Apple Watch Ultra 4 is the health story that got buried under the foldable. Officially on sale since September 18 at $799 in natural or black titanium, it pairs the S11 chip with a Health Sensing System Apple calls its most accurate heart-rate setup in a wearable, plus a readiness score and up to 50 hours of battery. Series 12 landed the same day, bringing ceramic back in pearl white and night blue from $899. Live Rewind and Siri Recap still sit in a later beta and stay off EU watches at launch.
