GoKawiilApple Watch Ultra 4 rumored to double sensors and get new S-class chip
Ahead of a September 9 unveiling, reports suggest Apple Watch Ultra 4 will feature substantially upgraded health sensors, with Digitimes claiming the number of sensor components could double, alongside a new blood pressure-related feature reportedly under FDA review.

GoKawiil's interpretation of the reporting above, not reported fact.
A faster chip arriving alongside Siri's AI overhaul in watchOS 27 suggests Apple wants the Watch to become a leading AI-capable wearable, not just a fitness tracker. Meanwhile, deeper health sensing—especially blood pressure monitoring—could be a major differentiator in a wearables market increasingly focused on medical-grade features.
- Sensor components may double, enabling advanced health tracking including possible blood pressure monitoring.
- A new S11 or S12 chip would be the first major performance boost since 2023, timed with Siri AI upgrades.
- Design changes remain uncertain, with conflicting reports on whether Ultra 4 gets a full redesign.
