If you were hoping for a radical new Apple Watch design or a plethora of new features, 2023 won't be your year. That said, the Apple Watch Series 9—which was just announced in Apple's September livestream—brings some welcome if modest tweaks to the popular wearable.

The most notable of these is the inclusion of the new S9 chip, which promises improved performance—but more importantly, better battery life. It promises 60% more transistors in its CPU than the Series 8, and 30% more in its GPU. Perhaps most importantly, its neural engine promises big boosts to on-device processing for Siri requests, including 25% faster voice dictation.
