Apple on 9 September 2026 announced Apple Watch Series 12 and Apple Watch Ultra 4, with Singapore prices on apple.com/sg from S$599 for Series 12 aluminium and S$1,199 for Ultra 4.
Both watches sit in Apple’s first-wave markets. Pre-orders are open on the Apple Store online, with retail availability from Friday 18 September 2026.
Health Sensing System and readiness
Series 12 and Ultra 4 share Apple’s new Health Sensing System and the S11 chip. Apple says the system delivers the most accurate heart rate sensing in a wearable, with higher-frequency heart rate and heart rate variability measurements.
Those readings feed a new readiness score. Each day the watch gives a 0 to 10 score plus one of four prompts: Recover, Pace Yourself, Ready, or Go For It. Apple bases the score on recent activity, vitals and sleep score.
With watchOS 27, Apple Intelligence powers Siri AI on Apple Watch, bringing personal context and broader world knowledge to the wrist. Audio Intelligence features, built around privacy and accessibility, arrive later this year on the S11 hardware.
