and then provides a single 0-10 score each day with a clear, actionable recommendation: Recover, Pace Yourself, Ready, or Go For It.

Longer Workout Battery Life and Faster Charging

Apple Watch Series 12 continues to offer up to 24 hours of everyday battery life9 and now offers up to 10 hours of battery life during an outdoor workout — 25 percent more than the previous model.10
Apple Watch Series 12 also offers faster charging: Just 15 minutes now gets up to 12 hours of additional battery life — 50 percent more than the previous model — so users can quickly recharge while getting ready for the day or before bed.11

The Most Accurate Step Tracking of Any Smartwatch

The pedometer model has been completely redesigned with new machine learning algorithms to provide more accurate distance measurements during indoor walk or run workouts, and the S11 chip allows for more accurate step counts all day. As a result, Apple Watch Series 12 now offers the most accurate step tracking of any smartwatch.12 The S11 chip also enables the brand-new Steps complication, so users can track their steps in real time, right from their watch face.

Sound Recognition and Shazam Using the S11 Chip

Since Apple Watch is always on a user’s wrist, it is the perfect device to help users stay alert to important sounds. With the built-in microphone and the power of the S11 chip, Apple Watch Series 12 offers new features to help users stay aware of the world around them — with user control, privacy, security, and accessibility at the center of its design.
These features include:
  • Sound Recognition, which comes to Apple Watch to alert users who are deaf or hard of hearing of important sounds, even when their iPhone isn’t with them. This feature listens for sounds like sirens, alarms, doorbells, or a baby crying, and uses on-device intelligence to notify users when they’re detected.
  • Shazam, which instantly detects the music playing around the user and automatically displays the song title and artist’s name on the Music Recognition widget in the Smart Stack, easily glanceable on the wrist.
These features are private by design, combining hardware, software, and services to protect user privacy in a way that only Apple can. These features do not create or store audio recordings, and raw audio used for processing is completely inaccessible to the operating systems, apps, the user, or Apple. This is because the S11 chip on Apple Watch Series 12 includes Secure Exclave, a dedicated hardware-isolated compartment that processes audio in complete isolation from the rest of the system, then immediately deletes it.

Featuring watchOS 27

watchOS 27 brings a range of additional updates to Apple Watch Series 12, including:
  • Sleep apnea notifications on Apple Watch arrive in the Philippines to help identify signs of moderate to severe sleep apnea. Every 30 days, breathing disturbance data is analyzed and the user will be notified if it shows consistent signs of moderate to severe sleep apnea so they can speak to their doctor about next steps, including potential diagnosis and treatment.
  • A dynamic app grid featuring the icons for five Siri-suggested apps, which are a user’s most-used and recently used Apple Watch apps.
  • A new single-handed tap gesture, which lets users conveniently open a widget in the Smart Stack by tapping their index finger and thumb. Now users can use the double tap gesture to scroll through the Smart Stack and single tap to select an individual widget — all using only one hand.14
  • Smart Stack widget suggestions, which surface when they are most relevant, like a Parked Car suggestion from Maps or a Birthday Message suggestion on a close contact’s birthday.
  • Support for perimenopause and menopause in Cycle Tracking on Apple Watch and in the Health app on iPhone.15
  • Support for Workout Buddy on Apple Watch when users don’t have their iPhone nearby. Workout Buddy also now incorporates even more fitness data when delivering motivational insights, and is now available in Spanish in addition to English.16
