Apple Watch Series 11 includes 5G and a hypertension tracking feature

Here is a 180-word summary of the key points from the news article: Apple has announced the new Apple Watch Series 11, which includes several new features and improvements. The most notable addition is a hypertension tracking feature that uses the watch's optical heart sensor to monitor for signs of high blood pressure. Apple expects this feature to alert over 1 million people to undiagnosed hypertension in the first year. Other upgrades include a more scratch-resistant screen, a new Space Grey color option, and a battery redesign that allows for up to 24 hours of battery life. Cellular models will now support 5G connectivity. The Apple Watch Series 11 will also introduce new watch faces and a sleep score feature to provide insights on sleep quality. While the design remains largely unchanged from the previous Series 10 model, the pricing starts at $399 for the base 42mm GPS-only version, the same as the outgoing model. The new watches will be available for pre-order today and begin shipping on September 19.
