Apple Watch Series 12 adds S11 chip, upgraded health sensors, ceramic models
Apple announced the Apple Watch Series 12 with a new S11 chip, redesigned health sensors, and new aluminum, titanium, and ceramic finishes, starting at $399 with preorders available today. The Series 12 features a larger ECG electrode surface, ring-arranged photodiodes, and efficient green LEDs for more accurate heart rate tracking. A new Readiness feature scores daily recovery, while the redesigned Health app adds AI-powered guidance and a Health Age metric. The S11 chip enables Audio Intelligence features like Sound Recognition and Siri Recap, which generates conversation summaries without storing recordings. Availability begins September 18, with the redesigned Health app launching later this year.
