The Apple Watch Series 10 and Ultra 2 also have some commonalities with respect to the health and fitness features. Each of them retains a temperature sensor, ECG application, heart rate notifications for extremes, as well as heart rhythm variations. Nevertheless, as a result of a patent dispute in the United States, the newly introduced Ultra 2 or Series 10 watches will not be equipped with the blood oxygen sensor. A deeper analysis of the Ultra 2 comes with more specifications such as an 86 dB siren, a greater operating range, a depth gauge of 40 meters, and dual-frequency GPS for better tracking in areas with a lot of buildings.
