It’s Missing Vital Features

Apple has also made a lot of hardware improvements to the Series 7, including some of the best features the Apple Watch has and reasons why some people buy one in the first place. Take the ECG readings to monitor heartbeat, for example. That much-praised feature showed up in the Series 4 – so, you don’t get it with the Series 3. Or take the Blood Oxygen app that became particularly popular during COVID: that was only available starting with the Apple Watch Series 6. Other hardware improvements have enabled new modes, improve data connections to cell towers, and lots more. Choosing the Series 3 skips out on all those improvements.
