After nearly a week with the Apple Watch SE 3, I’ve found it to be the best Apple Watch for most people if you can live without the latest design and advanced health features. It matches the Series 11 and Ultra 3 in speed and smoothness, offers solid battery life, and feels like a compact yet uncompromised Apple Watch.

Apple Watch SE 3: One-Minute Review

What if I told you Apple has managed to trickle down nearly all the major features you’d expect from an Apple Watch into an entry-level model that doesn’t break the bank and still feels right at home in the lineup?

That’s exactly what I found after testing the brand-new Apple Watch SE 3 for nearly a week.

The SE 3 doesn’t reinvent the wheel – it’s very much a classic Apple Watch. It comes in two sizes, 40mm and 44mm, and two colors. It still has the Digital Crown, uses the same charger, and sits on the wrist just like before. But it finally fixes one of the biggest complaints with the SE line by adding an Always-On display.

No, the display doesn’t slope at the edges like the newer Series models, but that’s not really a drawback here. The SE 3 still looks and feels like a classic Apple Watch, with an aluminum build, tougher Ion-X glass, and solid sizing that make it both durable and practical – especially for parents buying one for kids. The bezels are a bit thicker, and brightness tops out at 1,000 nits, which can make it harder to see in direct sunlight, but for everyday use, the screen gets the job done.

Performance is where the SE 3 really shines. With the same S10 chip that powers the Series 11 and Ultra 3, watchOS 26 feels just as smooth here as it does on those higher-end models. Apps open instantly, navigation is quick, and gestures like Double Tap and the new Wrist Flick add a nice layer of convenience. Sure, you don’t get every health feature – there’s no ECG, Blood Oxygen, or Sleep Apnea tracking – but the essentials are here: heart rate tracking with alerts, the new Sleep Score with retroactive trends, activity tracking, and temperature sensing for cycle tracking.

Compared to the SE 2, this is a big step forward. It’s faster across the board, handles daily tasks with ease, and finally supports fast charging. Battery life is still rated at 18 hours, but with Low Power Mode you can stretch it closer to 32 if needed. In my testing, it comfortably lasted a full day, even with sleep tracking. The new 5G antenna adds efficiency if you opt for the LTE model, though speeds feel about the same as before.

At $249 / £219 / AU$399 for the 40mm version, there’s never been a better Apple Watch from a pure value perspective. And if you don’t need the ultra-modern slimmed-down looks of the Series 11, the rugged features of the Ultra 3, and can live without ECG, Blood Oxygen, or Sleep Apnea tracking, then the Apple Watch SE 3 is likely the model for you.

Apple Watch SE 3: Design

• The Apple Watch SE now has an always-on display
• It can run more complex watch faces
• It doesn’t use the Series 10 / 11 body, but an older model

The Apple Watch SE 3 doesn’t stray from Apple’s proven formula and looks much like an Apple Watch Series 9 or older. It features an aluminum shell with a nylon composite back – so yes, you can put the rumor of an all-plastic build to rest once again – and comes in two sizes: 40mm or 44mm.

The bezels around the LTPO OLED display are thicker than those on the Series 10 or 11, which curve down at the edges. But considering the price, that feels like a fair compromise – especially since it’s an Always-On display. Even when it’s not in use, it dims the brightness and slows the refresh rate so you can still see the time and any complications you’ve set.

The display also protected with the latest Ion-X glass, bringing the screen’s durability on par with the Series 11 and making it four times more durable than the SE 2. Considering many parents choose the SE for kids, that extra toughness is a major win.

This removes one of the biggest reasons for skipping the SE in favor of a pricier model: you no longer have to give up the Always-On display. Once you’ve used it, you really can’t go back. In a meeting or a class, you can simply glance down – or check a notification – without raising your wrist.

While it feels smaller compared to the 46mm Series 10 or 49mm Ultra 3, it still provides plenty of room for navigation. You can scroll through Photos, swipe through Maps, check an extended forecast, and even view Notes (a new perk of watchOS 26). The Flow watch face, with its bubble Liquid Glass typeface set against a lava lamp-like background, runs smoothly. The display is harder to view in direct sunlight and fairly reflective, and it tops out at 1,000 nits of brightness.

Like any other Apple Watch, the SE 3 has the Digital Crown – a key interface control – and the main button on the right-hand side. It also features a two-speaker grille, like the Series 11, and you can play music, listen to podcasts, or take calls on speakerphone. It’s not on par with AirPods Pro 3, but it’s surprisingly loud.

The band system hasn’t changed, but is a little complex. The SE 3 40mm will work with bands designed for older Apple Watches up to 41mm in size. The 44mm SE 3 will work with bands for itself, older 45mm Apple Watches, and any Apple Watch Series 10 or 11.

Those larger bands can also be used with other large watches like the Apple Watch Ultra 3 – but it doesn’t work the other way around, as Ultra 3 bands can’t be used for the SE 3. Phew!

Charging is unchanged, too: the SE 3 uses the rear sensor stack with the included USB-C magnetic disc charger.

