According to reputable sources speaking to 9to5Mac, Apple Watch Series 10 will have more than just bigger screens. This includes an updated ECG/heart rate sensor that will unlock new features and provide more accurate results. One of these features is sleep apnea detection (…) We’ve also heard that Apple is changing how the health data collected by these sensors is processed. This includes using new algorithms in the Health app on the iPhone to look for atrial fibrillation, rather than on the Apple Watch itself. (…) To take advantage of the new screens, Apple will introduce new watch faces. This includes “Reflections,” a watch face that reacts to ambient light. There’s also a new Hermès watch face called “Regatta,” which was created with the sailing sports competition of the same name in mind and will let users easily start a timer right from it. Interestingly, we’ve also heard that Apple will make this new Hermès watch face available for the Apple Watch Ultra, which could be a hint that there will be Hermès bands designed specifically for Apple Watch Ultra. (…) Back to the Apple Watch Series 10, these models will have improved water resistance. (…) Because of this, the Series 10 models will get Apple‘s Depth app, currently exclusive to the Apple Watch Ultra.
