Apple Watch Series 12 launches with more accurate heart rate sensing and a readiness score

Apple 发布 Apple Watch Series 12，搭载全新 Health Sensing System 与 S11 芯片

Apple announced the Watch Series 12, headlined by a new Health Sensing System and S11 chip. It claims the most accurate heart rate sensing in a wearable, with higher-frequency HR and HRV readings that power a new 'readiness score' to tell you if your body is up for a workout. A redesigned Health app later this year adds a Longevity tab and Health Age feature. The S11 chip also enables Audio Intelligence features to remember conversation highlights and alert you to important sounds, processed on-device. watchOS 27 brings Apple Intelligence to the wrist, giving Siri personal context and world knowledge. New finishes include dark bronze and ceramic; aluminum models get Ceramic Shield 2. Pre-orders start today, availability September 18. The post doesn't detail how the readiness score is calculated or whether Audio Intelligence supports Chinese.
