Apple Watch Series 10

The Apple Watch Series 10 (2024) is the slimmest Apple Watch ever made, featuring a 1.96-inch wide-angle LTPO OLED always-on display in a case just 9.7mm thick. Powered by the Apple S10 chip and running watchOS 11, it works exclusively with iPhone and integrates deeply with Apple Health and Apple Fitness Plus. The titanium or aluminum case comes in 42mm and 46mm sizes. Health sensors include optical heart rate, FDA-cleared ECG, blood oxygen (SpO2), and skin temperature monitoring. The headline addition is FDA-authorized sleep apnea detection, which tracks breathing disruptions across multiple nights and flags patterns consistent with moderate to severe sleep apnea. Precision dual-frequency GPS (L1 and L5) delivers accurate outdoor route tracking, while WR50 (50-meter) water resistance covers pool swimming and open-water activities. The Series 10 offers 60-plus workout types, Crash Detection, Fall Detection, and onboard Apple Pay. Battery life of 18 hours in standard mode remains the main constraint, requiring nightly charging, though Low Power Mode extends runtime to 36 hours. For iPhone-centric users who train several days per week and want seamless health data aggregation with the most polished wearable software, the Series 10 is the definitive all-in-one fitness and wellness tracker.
