Apple has locked in September 9 as the date for its next big hardware reveal. As per reports, Apple Watch Ultra 4 sits near the top of the list. Multiple reports paint a picture of the most substantial Ultra upgrade since the line launched back in 2022. Let’s check what is happening, touching everything from internal sensors to the chip driving the whole experience.
Health tracking looks set for its biggest jump yet. Supply chain reporting points to a doubling of sensor components inside the Ultra 4. As reported by Digitimes, there could be up to eight sensors arranged around the back of the device. That shift would move Apple away from algorithm-based estimates toward more direct physical measurements. For things like heart rate, blood oxygen, and skin temperature, this would be a massive upgrade. Blood pressure monitoring appears to be part of that push too, reportedly using an optical heart-rate sensor to flag abnormal patterns. Reports suggest the feature has already gone through FDA review ahead of a possible release. Apple’s longtime sensor supplier is also said to be ramping up large-volume production heading into the second half of the year.
Not just the sensors, Processing power gets a real refresh too. The Apple Watch chips barely moved the needle on performance for years. Recent Apple Watch models have used the same core chip since 2023. Reports from Gurman Bloomberg now point to a brand-new processor. It will likely be called the S11 or S12. Apple built this new chip specifically for an AI-powered Siri. watchOS 27 arrives this fall with a much smarter assistant. A stronger chip gives Siri the power it needs right on your wrist. That extra power keeps the watch running fast without any lag.
Design remains the messiest part of the story, with reporting split into two clear camps. One side describes a full redesign, including a titanium case that runs noticeably thinner than the current model. The other camp, backed by well-connected reporting, downplays any dramatic shape change this year at all. A fingerprint sensor built into the side button or Action button has also come up repeatedly as a possibility, aimed at making Apple Pay authentication easier during workouts, though that particular feature may not make the cut this generation. Pricing looks stable regardless of how the design question shakes out, with Apple holding the Ultra at $799 across three straight generations already.
Taken together, the sensor overhaul and chip upgrade look like the safest bets heading into September, while the design question stays genuinely up in the air until Apple takes the stage.
