The Apple Watch Series 9 is the first carbon-neutral Apple product, using recycled materials and reducing carbon footprint through ocean shipping.
The Series 9 is smarter with a more powerful S9 chip, brighter with a screen that reaches 2000 nits, and mightier with new gesture control and features.
The design is similar to Series 7 and 8, but the watch feels lighter, and the sports loop strap offers a snug fit.
The WatchOS UI has scrollable notification widgets and some new features that make life easier.
Workouts provide better data and are easier to understand, including data on workout zones.
The find my phone feature offers step-by-step directions, similar to AirTags.
The Series 9 has a faster processor (S9) and upcoming double tap control feature for apps.
Interoperability between Apple devices is improved, with a now-playing widget for HomePod.
The battery life has improved, lasting well over a day without cellular usage and extending to a second evening with low power mode.
