New Apple Watch superguide: Details of the 2025 Apple Watch Series 11, Ultra 3 and new Apple Watch SE

New Apple Watch 2025: Summary

Release date: Apple Watch Series 11, Ultra 3, and SE (3rd-gen) were revealed at Apple’s ‘Awe Dropping’ event on September 9, 2025. They went on sale on September 19.
Price: Apple Watch Series 11 starts at $399, Ultra 3 from $799, and SE (3rd-gen) from $249.
Design: Aside from larger displays on the Apple Watch SE 3 and Ultra 3, there’s little change.
Specification changes: 5G is here for Series 11 and Ultra 3, while the latter gets satellite connectivity. No processor bump, though.

On September 9, Apple held its September event, dubbed “Awe Dropping“, and while the iPhone 17 was the focus, we got a trio of Apple Watch models, too. From the Apple Watch Series 11, which adds 5G, to the much more capable Apple Watch SE and rugged Apple Watch Ultra 3, there’s a lot to cover.

Perhaps the biggest news is that Apple did, in fact, manage to get blood pressure monitoring and hypertension detection onto its wearables this year. Apple says the condition is dubbed a ‘silent killer’, and has been fine-tuning its machine learning algorithm to help notify over 1 million users of potential hypertension. While it’s great that it’s finally on the Apple Watch it’s not unique to the 2025 models though: the hypertension detection feature will also be available on Series 10, Series 9 and Ultra 2 with the arrival of watchOS 26.

Alongside that, sleep tracking is vastly improved. A new Sleep Score will help calculate an easy-to-understand number based on sleep duration, consistency of bedtime, and sleep stages, all wrapped up by an algorithm developed using 5 million nights of sleep data. Again, the Sleep Score feature isn’t unique to the new watches: that will work on Series 6, Ultra 1 watches, and newer Apple Watches. You don’t need to buy a new watch to benefit from these new features.

So, that’s the top-level stuff, but what about each device? Let’s get into it.

New Apple Watch 2025 design & dimensions

The big design changes came to the Apple Watch Series 10 in 2024 with bigger screens. This time round the changes are more subtle. The Ultra gets a fractionally larger screen which allows for a few more pixels. The SE will finally show the time all the time thanks to the Always On display. What else is new? We explain the design changes below.

Apple Watch Series 11 design and dimensions

More scratch-resistant, but mostly the same as the Apple Watch Series 10 on the outside.
Available in Jet Black, Silver, Rose Gold, Space Gray in the standard aluminum body, or Natural, Gold, and Slate Titanium versions.

Apple

Apple updates its mid-range Apple Watch every year, but it doesn’t always deliver major changes. 2024’s Series 10 brought a larger display and thinner design, and at a quick glance, the Apple Watch Series 11 is much the same.

It comes in Jet Black, Silver, Rose Gold, and the new Space Gray colorways for the standard versions, with Titanium options in Natural, Gold, and Slate.

The new display is more scratch-resistant than 2024’s model. The Ion-X glass that comes with the aluminium case is 2x more scratch-resistant than the Series 10, and the titanium version offers the same tough sapphire crystal display used for the Ultra 3.

Apple Watch Ultra 3 design and dimensions

Larger display due to thinner bezels, but not massively different to the Apple Watch Ultra 2.
Comes in the same natural and black titanium options.

Apple

The Apple Watch Ultra 3 is, as was rumored, getting a slightly larger display, in fact Apple proudly states that it’s got the largest Apple Watch display ever. On paper though that larger display is only fractionally bigger: Apple still describes it as 49mm, but the difference is in pixels and visible area: 422×514 pixels rather than 410×502 pixels and 1,245 sq mm display area instead of 1,185 sq mm display area.

The ‘larger’ display is possible because Apple was able to reduce the bezel size (apparently the borders are 24% thinner), and that’s thanks to the new new, LTPO3 wide-angle OLED panel.

That display is also described by Apple as a tough sapphire crystal display, which should make it more durable than the Ultra 2. The Series 11 offers this same durable sapphire crystal display with the titanium case.

The Apple Watch Ultra 3 comes in Black and Natural titanium hues, which is… about what we’d expect.

Apple Watch SE 3 design and dimensions

Finally has an always-on display.
Available in Starlight and Moonlight.

Apple

The SE is now in its third generation, and it’s finally gaining an always-on display.

