The newly introduced Apple Watch SE is a lower-end version of Apple Watch 6 that lacks blood oxygen monitoring, ECG tracking, always-on display and is only available in aluminum material. Yet, it’s far cheaper and comes with 32GB storage, microphone, loudspeaker, and WatchOS 7 out of the box. The new OS brings new features like Family setup, watch face sharing, cycling map, emoji app while also being a comprehensive health tracker with the ability to track your heart rate, calories, incidental fall detection, and a new sleep tracking feature. Like Watch 6, Watch SE comes in two sizes; 44mm and 40mm, and in this post, I compare the differences between Apple Watch SE 44mm vs 40mm specs and features to help you find out which is a better choice for you.
