Apple Watch Series 12 Review: Finally, a Readiness Score (2026)

Apple’s Series 12 runs on a faster S11 chip and includes a new Health Sensing System that increases metric frequency and breadth, a Readiness score, and Audio Intelligence powered by Apple Intelligence. The watchOS 27 update streamlines the interface, centers Siri AI, and adds a 24-hour battery with 15-minute fast charging for 12 hours of life. Ceramic finishes return in pearl white and night blue. Aluminum and titanium models are 9.7 mm thick, and the aluminum line now features a 60% tougher Ceramic Shield 2.
