Apple’s 2026 Watch Ultra 4 is set for its first major redesign since 2022, with a titanium case estimated to be about 15% slimmer than the Ultra 3.
Eight rear sensors in a new ring layout would double the current sensor count, shifting more health tracking from algorithmic estimation toward direct measurement.
Blood pressure monitoring is the headline addition: the watch would use its optical heart-rate system to flag abnormal hypertension patterns rather than provide exact cuff-style readings, and the feature is under FDA review.
Taiwan-Asia Semiconductor, Apple’s exclusive Ultra sensor supplier, expects large-volume orders as early as July 2026, while observers say the overhaul could lift Apple Watch shipments 20% to 30% from 2025 levels.
Apple is expected to unveil the Ultra 4 in the second half of 2026, likely around its September event, with pricing still seen near the Ultra line’s longstanding $799 launch point.
