Apple unveiled the Watch Series 12 at its event in Cupertino, California, highlighting an upgraded S11 processor, doubled RAM, a redesigned sensor array with higher-frequency health monitoring, faster charging and a suite of on-device AI audio features, including Live Rewind, Siri Recap, conversation summarization and short-term transcription. Earlier leaks, reported by 9to5Mac, indicated the Series 12 would debut a new chip and health sensor, and CNET noted Apple planned to launch an Ultra 4 model alongside it. Beta code for watchOS 27 suggested a Readiness app, expanded strength-training data and up to 128 GB storage, according to MacRumors, a detail echoed by a separate watchOS 27 leak reported by 9to5Mac.
