Apple Watch Ultra 4 Aims for Health-Sensor Leap and AI Power
Set to debut on Sept. 9, Apple Watch Ultra 4 is rumored to differentiate itself with major health-sensor upgrades (with some reports claiming the sensor components could double) and an FDA-reviewed high blood pressure feature, plus a new high-performance S-class chip (likely S11 or S12) to enable more AI in watchOS 27; design updates are unclear—some reports hint at a redesign while others say no major overhaul, though a ceramic option for Series 12 suggests possible material tweaks for Ultra’s lineup.
