The Newest Apple Watch – Apple Watch Series 7

The Apple Watch Series 7 was made available to order beginning this past Friday, October 7, 2021 and will be available in stores starting October 15.

The Apple Watch 7 features the largest and most advanced Apple Watch display ever which includes a brighter Always-On Retina display with significantly more screen area and thinner borders. Users benefit from the same all-day 18-hour battery life with 33 percent faster charging.

But how does the new Series 7 compare to earlier models of the Apple Watch?

The Design of the Apple Watch Series 7

Apple-Watch-7-watchfaceApple describes the design of Apple Watch Series 7, which is available in 41mm and 45mm sizes, as “refined with softer, more rounded corners, and the display has a unique refractive edge that makes full-screen watch faces and apps appear to seamlessly connect with the curvature of the case. At just 1.7 mm thin, the narrower borders of Apple Watch Series 7 maximize the screen area of the display while minimally changing the dimensions of the watch itself.”

User Interface of the Apple Watch Series 7

Our recommendation

The most compelling improvements of the Apple Watch Serie 7 are the larger screen, the faster charging, the improved durability and the onscreen keyboard. If one or more of these features are important to you then you should consider upgrading.

If you just want to have the latest and greatest AND you have someone who would love to have your “old” Apple Watch then go for it – you won’t be sorry and you’ll make someone else happy!
