The upcoming Apple Watch Ultra 4 will feature advanced health sensors designed to detect signs of hypertension by analyzing blood vessel dilation through green and infrared LEDs, according to reporting by Bloomberg’s Mark Gurman. Expected to debut at an Apple event in September 2026, the new wearable will utilize these optical sensors to track vascular changes beneath the skin, marking a significant step forward in consumer health monitoring for smartwatches.
Health Tracking and Hypertension Detection
According to Bloomberg reporting by Mark Gurman, the Apple Watch Ultra 4 relies on a specialized array of green and infrared LEDs that shine light through the wearer’s skin. This system analyzes how blood vessels dilate to spot early indicators of high blood pressure. This capability positions the upcoming device alongside modern health-focused wearables like Samsung’s Galaxy Watch 7 and Xiaomi’s Smart Band 10 Pro, both of which emphasize detailed sleep and physical tracking metrics.
Hardware Upgrades and Design Expectations
Beneath the exterior, the Apple Watch Ultra 4 will house a new processor, anticipated to be branded as the S11 or S12 chip, according to Bloomberg’s Mark Gurman. This updated silicon will reportedly integrate Apple’s artificial intelligence-powered Siri features. However, buyers should not expect a major physical redesign. Gurman reports that Apple plans to keep the exterior largely unchanged for its smartwatch lineup launching in 2026, bypassing any major aesthetic overhaul for this hardware generation.
Release Timeline
The unveiling is scheduled to take place at the company’s event on September 7, 2026, where further specifications regarding its processing power and health capabilities will be officially detailed.