Not much has changed visually. It’s the same 44mm or 40mm case, and the colours are the same, with the omission of the silver aluminium option in favor of Starlight and Moonlight. As a result, existing silver aluminium straps may not match as well as they might have.

Like the other 2025 watches, the SE 3 display is more scratch-resistant than its predecessor. The Ion-X glass that comes with the aluminium case is 4x more scratch-resistant than the Apple Watch SE 2 (and just as scratch-proof as the Series 11).

New Apple Watch 2025 features

Apple

Blood pressure monitoring: Apple has introduced the much-hyped hypertension detection feature. It will be available for the Apple Watch Series 11 and Ultra 3 – and also the Apple Watch Series 9 and 10 and the Ultra 2.
AI features: Live translation, adaptive notifications, and contextual suggestions via Apple Intelligence on iPhone.

Apple’s hypertension detection algorithm could help identify hypertension for more than a million users, according to the company. It”s not unique to the new Apple Watch Ultra or Series 11 though, it’s coming to the 2024 and 2023 Apple Watches too. So you’ll also find it on the Series 10 and 9, and the Ultra 2.

Like the hypertension alerts, most of the new health and fitness related features are part of watchOS 26. For example:

Live Listen transcription and Live Translation will automatically transcribe phone calls and messages on your Apple Watch screen in real time.
Workout Buddy will use Apple Intelligence from your iPhone to provide you with words of encouragement based on your workout data and fitness history.
Automatic volume adjustment, so that notifications are adjusted depending on your environment.
Sleep Score will also be a feature of this year’s models and all models running watchOS 26. That includes Series 6 and Ultra 1 watches.
New Smart Stack hints that will make proactive, context-aware suggestions when your watch detects a specific situation like an appointment or new location.

New Apple Watch SE 3 features

The Apple Watch SE 3 gains some new heath features that weren’t available on the SE 2, including a wrist temperature sensor and Sleep Apnoea notifications.

Other new features making their way to the Watch SE 3 include on-device Siri, the wrist flick and double tap gestures. Plus the SE 3 will be capable of media playback, unlike the previous generation.

New Apple Watch 2025 specs

Processor: All models feature the S10 chip.
Connectivity: 5G has come to Apple Watch Series 11 and Ultra 3, while the latter gains satellite connectivity, too.

5G and satellite

The Apple Watch has had an option for LTE cellular connectivity since the Series 3, and now the Apple Watch Series 11 and Apple Watch Ultra 3 will finally move to 5G speeds.

Not only that, but Apple Watch Ultra 3 will add satellite connectivity for emergency contacts, messaging, and location sharing when you don’t have any connectivity at all. Apple says it doubled the strength of the internal radio to achieve that feat.

S10 processor

The Apple Watch Series 11, Apple Watch Ultra 3, and Apple Watch SE 3 were expected to see a spec bump to a new chipset, but that’s not the case. In fact, the Apple Watch Series 11 and Ultra 3 will have the S10 chip – the same as the Apple Watch Series 10 last year.

If you’ve been waiting for a new Apple Watch SE model, though, your patience is being rewarded. It’s jumping to S10, too.

Battery life

Apple has improved the battery life of the Series 11 and Ultra 3 models. The Series 11 will now get up to 24 hours of battery, with the Ultra 3 reaching 42 hours.

The SE still hits 18 hours, but it’s a little behind the curve. It’s gaining a wrist temperature sensor for now, though.

Other specs

The Apple Watch SE 3 will get a speaker that is capable of playing audio.

New Apple Watch 2025 release date

Announcement date: 9 September, 2025.

The new 2025 Apple Watch models are shipping now.

New Apple Watch 2025 price

Apple Watch Series 11: From $399/£369.
Apple Watch Ultra 3: From $799/£749.
Apple Watch SE 3: From $249/£219.

Apple hasn’t changed its pricing structure since the Apple Watch Series 3, and it’s still holding firm today. That means the Series 11 will start at $399 for the 42mm model, and $429 for the larger 46mm version, with an extra $100 for cellular, while the Apple Watch Ultra 3 will likely cost $799/£799 (which includes cellular connectivity).

New this year is the Titanium Series 11, which will start at $699 and comes with cellular included.

The Apple Watch SE currently starts at $249/£219, but can often be found for as low as $189 at Amazon U.S. With the rumors of a new plastic design, it’s possible the Apple Watch SE gets another price cut, as it did when the 2nd-gen model arrived in 2022.
