Apple unveils Watch Series 12 with new chip, health sensors and AI audio
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.
