The only thing truly new about last year's Apple Watch Series 6 was the addition of estimated blood oxygen.
The larger screen should allow more readable and detailed watch faces, notifications and apps, much like the Series 4's size increase a few years ago.Apple says it's 20% larger than the Series 6, and 50% larger than the Series 3.
There are new watch faces, too: a revamped Modular watch face and a number-warping watch face with its digits around the curved edge.Samsung's recent Galaxy Watch 4 and last year's Fitbit Sense started introducing new health sensors like body analysis and electrodermal activity, but Apple hasn't introduced anything new on the Series 7 health-wise compared to last year.
Also absent is any improvement in battery life or a watch face store.
The Apple Watch Series 7 starts at $399, but we don't know prices for the different sizes, LTE-ready models, or for different materials.Last year's Apple Watch SE sought to become a more affordable Apple Watch, but its $279 starting price was still well above budget fitness trackers from companies such as Fitbit
