Apple’s next rugged smartwatch could finally be getting its biggest upgrade in years.
According to a new report, the Apple Watch Ultra 4 will receive a major redesign alongside improved health sensors. It sounds like Apple is hoping the changes will reignite interest in its premium wearable.
Since launching in 2022, the Apple Watch Ultra line has mostly stuck to the same chunky titanium look, with only minor tweaks between generations. However, DigiTimes now claims the Ultra 4 will introduce an “all-new” design. This marks the first major visual overhaul for Apple’s top-end smartwatch.
The report does not go into detail about what the redesign actually looks like. Apparently, the changes are significant enough that Apple expects sales to jump by as much as 20 to 30% compared to the previous model. That alone suggests this may be more than just thinner bezels or a slightly different finish.

The bigger story, though, could be the upgraded sensors. DigiTimes claims Apple is planning “significant” improvements to the Ultra 4’s sensor system. These include doubling the number of sensors while also improving power efficiency. As a result, that could mean more accurate health tracking without taking a hit on battery life. Apple Watch Ultra users already care about this more than most smartwatch owners.
At the moment, it is unclear whether Apple is introducing entirely new health features or simply refining existing ones. The report suggests watchOS 26’s high blood pressure alerts could become more reliable on the new hardware. However, proper blood pressure monitoring still does not appear to be ready yet.
The same goes for blood glucose tracking, which has been rumoured for years. Apple is reportedly still working on the feature behind the scenes. However, it is not expected to arrive with the Ultra 4.
Interestingly, this latest leak lands just months after reports suggested the standard Apple Watch Series 12 would receive only modest updates this year. If accurate, it sounds like Apple may instead be putting most of its wearable focus on the Ultra line-up for 2026.
There is still no official launch date. However, Apple will almost certainly unveil the Apple Watch Ultra 4 alongside the iPhone 18 range later this year.
