Apple has unveiled the Apple Watch Series 11, featuring revolutionary hypertension monitoring that works passively in the background using optical heart rate sensors to detect signs of chronic high blood pressure over 30-day periods. The watch also introduces Apple’s first native Sleep Score, providing users with a 0-100 rating based on over 5 million nights of sleep data analysis. Hardware improvements include a more durable, scratch-resistant display on aluminum models and extended 24-hour battery life, up from the previous 18-hour rating. The hypertension feature, pending FDA approval, will also be available on older models including Series 9 and Ultra 2 through the watchOS 26 update. Priced starting at $399, the Series 11 is available for pre-order now with store availability beginning September 19.
