Here’s how they break down:

Series 11 vs. Ultra 3, SE 3 bodily designs

The core rounded-rectangle design of the Apple Watch has seen incremental adjustments since its first iterations. The Series 11 shares the slimmer 9.7mm top profile of the Series 10, with 42mm and 46mm diagonal sizes. Weight is mild throughout the board, from 29.7 to 43.1 grams relying on measurement and case materials. Aluminum fashions are available in area grey, jet black, rose gold or silver, whereas titanium variations are supplied in pure, slate or gold finishes.

The Apple Watch SE 3 is barely thicker (10.7mm) and barely smaller, with 40mm and 44mm sizes. Its design most intently harkens again to earlier Apple Watch fashions. It weighs 26.4 grams or 33 grams, relying on the case measurement. As the no-frills choice, the SE 3 is accessible in both midnight (black) or starlight (silver).

The Ultra 3 is essentially the most important departure from the unique design, with a thickness of 14.4mm, a 49mm diagonal, and a weight of 61.6 grams. Its titanium physique is available in both pure or black — except you go for the Hermès version, which is barely supplied in pure. 

CNET lead author Vanessa Hand Orellana described the Ultra 3 in her overview as being “like the luxury Land Rover you see in safari brochures: It’s adventure-ready on the outside, with all the modern conveniences on the inside.” The physique can also be 3D-printed from 100% recycled titanium, however you’d by no means realize it; there are not any telltale layering marks discovered on most 3D-printed objects.

Each watch has Apple’s Digital Crown and a aspect button. The Ultra 3 additionally features a programmable Action button, which may, for instance, begin a exercise with a single press.

Aside from appears, all three Apple Watch fashions are constructed for sturdiness. The SE 3 is waterproof to 50 meters, so that you needn’t child it — whether or not you are showering, swimming or simply dwelling via a wet Pacific Northwest day.

The Series 11 can also be rated for water resistance to 50 meters, whereas the Ultra 3 doubles that to 100 meters. They’re additionally each licensed IP6X dust-resistant, which is healthier than the SE.

Series 11 vs. Ultra 3, SE 3 shows

The Series 11 and Ultra 3 each use an LPTO 3 OLED show, which presents an always-on show and a large viewing angle, so you do not want to take a look at it head-on to see the time. It may also get very brilliant: 2,000 nits of peak brightness for the Series 11 and three,000 nits (the identical because the iPhone 17 Pro) for the Ultra 3. 

The energy-efficient display can refresh its show at only one nit of brightness as soon as each second when in its passive state, so you possibly can at all times see the second hand or indicator (relying on the watch face).

The show is protected by a sapphire crystal on the titanium Series 11 and the Ultra 3. According to Apple, the aluminum Series 11 makes use of Ion-X glass, which is twice as scratch-resistant because the Series 10.

In previous generations, the SE was caught with the lowest-quality display, however not this time. The SE 3 will get an always-on LTPO OLED show that reaches as much as 2,000 nits of brightness and dims to only 2 nits when inactive. But it does not refresh as typically because the Series 11 and Ultra 3, so the seconds indicator solely seems when the display is energetic. It’s nonetheless an enormous “quality of life” bump from prior SE watches, which do not have an always-on show mode.

Series 11 vs. Ultra 3, SE 3 battery life

One surprise with the new Apple Watch lineup is improved battery life in the Series 11 and Ultra 3, plus a fast-charge option on the SE 3 that lets you top up for a night’s sleep after a full day.

Apple claims up to 24 hours of use on a single charge for the Series 11, up from 18 hours for the Series 10. It also claims up to 38 hours in Low Power mode, a notch above the Series 10’s 36 hours. That fast-charging option can bring the battery level up to 80% in 30 minutes, but charging the watch for just 15 minutes can boost it for up to 8 hours. 

Hand Orellana writes in her Series 11 review, “The six-hour battery bump on the Series 11 might not sound like a lot on paper, however it’s given me some welcome respiration room to determine a greater charging technique.”

The SE 3 still delivers up to 18 hours of use, or 32 hours in Low Power mode. It also supports fast charging — up to 80% in 45 minutes, or about eight hours of use from a quick 15-minute top-up.

