Apple Watch SE 3 GPS 40mm Review: the no-nonsense Apple watch for everyday use

I’ve been using the Apple Watch SE 3 GPS 40mm in Midnight for a bit now, and it’s basically the “normal person” Apple Watch. Not the flashy ultra-sport one, not the super expensive flagship, just the one you actually wear every day without overthinking it. I picked the 40 mm version with the sport band because I mainly wanted something for notifications, workouts, and to stop me constantly grabbing my phone.

Right away, the thing that stood out is how familiar it feels if you’re already in the Apple world. Setup takes a few minutes with an iPhone, the menus look like what you already know, and you don’t need to watch 20 YouTube tutorials to get going. It’s very much: strap it on, pair it, and it does its job. No drama.

My use is pretty basic but consistent: daily step and workout tracking, checking messages, quick calls, Apple Pay, and sleep tracking. I don’t baby it; I wear it in the shower, at the gym, while cooking, and I sleep with it most nights. So this isn’t a “I used it for one day and wrote a review” situation. It’s more like: here’s how it holds up in a boring, normal life.

If you’re wondering whether it’s worth going for this SE 3 instead of a more expensive Series model, I’ll be honest: for most people who just want a good smartwatch that works well with an iPhone, this one is already more than enough. It’s not perfect, there are a couple of annoying points (mainly battery and size options), but overall it gets the job done without feeling like you overpaid for stuff you never use.

On value, the Apple Watch SE 3 sits in that middle spot: not cheap, but cheaper than the flagship. If you’re already using an iPhone and want a smartwatch that integrates smoothly, it makes more sense than buying a random brand that will always feel a bit clunky next to Apple’s ecosystem. For the price, you get strong performance, a good screen, solid health features, and tight integration with iOS and Apple Pay.

Compared to higher-end Apple Watches (like the Series 11), what you mainly give up are some advanced sensors (ECG, blood oxygen), a slightly nicer screen with thinner bezels, and sometimes better materials. If you’re not obsessing over those, the SE 3 feels like the smarter buy. You basically pay for what you will actually use: fitness tracking, notifications, calls, and payments. The safety features like fall and crash detection are a nice bonus, especially for older relatives or people who drive a lot.

Against competitors like Fitbit or Garmin in the same price range, it depends on what you care about. If you want long battery life and hardcore sports stats, some Garmin models give you more on that front. If you want smooth daily use, app support, and iPhone integration, this SE 3 wins easily. So it’s not the best at everything, but it’s well balanced for normal users.

In the end, I’d say the value is good, not mind-blowing. You’re still paying the Apple tax, but at least here you get a product that’s mature, stable, and easy to live with. If you’re fine charging daily and you don’t need pro athlete features, your money feels reasonably well spent.

Design-wise, nothing shocking: it’s a classic Apple Watch shape, square with rounded corners and noticeable bezels. If you’ve seen any recent Apple Watch in person, you basically know what this looks like. The Midnight colour is a dark navy/black mix; in most lighting it just looks black, which I actually like because it goes with everything and doesn’t scream for attention.

The 40 mm size is on the smaller side, especially if you’re used to big watches. On my 17.5–18 cm wrist, it looks more like a traditional watch than a mini smartphone stuck to my arm. If you like a more discreet look, this size works well. If you want a big screen and bold look, go 44 mm instead. The only slight issue with 40 mm is that some icons and buttons are a bit tight if you have thicker fingers. You get used to it, but it’s there.

The bezels are thicker than on the more expensive Series 11, so you don’t get that fully edge-to-edge effect. In day-to-day use it’s not dramatic, but if you put them side by side you see clearly where Apple saved money. For reading notifications, workout stats, and the time, it’s still perfectly fine. Text is readable, and animations are smooth thanks to the newer processor inside.

Overall, the design is pretty simple: clean, light, and familiar. It doesn’t feel cheap, but it also doesn’t feel overly premium like stainless steel or titanium versions. It’s the kind of watch you’re not scared to bump into a door frame or wear at the gym. If you care more about something that looks like jewellery, you’ll probably end up swapping the strap and maybe wishing you had gone for a larger or fancier case.

Battery life is where you need to be honest with yourself. Apple says around 18 hours, and that’s roughly what I get with normal use. For me, that means: always-on display on, notifications active, a short workout with GPS, and wearing it at night for sleep tracking. With that pattern, I usually hit the charger once a day, often in the morning while I’m getting ready or in the evening before bed.

If you turn on some battery saving options and don’t hammer it with workouts, you can stretch it to a day and a half, maybe a bit more. But realistically, you’ll build a habit of charging it daily. Coming from some Garmin and Fitbit devices that last almost a week, this feels a bit annoying at first. After a while, it becomes part of the routine, like charging your phone. But if you hate the idea of yet another thing to plug in every day, this might bother you.

The positive point: charging is fast. Apple claims up to 8 hours of battery from 15 minutes, and in practice a quick top-up before going out in the evening is usually enough. I’ve had situations where I noticed it at 20% before a night out, dropped it on the charger while showering and changing, and came back to something like 60–70%, which easily covers the rest of the day plus sleep tracking.

Overall, the battery is “fine but nothing more”. It gets the job done for a full day with all features active, but it’s nowhere near the multi-day performance of some sport watches. If you do ultra races or long hikes over several days without access to power, this watch is not made for that. For standard city use with daily charging, it’s acceptable, just don’t expect miracles.

