The Apple Watch Series 10 Has a Whole New Look

This year marks the 10th anniversary of the Apple Watch, the top-selling rectangular wearable that can be seen on the wrists of millions of iPhone owners. As befits a landmark anniversary, this year's flagship Apple Watch 10 has gotten an updated design that is much thinner and lighter than the previous Watch Series 9, along with a new, jet black finish. Every year, Apple adds new health features to the watch. This year, that feature is sleep apnea detection. The most highly anticipated health feature was tracking for hypertension, or high blood pressure, and that has not shown up on the Apple Watch yet--probably because earlier this year, Apple was ordered to stop selling watches with blood oxygen sensing because of a patent dispute with Masimo Corp.
