The new Apple Watch Series 7 was introduced alongside the new iPhones and iPad Minis on September 14th, although Apple has not yet shipped the device. In general, the Apple Watch is always released around the same time as a new iPhone. Thus the delay implied that there were supply constraints at Apple’s end.
The new Apple Watch includes a bigger screen, faster charging, and a new chip than previous models. This model, however, does not have any new health-related features. Last year, the Apple Watch Series 6 included blood oxygen tracking.
The Series 7 of the Apple Watch goes on sale for $399.
