You could say I’ve had a busy past few days – between rocking the AirPods Pro 3 and fully reviewing the Apple Watch Series 11 and Apple Watch SE 3, I’ve also been daily-driving the Apple Watch Ultra 3.
It’s finally a proper upgrade for the most rugged, go-anywhere, climb-every-mountain Apple Watch. In 2024, it got a slight spec bump and a fresh paint job, but for 2025 Apple’s really rounding out the Ultra 3 in a way that makes it a compelling upgrade for folks with the first or second generation Ultra, especially the former.
I’m still in the midst of testing, so consider this my review-in-progress, and my early impressions of the Apple Watch Ultra 3, beyond the environs of Apple Park and the launch event. TechRadar’s Senior Fitness & Wearables Editor Matt Evans – himself a smartwatch aficionado – will also be weighing in soon, putting the Ultra 3 (and himself) through a battery of fitness, health, and exercise tests.
Apple Watch Ultra 3: Price and availability
- $799 in US
- £749 in UK
- AU$1,399
The Apple Watch Ultra 3 is available for $799 / £749 / AU$1,399. This is the same price as its predecessor in most regions, although the Ultra 3 is slightly cheaper in the UK – the Apple Watch Ultra 2 cost £799 in the UK, so the Ultra 3 is better value there.
Apple Watch Ultra 3: Design
- Same 49mm case as Ultra 2
- Slightly larger screen
- Recycled Natural or Black Titanium finishes
In the same way that Apple is sticking with the rounded ‘squircle’ look of previous iterations for its Series 11 smartwatch, it’s clear that the Apple Watch Ultra 3 is sticking with its tried-and-tested design here. It still offers a supersized 49-millimeter display in a thicker, more durable titanium body.
The Ultra 3 comes in Natural Titanium or Black Titanium, and I’ve been testing the latter, which looks especially sleek. You can pair it with a custom-match Ultra Milanese Loop – a personal favorite band of mine – with one of the new 2025 options, like the Trail Loop, which now features reflective material on the edges, or with older bands that fit the 49mm / 46mm / 44mm sizes.
One change Apple made here is using a 3D printing process to build the case from recycled titanium, though you won’t notice any difference in appearance. The display, however, is seriously improved. Like the Series 11 – and the Series 10 before it – the Ultra 3 now boasts an always-on Retina OLED display with an LTPO3 panel, giving it finer control over the refresh rate for additional smoothness in motion. This shines with watch faces like the new Flow, Waypoint, or Exactograph.
It also enables wide-angle viewing, so even when glancing to the side you have a better chance of reading what’s on the display – I’ve found this especially helpful when checking notifications with my arm extended or in low brightness. Apple has also slimmed down the bezels by 24% all around. While noticeable when comparing the Ultra 3 to the Ultra 2 side by side, it’s most apparent when viewing maps – like hiking trails – or photos on the 49mm display.
The Ultra 3’s display can flex its brightness from as high as 3,000 nits in peak sunlight to as low as 1 nit in darkness. Much of the interface uses the Liquid Glass design language introduced in watchOS 26; and even though it looks snappy, it’s also plenty fast for handling actions thanks to the S10 chip inside.
It still charges with the same magnetic puck included in the box, but now supports faster charging.
Apple Watch Ultra 3: Features and performance
- Emergency SOS instructions intuitive
- Satellite connectivity genuinely useful
- I’m loving the new Sleep Score software update
Satellite connectivity for communication makes a lot of sense on a device that you’re likely to be wearing into areas without cell service, and the Apple Watch Ultra 3 is the first Apple Watch to support satellite connectivity.
The headline feature Apple announced at its September launch event was Emergency SOS via Satellite, and while I hope you never need it, I did get a demo at Apple Park. Much like the iPhone’s satellite connectivity, it walks you through the process of sending an alert: identifying the issue, guiding you on how to point your wrist for a satellite connection, packaging the info, sending it into orbit, and beaming a response back down.
In the demo, we triggered SOS on the Ultra 3 by dialing 911. Once it realized there was no grid connection, it began sending an emergency text via satellite. The watch guided us through a questionnaire – we selected “lost or trapped,” confirmed it was just us, and noted no active injuries. This is especially handy if you’re lost on a trail. As a final step, you can also notify emergency contacts.
The watch then instructed us to move our wrist left until it locked onto a satellite. At that point, it packaged the watch’s location, questionnaire details, and the linked medical ID. A relay center receives this data and can send messages back down.
This was, of course, a demo, but it shows how impressively the system works. Notably, it can sometimes transmit data without you moving your wrist, which could be helpful if it’s triggered as a backup during crash or fall detection.
Emergency SOS via Satellite is available for free for two years in the United States – though Apple has a history of extending that – and in the UK and Australia, it’s also free, along with the additional Find My features, which also operate via satellite. I was able to test Find My myself, but in the US, Find My and Messages require an active cellular plan.
With Find My, you can send a basic message (with a character limit) via satellite and even update your Find My location. You’ll go through the same process of moving your Ultra 3 into the right path of a satellite as it passes overhead. With Find My, you’ll know the location was updated this way via a satellite icon on the map next to the person.
Satellite connectivity is a genuinely useful addition to the Ultra 3, and I’m keen to test the Messages and Find My functions more. Beyond this, the Ultra 3 also gets a number of new features as part of watchOS 26, including the Liquid Glass interface, new apps like Notes, and a new Wrist Flick gesture.
Just like the Series 11 and SE 3 – as well as some older models that can run watchOS 26 – the Ultra 3 also gets the new Sleep Score. This builds upon the watch’s ability to track sleep and detail time spent in each stage but now quantifies it with a score from 0 to 100. I’m really enjoying this feature so far, and it feels like it’s about time it arrived here.
The Ultra 3 also adds Hypertension Notifications, meaning that on a rolling 30-day basis, the watch can alert you to potential hypertension (high blood pressure) and recommends you see a doctor for a full diagnosis. This feature is FDA-approved for use in the US.
While the Apple Watch Ultra 3 is technically getting an upgrade to the S10 chip, it’s mostly a repackaged version of the S9 chip found in the Ultra 2. The good news is that the Ultra 3 still feels just as responsive as the other new Apple Watches and competing smartwatches on the market. I think you’d be hard-pressed to slow it down.
This is paired with a new 5G antenna and redesigned antenna band visible around the outer lip of the watch. Apple says it’s more efficient than the previous onboard antenna, and can use two bands at once when needed to improve reception.
Apple also redesigned the internals of the Ultra 3, and thanks to that, there’s a bigger battery inside. Apple rates the Ultra 3 for up to 42 hours with normal use, and I’ve easily been hitting a long day and a half with sleep tracking before noticing a meaningful drop in battery life. It’s simply a powerhouse, and I’ll be testing it more, including the Low Power Mode that can stretch runtime to a remarkable 72 hours.
