Apple has unveiled the Apple Watch Series 12 and Apple Watch Ultra 4, headlined by an on-device Apple Intelligence feature that generates automated end-of-day recaps summarizing biometric metrics, workout activity, and key notifications.
Powered by the upgraded S10 System-in-Package, the new lineup leverages localized machine learning models to synthesize health signals—such as HRV, sleep quality, and active stress indicators—into actionable daily debriefs without sending sensitive personal data off-device. The Ultra 4 gains extended 42-hour battery life and multi-band satellite connectivity, while Series 12 introduces a thinner enclosure with enhanced display brightness.
