Apple Watch SE 3 Review (2026): Enough Watch for Most?

This Apple Watch SE 3 review looks at the mid-range model in Apple's smartwatch line and asks whether it covers what most people want from a wrist device. It brings an Always-On Retina display to the SE line for the first time, runs on the S10 chip, and adds sleep and safety features. It is aimed at first-time Apple Watch buyers and at families setting up a watch for a child. This review is based on manufacturer specs and on what independent expert reviews report, not on our own hands-on testing.

Apple Watch SE 3 review: design and build

The SE 3 comes in 40mm and 44mm aluminum cases, so there is a choice for smaller and larger wrists. Weight is listed at 26.3 grams for the 40mm GPS model and 32.9 grams for the 44mm.

The display is an Always-On Retina LTPO OLED panel at 326 pixels per inch, with a peak brightness of 1000 nits. The 40mm model has a resolution of 324 by 394 pixels, and the 44mm has 368 by 448 pixels. An Always-On screen means the watch face stays visible when your wrist is down, so you can check the time without raising your arm. Reviewers single this out as a big upgrade for the SE line.

The cover is Ion-X glass, which Apple says is 4x more crack resistant than SE 2. Water resistance is 50 meters (ISO 22810:2010), which covers swimming.

The design is where the criticism starts. A common complaint is that the look is dated, with thick bezels around the screen. Colors are limited to Midnight and Starlight, which reviewers also mention as a drawback.

Performance and the S10 chip

The SE 3 uses the S10 chip, a 64-bit dual-core processor with a 4-core Neural Engine. Reviewers say this keeps the watch fast and smooth, in the manner of pricier Apple Watches.

The S10 also brings gesture controls. Double Tap and wrist flick gestures are included. Storage is 64GB.

Health and fitness features

The health suite is where the SE 3 earns its place. It offers a sleep score, sleep apnea notifications and wrist temperature sensing. Reviewers praise these features.

There are limits. The SE 3 has no ECG or blood oxygen sensors, and reviewers list this among the main criticisms. If you have a specific reason to want either measurement, this is the point to stop and look at a higher-tier model. For general activity, workouts and sleep, the feature set covers the essentials.

Safety features

Safety is a strong part of the package. Crash Detection, Fall Detection and Emergency SOS are all included, and reviewers praise them. These are the features you hope never to use, but they are a good reason to put a watch on an older relative or on someone who runs or cycles alone.

The SE 3 can also be had with optional cellular. The options are 5G (RedCap) and LTE. Cellular lets the watch work without your phone nearby. It also supports Apple Watch For Your Kids, so it can work as a child's first watch. If that is your plan, see our guide to the best smartwatches for kids to compare it with watches made specifically for children.

Battery life and charging

Battery is the other area reviewers flag. Apple rates it at up to 18 hours of normal use, and up to 32 hours in Low Power Mode. Reviewers describe this as only about one day, so plan on charging daily.

Charging is quick, which softens the blow. The watch reaches up to 80% in about 45 minutes, and 15 minutes gives up to 8 hours of normal use. That said, if you want to wear a watch to bed for sleep tracking and also use it all day, you will need to find a charging window somewhere in the routine.

If you prefer a watch you can leave on a week at a time, the SE 3 is not the right type of device.

Connectivity

The connectivity list is modest but covers the basics: Bluetooth 5.3, Wi-Fi 4 (802.11n) 2.4GHz and L1 GPS. GPS handles route tracking for runs, walks and rides. The cellular options noted above are optional extras rather than standard.

What experts like and what they criticise

The SE 3 averages 8.6/10 across 5 expert reviews. Macworld and Pickr each score it 4.5/5, Tom's Guide and Tech Advisor score it 4/5, and Engadget gives it 90/100. It is also recommended in 6 independent expert guides.

Reviewers consistently praise:

• the Always-On Retina display, which is a big step up for the SE line;
• the S10 chip, which keeps performance smooth;
• the sleep score, sleep apnea notifications and wrist temperature sensing;
• Crash Detection, Fall Detection and Emergency SOS;
• the tougher Ion-X glass and 50m water resistance.

The common criticisms are a dated design with thick bezels, battery life rated at about a day, the absence of ECG and blood oxygen sensors, and a choice of only two case colors.

Who should buy the Apple Watch SE 3

This watch suits people who want the main Apple Watch experience without paying for the top of the range. That includes:

• First-time Apple Watch buyers, who get a fast chip, a screen that stays on and core health tracking.
• Families, because of the optional cellular models and Apple Watch For Your Kids support.
• Swimmers and active people, thanks to the 50m water resistance and tougher glass.
• Anyone who wants sleep insights, including sleep score and sleep apnea notifications.

Who should skip it

Look elsewhere if you want ECG or blood oxygen readings, since the SE 3 does not have those sensors. Skip it too if multi-day battery life is a priority, or if you care about a modern, thin-bezel look. People who want a wider range of case colors will also find the choice limited.

How it fits in the smartwatch market

In the mid-range part of the market, the SE 3 is a balanced option. It sits at a mid-range price and lacks ECG and blood oxygen sensors, while offering the S10 chip and safety features. Our guide to the best fitness trackers is a good next stop if you are unsure whether you need a full smartwatch.

Verdict: is the Apple Watch SE 3 worth buying?

For most people who want an Apple Watch, the SE 3 is a sensible choice. Expert scores are strong, and reviewers praise the Always-On display, the S10 chip, and the sleep and safety features. The compromises are clear and well documented: daily charging, an older look and no ECG or blood oxygen. If those do not bother you, it is an easy watch to recommend.
