隐私设计
音频智能功能在设计上以隐私保护为核心理念，将硬件、软件和服务相结合，以 Apple 独有的方式保护用户隐私。这些功能不会创建或存储音频录音，用于处理的原始音频对操作系统、App、用户或 Apple 完全不可访问。这是因为 Apple Watch Series 12 上的 S11 芯片包含 Secure Exclave，这是一个专用的硬件隔离区域，在与系统其余部分完全隔离的环境中处理音频，处理后会立即删除。
用户可以完全掌控，并可自行选择是否开启每一项音频智能功能。他们可以精确决定 Siri Recap 在何时何地记录笔记，也可以随时直接从控制中心开启或关闭 Siri Recap。
在设计上，音频智能功能不会识别或标注说话人身份，以保护用户及其周围人的隐私。Siri Recap 生成的是对话的简短、高层面摘要——而非逐字记录——并且设计上会排除敏感信息，如财务信息或政府分配的标识符。Live Rewind 在使用时会发出可听见的提示音，即使 Apple Watch 处于静音模式也不例外，同时会显示全屏动画和麦克风指示器，让周围的人能听到和看到该功能已被激活。
Live Rewind 的文本片段和 Siri Recap 的摘要在 Siri App 中通过 iCloud 同步进行端到端加密，即使是 Apple 也无法访问。
Apple Watch Series 12 offers the most accurate heart rate sensing in a wearable, higher-frequency heart rate and HRV sensing, a readiness score, and Audio Intelligence features built with privacy at the core
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,
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. A redesigned Health app on iPhone arrives later this year, including a new Longevity tab with a Health Age feature showing how metrics are tracking relative to a user’s age. In addition to powering the Health Sensing System, the S11 chip — Apple’s most powerful wearable chip — also enables new Audio Intelligence features arriving later this year, to help users remember key moments from their conversations and stay alert to important sounds, built with privacy, security, and accessibility innovations at the core.
With watchOS 27, Apple Intelligence powers Siri AI on Apple Watch, bringing personal context understanding and broad world knowledge to the wrist.
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,
sleep apnea notifications,
Fall Detection, Emergency SOS,
and more. Apple Watch Series 12 is the most comprehensive wearable across health, fitness, and safety.
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.
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.

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.
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.
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.
