Apple Watch HERMES Series 4 (44MM, Silver, Cellular) - Excellent review
The Apple Watch Series 4 contains the most significant improvements since the Series 2 brought onboard GPS to the smartwatch. Most notable out of all the new features are fall detection and ECG readings, as these have the potential to change people's lives or, quite literally, save them.
Bigger, better screen., All old Watch bands fit on the Series 4., Good battery life., Faster performance., Fall detection has the potential to be lifesaving., ECG features give users more control to monitor their health on a daily basis., Accurate auto workout detection and ending feature.
