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.

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, plus intelligence features that make everyday life easier. 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.

Apple Watch Series 12 features larger, power-efficient green LEDs on the optical heart sensor, measuring heart rate every five seconds and delivering deeper insight into a user’s fitness and physiological state.

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.

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 life

and now offers up to 10 hours of battery life during an outdoor workout — 25 percent more than the previous model.

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.

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.

The S11 chip also enables the brand-new Steps complication, so users can track their steps in real time, right from their watch face.

A Redesigned Health App Offers a Holistic View of Long‑Term Health

The Health app on iPhone serves as a central and secure location for a user’s health and fitness information, uniquely positioning it to provide a better understanding of a user’s health. The Health app has been redesigned to dynamically respond to a user’s data using Apple Intelligence,

with a new Insights tab that surfaces timely health information and a new Longevity tab that analyzes a user’s longitudinal health data for deeper insights. The Longevity tab includes Health Age, an Apple Watch feature that shows users how certain metrics are tracking relative to their actual age.

The Health app also includes movement evaluations that measure flexibility, strength, balance, and more using vision-based AI models on iPhone and heart rate data from Apple Watch. Users will be able to schedule and purchase new labs that feature over 50 key biomarkers for $119 directly through the Health app at approximately 2,000 Quest Diagnostics locations in the U.S. The redesigned Health app will arrive later this year, starting in U.S. English.

Audio Intelligence: A New Way to Stay More Present and Engaged Throughout the Day

Since Apple Watch is always on a user’s wrist, it is the perfect device to help users stay alert to important sounds and stay present and engaged in conversations throughout the day. With the built-in microphone, the power of the S11 chip, the latest Apple Intelligence models on iPhone, and Private Cloud Compute, Apple Watch Series 12 offers a brand-new class of Apple Intelligence features. Audio Intelligence helps users stay aware of the world around them, catch what they missed, and remember key moments — with user control, privacy, security, and accessibility at the center of its design.

Audio Intelligence 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.

Live Rewind, which can help users recall what was just said in conversation. A double press of the Digital Crown shows the previous 15 seconds of a conversation as a text snippet, so the user can catch something they may have missed or are less familiar with. Users can ask Siri about the content of the text or save it to the Siri app to revisit later.

Siri Recap, which can create high-level summaries of conversations that users can review later to jog their memory. When Siri Recap is turned on, after a conversation, Apple Intelligence automatically generates a title and key points in the new Siri app, allowing users to be more present and engaged in the moment.

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.

Privacy by Design

Audio Intelligence 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.

Users are in control and can choose whether to opt in to each Audio Intelligence feature. They can decide exactly where and when Siri Recap takes notes, and can turn Siri Recap on or off at any time, right from Control Center.

By design, Audio Intelligence features do not identify and attribute speakers, to protect the privacy of both the user and those around them. Siri Recap produces a brief, high-level summary of conversations — not a transcript — and is designed to exclude sensitive information like financial information or government-assigned identifiers. Live Rewind plays an audible chime when it is being used, even if Apple Watch is on silent, and shows a full-display animation and microphone indicator so people nearby can hear and see that the feature has been activated.

Live Rewind text snippets and Siri Recap summaries are end-to-end encrypted in the Siri app with iCloud syncing, and are not accessible even by Apple.