If you’re upgrading from the SE 2, the case sizes are identical: 44mm by 38mm by 10.7mm, or 40mm by 34mm by 10.7mm. Color options are now just two – Starlight or Midnight – and I do wish Apple offered more variety. Of course, you can add personality through first- or third-party bands.

It might not be the most modern-looking Apple Watch, but the SE 3 still holds its own against other smartwatches. And at the same MSRP as the previous generation, with more features included, it’s likely the best value in the entire lineup.

Apple Watch SE 3: Features

• Gestures come in really handy on the SE 3
• It offers most, but not all, of the health features that the Apple Watch is known for
• The new Sleep Score is a major standout

I’ve been testing the Apple Watch SE 3 alongside the Series 11 and the Ultra 3, and while that might seem like an easy way to spot differences, all three are powered by the same Apple-made S10 chip. Specifically, it’s a 64-bit dual-core processor with a GPU and a 4-core Neural Engine, and it ensures watchOS 26 runs smoothly.

This means the most affordable SE 3 is nearly as capable as the most expensive Ultra 3 or the mid-range Series 11. After a quick setup, I was greeted with Apple’s iconic “hello” in Liquid Glass and could take a tour of watchOS 26. That’s especially helpful since the SE 3 may be someone’s first Apple Watch.

Navigation is simple: your home screen is your chosen watch face, which you can long-press to edit or swap. Click the main button on the right to pull up Control Center for quick settings, or press the Digital Crown to view all your apps. Everything runs quickly here.

Two gesture controls stand out. Double Tap lets you pinch your forefinger and thumb to perform actions like answering a call, opening an app, or controlling music. Wrist Flick, new with watchOS 26, lets you flick your wrist back to return to the interface. After using it daily, I’ve wondered why it wasn’t available before.

The S10 chip also enables several health features, although compared to the Series 11 or Ultra 3, you’re missing Hypertension Notifications, Blood Oxygen tracking, ECG, and Sleep Apnea Notifications on the SE 3.

The SE 3 does offer Sleep Tracking with the new Sleep Score, which gives you a rating – Very Low, Low, OK, High, or Excellent – and a score from 0 to 100. If you’ve tracked sleep before, it retroactively assigns scores to show trends. It uses the same second-generation heart rate sensor stack as the SE 2, providing monitoring with alerts for low, high, and irregular rhythms. You also get full activity tracking and temperature sensing from a wrist sensor, which upgrades cycle tracking with retrospective ovulation estimates.

Overall, the SE 3 delivers the core health and activity tracking you’d expect from a smartwatch. In side-by-side use with the Series 11 and Ultra 3, it produced similar results for workouts, sleep, and heart rate.

Beyond the new media playback function, it also gets the voice isolation feature for calls that debuted with the Series 10. This means you can comfortably take calls in noisy environments, like at a ballpark or a botanical garden, without worrying the person on the other end won’t hear you. It does an excellent job of focusing on your voice and blocking background noise.

Apple Watch SE 3: Performance

• It offers the same performance as the Series 11 or Ultra 3
• watchOS 26 runs very well here with fluid and responsive interactions
• You get basic fast charging

The Apple Watch SE 3 performs in line with the Series 11 and Ultra 3. Swapping and customizing watch faces happens smoothly, applications open quickly, and navigation around watchOS 26 feels fluid with the Liquid Glass updates.

It’s also noticeably faster than the SE 2. Apple says it’s up to 30% faster with the GPU and has 60% more transistors in the CPU. It’s a lot of jargon, but in practice, it runs laps around the SE 2 in day-to-day use—opening apps, scrolling through photos, starting workouts, and running third-party apps.

This responsiveness makes sense considering the SE 2 was released three years ago and powered by the S8 chip. The S10 ensures watchOS 26 runs well across the board, from activity and workout tracking to health monitoring.

It also helps extend battery life, which on my SE 2 has been showing its age. Apple rates the SE 3 for up to 18 hours, the same as the SE 2, but with a newer lithium-ion battery and Low Power Mode support. If enabled, you’ll lose some functionality, including the Always-On display, but it can stretch runtime to 32 hours.

In TechRadar’s testing with the SE 2, it often exceeded the 18-hour window. With the SE 3, depending on use, it can similarly last a full day with moderate use, including sleep tracking. As with the Series 10, you’ll likely need to recharge once in the morning or evening.

The new 5G antenna on the LTE-enabled model may improve efficiency. It adds 5G alongside 4G LTE, and in my tests, it performed well for messages, calls, and emails when not connected to my iPhone, though speeds were about the same as previous Apple Watches.

Finally, fast charging has arrived on the Apple Watch SE, and it’s a welcome addition. According to Apple, with the included charger and a 20-watt power brick, you can go from 0% to 80% in about 45 minutes. In practice, it was closer to an hour when charging from completely dead, but it hit 30% in about 15 minutes, which is enough for a quick top-up before bed or in the morning.

All in all, the Apple Watch SE 3’s performance doesn’t leave you wanting more. Its speed and responsiveness are in line with the Series 11 and Ultra 3, just in a smaller build with thicker bezels.
