Apple just revealed the Apple Watch Ultra 3, and while there's not much changed on the outside, there's a few useful changes internally.

The Apple Watch Ultra has had an odd life cycle as a generational update was skipped in 2024. All Apple did was re-release the Apple Watch Ultra 2 in black.

Now, a true upgrade has arrived in 2025 with the Apple Watch Ultra 3. It gained the new hypertension detection and Sleep Score features revealed for Apple Watch Series 11, plus has a new satellite connectivity feature.

The hypertension feature isn't quite the blood pressure monitoring the rumors called for, but it's a step in that direction. Apple expects to notify 100 million people in the first year of this condition.

The display has been stretched ever so slightly without changing the case size. It also has an incredible 42 hour battery life with up to 72 hours in Low Power Mode.

Smartwatch features montage: fast charging, hypertension alerts, satellite communication, 3D printed case, sleep tracking, workout app, GPS, bright display, 42-hour battery, gestures, 5G, largest display.

Returning Apple Watch Ultra features

The Apple Watch Ultra debuted as a distinctly rugged model with core features that set it apart from the Apple Watch Series. The 49mm case includes a large display that was only slightly surpassed by Apple Watch Series 10 in spite of its smaller 46mm case.

Apple Watch Ultra has a raised rim around the edge of the display, an extra-large Digital Crown that's easy to operate with gloves, an enclosure that works when diving up to 100 meters, and meets the MIL-STD 810H. It has always been showcased in extreme conditions where athletes navigate deserts, climb mountains, or dive in the arctic.

Apple Watch Ultra 2 introduced a new black color

The Action button debuted on the original Apple Watch Ultra and is painted orange. It can be programmed with specific actions that can launch apps or activate an emergency siren.

Apple Watch Ultra represents the premium end of Apple's wearable. The Series models have a much smaller case and can only fit so much, while Ultra models can pack more features and experiment with new concepts.

Apple Watch Ultra 3 is available to pre order Tuesday after the event. It is $799 and comes in natural titanium and black titanium.
