It's September, which means the air is thick with the promise of fall, school is back in session, and Apple just revealed a new Apple Watch. This year, at its annual fall event, the company is showing off the Apple Watch Series 9. The Series 9 features a new processor, the S9 chip, and a quad-core neural engine, which promises 18-hour battery life and overall performance boosts. On the software side, watchOS 10 is poised to be the biggest UI overhaul in Apple Watch history, with a renewed focus on widgets, and a slew of app and input updates.

The Series 9 is available to order today and it's due to hit the market on September 22. It starts at $399.