If you want the most time between charges, the Ultra 3 is the Apple Watch to get. It can last for up to 42 hours, per Apple, or up to 72 hours in Low Power mode. Fast charging its larger battery takes it to 80% in about 45 minutes, and 15 minutes on the cable will give you roughly 12 hours of power.

Some of these gains come from Apple factoring in a night’s sleep, but credit also goes to the more power-efficient LTPO 3 screen in the Series 11 and Ultra 3.

It’s one thing to reference Apple’s claims, but what about battery life in practice? In Hand Orellana’s review of each model, she recorded even better battery life than Apple’s estimates. Keep in mind your daily usage will affect results, but here’s what she found:

Series 11 vs. Ultra 3, SE 3 health features

The Apple Watch SE line has always sacrificed some hardware and features to remain the least expensive option, and the SE 3 continues that tradition — but not to the same extent. It lacks an electrical heart sensor found in the Series 11 and Ultra 3, so it can’t take heart readings using the ECG app to look for signs of atrial fibrillation (Afib).

According to Apple, the SE 3 uses a second-generation optical heart sensor that tracks heart rate during exercise, sleep and potential emergencies — though, like all Apple Watches, it can’t detect heart attacks or measure blood oxygen. The Series 11 and Ultra 3 upgrade to third-generation optical heart sensors.

The SE 3 is also missing a water temperature sensor and depth gauge, making the Series 11 and Ultra 3 better options if you spend a lot of time in water and want to track swim workouts or shallow dives more reliably.

This year’s standout health feature is the ability to analyze data and detect signs of hypertension, or high blood pressure. “It’s not the complete on-the-spot blood strain monitoring Apple followers have lengthy hoped for,” wrote Hand Orellana, “however it’s a serious step ahead — one which Apple says may assist 1 million individuals get identified with hypertension within the first 12 months alone.” 

Like the sleep-apnea tracking introduced last year, hypertension notifications are not a screening tool; think of it as a warning system that prompts you to get checked out by your doctor. The Series 11 and Ultra 3 include this ability (sorry, SE 3), and require 30 days of data collection before triggering notifications. The Series 9, Series 10 and Ultra 2 also get hypertension notifications in WatchOS 26.

Series 11 vs. Ultra 3, SE 3 connectivity

Each Apple Watch model supports cellular connectivity, so you can stay connected even when your iPhone is at home. You can order the aluminum Series 11 models and the SE 3 with the cellular option; the titanium Series 11 and the Ultra 3 include it by default.

What’s unique about these watches is their support for both 5G and LTE networks, offering faster speeds and broader compatibility. Plus, they use 5G Reduced Capacity technology, which is more power efficient than the 5G networking in your iPhone.

They also support Wi-Fi 4 (802.11n) at 2.4 GHz and 5 GHz, Bluetooth 5.3, and L1 GPS location chips. The Ultra 3 includes dual GPS radios (L1 and L5) for more precise location tracking, especially in challenging environments like dense downtown corridors.

Plus, the Ultra 3 offers satellite connectivity directly from the watch. With a direct view of the sky, it can communicate with overhead satellites to send and receive texts, share your location, and access emergency services.

Series 11 vs. Ultra 3, SE 3 processors

One of the biggest surprises in the lineup? The Apple Watch Series 11, Ultra 3 and SE 3 all include the same S10 chip. It’s worth noting that the S10, introduced in last year’s Series 10, isn’t a new processor generation for 2025. But each watch now includes 64 gigabytes of storage, a four-core Neural Engine and a 64-bit dual-core processor.

The only significant difference is that the Apple Watch SE 3 is the only model not to feature Apple’s second-generation Ultra Wideband chip, which enables precise location tracking. You can still use Find My on an iPhone (with UWB) to see if the SE 3 is with you or if you left it at home. But with the Series 11 and Ultra 3, Find My will point you in the right direction as you get closer to your mislaid watch.

WatchOS 26 on the Series 11, Ultra 3 and SE 3

Each model is preloaded with WatchOS 26, which has the new Liquid Glass interface (though in most cases, it’s quite subtle). And all models add features like the new Wrist Flick gesture, nightly sleep scores, Workout Buddy, the Notes app and live translation in Messages. The Series 11 and Ultra 3, with their upgraded sensors, also gain hypertension notifications.
