Apple Watch Series 7 vs. Apple Watch Series 8 Buyer's Guide: Should You Upgrade?
The Apple Watch Series 8 replaces the Apple Watch Series 7 in Apple's smartwatch lineup, but how different are the two successive smartwatch generations?
In 2021, Apple unveiled the Apple Watch Series 7, including features like taller casing sizes with larger displays, slimmer bezels, improved durability, and faster charging technology. The Apple Watch Series 7 has now been discontinued by Apple, and as year-old models, prices at third-party resellers are falling. As such, some customers may be weighing up whether to upgrade to a Series 7 or a Series 8.
The Apple Watch Series 7 and Series 8 share the overwhelming majority of their features, so should you consider buying or sticking with the Series 7 to save money? This breakdown also serves as a way to see all the differences that the new Apple Watch brings to the table.

Final Thoughts
Overall, the Apple Watch Series 8 is a very minor upgrade over the Series 7, with the body temperature sensor and Crash Detection being the only significant changes, meaning that it is difficult to recommend upgrading. Many Apple Watch Series 7 users will likely not be able to justify upgrading to the Series 8, but some customers coming from an older model could still have good reason to preference the latest models, namely those who do not have an iPhone 14 model with Crash Detection and women who want to take advantage of the cycle tracking features. The Apple Watch Series 8 is very similar to the Series 7, so customers who have an older Apple Watch model and are looking for an upgrade may prefer to look for a discounted Apple Watch Series 7.
