Apple Watch Ultra 4 Rumored to Get Full Redesign and Blood Pressure Monitoring

The Apple Watch Ultra 4 may be shaping up to be one of the more significant updates to Apple’s flagship smartwatch in years. According to a new report from DigiTimes, the next Ultra model could arrive with a complete exterior redesign along with a new blood pressure monitoring feature.

If accurate, the changes would mark a meaningful step forward in both the look of the device and what it can measure on your wrist.

A Closer Look at the Blood Pressure Feature

The headline addition is a new high blood pressure notification system. According to the report, Apple plans to use the optical heart-rate sensor on the back of the watch to study how blood vessels react to each heartbeat. When the device detects an abnormal pattern, it would send the wearer an alert. The feature is said to be undergoing FDA review.

There is some overlap here with a feature Apple already offers, and the report does not fully clarify how the two differ.

Last fall, Apple introduced Hypertension Notifications with watchOS 26. That existing feature also relies on the optical heart sensor, analyzing blood vessel responses over rolling 30-day periods to flag possible signs of high blood pressure.

The new capability described by DigiTimes appears to build on the same underlying hardware. The report suggests that earlier Apple Watch models already had some blood-pressure sensing ability, and that this update represents a more refined or clinically validated version of that technology rather than an entirely new sensor approach.

What Could Come After Blood Pressure

Looking further ahead, Apple’s health ambitions do not stop at blood pressure.

The company’s next major goal is widely expected to be noninvasive blood-glucose monitoring. This is a capability Apple has reportedly been working toward for several years, and like the blood pressure feature, it would depend on government approval before reaching consumers. A reliable, needle-free glucose tracker would be a major milestone for wearable health technology if Apple manages to deliver it.

A Full Redesign for the Ultra Line

Beyond health tracking, the Apple Watch Ultra 4 is also rumored to receive a substantial visual overhaul.

This is not the first time such a redesign has surfaced. A DigiTimes report from last year claimed that at least one new Apple Watch model would feature a significant redesign, with supply chain sources describing exterior changes that include eight sensors arranged in a ring pattern on the back of the watch.

The latest report goes further, describing the update as a full redesign paired with a significant upgrade to the device’s sensing functions. In other words, both the appearance and the internal sensing hardware could see notable changes.

Why the Redesign Matters for Apple

A refreshed design could do more than please longtime fans. According to market observers cited in the report, the new look and upgraded sensors could lift Apple Watch shipments by 20 to 30 percent compared with 2025.

There is a supply chain angle as well. The sensor upgrades are expected to be a significant win for Taiwan-Asia Semiconductor, described as Apple’s exclusive supplier of sensor components. Large-volume orders for those parts could begin as early as July, which would be an early sign that production is ramping up.

When to Expect the Apple Watch Ultra 4

The Apple Watch Ultra 4 is expected to make its debut in fall 2026. It would not arrive alone. The watch is anticipated to launch alongside several other major products, including:

• The Apple Watch Series 12
• The iPhone 18 Pro and iPhone 18 Pro Max
• A foldable model rumored to be called the “iPhone Ultra”

A Note of Caution

As with all pre-release reports, these details should be treated as rumors rather than confirmed facts. DigiTimes has a mixed track record, and Apple has not announced anything official about the Ultra 4, its design, or its health features.

Still, the latest report lines up reasonably well with earlier rumors about a redesigned Apple Watch, which adds some credibility to the overall direction. If the blood pressure monitoring clears FDA review and the redesign materializes, the Apple Watch Ultra 4 could turn out to be one of the more compelling reasons to upgrade when Apple’s fall 2026 lineup arrives.