On comfort, this Apple Watch SE 3 is honestly one of the easiest devices I’ve worn all day. The weight is low, the 40 mm size doesn’t overhang the wrist, and the included sport band is very soft. I wear it pretty much all day and most nights for sleep tracking, and there were only a couple of times at the start where I really noticed it when trying to fall asleep. After a few nights, it just blended in.

The M/L band size is meant for 150–200 mm wrists. On my roughly 18 cm wrist, I’m somewhere in the middle holes, and it feels secure without needing to over-tighten. The material doesn’t irritate my skin, even when I’m sweaty at the gym or wearing it in the shower. I’ve had cheaper rubber straps from other brands that caused itchiness or redness after a full day; here, nothing like that so far.

One thing to keep in mind: to get accurate heart rate and sleep data, you need the watch fairly snug. If you wear it too loose, it can slide around and the sensor readings can be off, especially during workouts. Once you find the right hole on the strap, though, it stays put. The watch doesn’t feel bulky under long sleeves either, it slides under a hoodie or shirt cuff without catching too much.

The only minor comfort downside is during warmer days: the standard sport band can get a bit sweaty underneath. It’s not terrible, but if you’re very sensitive to that or you live somewhere hot, you might want to pick up a nylon or fabric strap for daily wear and keep the sport band for workouts and water use. Overall though, for something you wear 16–24 hours a day, comfort is one of its stronger points.

I’m not particularly gentle with my tech, and this SE 3 has been treated like any other everyday watch: gym, showers, cooking, cleaning, and the occasional knock on a door frame. So far, the aluminium case and glass have held up pretty well. No deep scratches, just a couple of very light marks you only see if you tilt it under strong light. The Midnight colour helps hide minor scuffs too.

The watch is water resistant, and I’ve worn it in the shower and while washing dishes without any problem. I’m not a swimmer, so I can’t comment on pool workouts in detail, but for basic water exposure, it’s been totally fine. The sport band also dries quickly and doesn’t keep a weird smell, which is something I’ve had with some cheap silicone bands in the past.

One thing to remember: this is still glass and aluminium, not some indestructible tank. If you’re the kind of person who works on construction sites or regularly bangs your wrists into metal equipment, I’d probably add a screen protector or a light bumper case. It’s not fragile, but it’s also not built to be thrown around.

After regular use, the buttons and digital crown still feel solid, no wobble or weird play. The haptic feedback is still sharp, and the band pin system hasn’t loosened. So in terms of build, I’d say it’s pretty solid for everyday life. Just don’t treat it like a hardcore outdoor watch and expect it to shrug off everything.

In terms of performance, the SE 3 feels fast and smooth. Menus scroll without lag, apps open quickly, and swiping between widgets and notifications is fluid. Compared to older Apple Watches or cheaper Android watches I’ve tried, this one clearly has enough power for daily tasks. I never had a moment where I thought “this watch is slow” during normal use like checking messages, changing songs, or starting workouts.

For fitness, it covers all the basics: walking, running, cycling, gym sessions, etc. GPS accuracy is decent for casual use; it’s fine for tracking runs around the neighbourhood or counting steps, but I wouldn’t rely on it as the ultimate reference for marathon training. Heart rate tracking during steady workouts seems consistent with what I’ve seen on gym machines and other wearables I’ve used. It also gives you rings to close each day, which is simple but surprisingly motivating.

On the smart side, notifications, calls, and Apple Pay work very well. Messages appear quickly, you can reply with short answers or dictation, and being able to tap your wrist to pay on public transport or at the supermarket is genuinely handy. It reduces how often you pull your phone out, which is nice both for convenience and for not flashing a phone in busy areas. Siri is there and usable for quick timers or reminders, even if it’s not perfect.

Health features are present but not as advanced as the top-end Apple models. You get sleep tracking with a daily score, heart rate alerts, sleep apnoea notifications, temperature sensing for cycle insights, and safety features like fall and crash detection. For most people, that’s already plenty. If you specifically want ECG or blood oxygen readings, though, this SE 3 is not the right one. So overall: it’s a solid all-rounder that handles normal life and casual fitness well, but it’s not a pro athlete tool or a medical device.

The Apple Watch SE 3 GPS 40mm is basically Apple’s mid-range watch: no cellular on this version, but all the key smart and health features. You get GPS, heart rate monitoring, sleep tracking, fall and crash detection, water resistance, and a bunch of workout modes. It also supports Apple Pay, notifications, calls when your phone is nearby, and all the usual Apple apps. It has 64 GB storage, which is plenty if you like syncing music or podcasts for runs without your phone.

This model is the Midnight aluminium case with the Midnight sport band in M/L, which officially fits 150–200 mm wrists. On my roughly 17.5–18 cm wrist, the 40 mm looks like a normal watch, not a big tech brick. It’s light enough that I forget it’s there most of the time, including during sleep. If you’re used to chunkier smartwatches or older Fitbits, this feels a bit more compact and cleaner on the wrist.

Feature-wise, Apple has crammed in most of the stuff regular users care about: sleep score, heart rate alerts, cycle tracking, temperature-based insights, safety alerts, and all the usual fitness modes. It also supports the new Apple Intelligence stuff (Workout Buddy etc.) when your iPhone is nearby, which is a nice extra if you like guided workouts or data nudges, but honestly not essential to enjoy the watch.

In practice, the SE 3 feels like the watch for people who don’t want to research for a week. You buy it, pair it, and it just works. The downside is it’s clearly built for iPhone users only. If you’re on Android, forget it; this is useless to you. Also, if you’re into extreme sports or long-distance events, the battery and GPS won’t be enough for very long outings compared to dedicated sport watches from Garmin or Coros.
