Not everyone wants to spend the price of a weekend city break on a smartwatch. Whether you're tracking your steps, keeping an eye on your heart rate, or just want notifications without reaching for your phone, there's a solid crop of budget and mid-range options that punch well above their weight. This comparison focuses on three of the most talked-about picks right now: the Apple Watch SE 2, the CMF Watch Pro, and the Fitbit Charge 6. We'll be looking at health monitoring accuracy, smart features, battery life, and — crucially — whether they're genuinely worth your cash.

Apple Watch SE 2: The Safe Bet for iPhone Users
Design and Build
The SE 2 keeps the familiar rectangular Apple Watch shape with aluminium casing and the option of several band styles. It's lighter than the Series 10 and doesn't have the premium feel of the more expensive siblings, but it's solidly built and feels like a proper Apple product on the wrist. The display is bright and responsive — not always-on in this model, which is one of the key cost-cutting compromises Apple made, but it lights up fast when you raise your wrist. It's swim-proof and holds up well to daily wear and tear.
Health and Fitness Tracking
You get continuous heart rate monitoring, blood oxygen (SpO2) readings, sleep tracking, menstrual cycle tracking, and irregular rhythm notifications. The SE 2 also includes crash detection and fall detection, which are genuinely useful features for older wearers or those with active lifestyles. There's no ECG here — that's reserved for the Series lineup — but for most casual health trackers, the suite on offer is more than adequate. GPS is built in, so outdoor runs and cycle tracking are accurate without needing your phone nearby.
Smart Features and Battery Life
Running watchOS, the SE 2 benefits from the widest app ecosystem of any smartwatch. Apple Pay, Siri, Find My, and tight iPhone integration are all present and correct. Battery life is the one persistent grumble: expect roughly 18 hours with typical use, meaning you'll charge it every night. That's fine for most people but limiting if you want sleep tracking every night without thinking about it.
Who Should Buy the Apple Watch SE 2
If you're in the Apple ecosystem — iPhone, AirPods, MacBook — the SE 2 is by far the most seamless experience at this price tier. Android users need not apply; it simply won't pair. For iPhone owners who want Apple Watch without the premium price, it's hard to argue with.
CMF Watch Pro: The Spec-Sheet Shocker
Design and Build
CMF — the sub-brand from Nothing — has made a name for itself by offering specs that feel almost comically generous for the price. The Watch Pro sports a large 1.96-inch AMOLED display with a rotating crown that actually works smoothly, and the overall build quality is surprisingly premium for its price bracket. It's not going to win a luxury watch beauty contest, but it's modern-looking and comfortable for all-day wear. You also get some customisation via interchangeable straps and case accessories, which adds a bit of fun to the package.
Health and Fitness Tracking
Here's where the CMF Watch Pro flexes hard. You get continuous heart rate monitoring, SpO2 tracking, stress monitoring, sleep tracking, and over 100 sports modes. GPS is built in. The accuracy of the sensors is good enough for everyday fitness purposes — think step counting, general heart rate trends, and sleep stage breakdowns — though anyone wanting medical-grade precision will need to look elsewhere. The broader point is that you get a lot of health data collection for very little outlay.
Smart Features and Battery Life
Battery life is where the CMF Watch Pro genuinely surprises: the company claims up to 13 days with typical use, and real-world testing tends to land in the 9–11 day range depending on GPS and always-on display usage. That's a significant advantage over both rivals here. It works with both Android and iOS, though the deeper integrations — quick replies, app notifications — work better on Android. You won't get the smartwatch depth of watchOS or the Google integration of the Fitbit, but for basic notification mirroring and fitness tracking it does the job.
Who Should Buy the CMF Watch Pro
If your main priority is getting the most features for the least money, especially battery life and a sharp display, the CMF Watch Pro is a remarkable value proposition. It suits Android users in particular and anyone who hates charging their watch every night.
Fitbit Charge 6: The Health-Obsessed Tracker
Design and Build
The Charge 6 is a tracker rather than a full smartwatch — it's a slim band with a small vertical display rather than a square or round watch face. That might sound like a downgrade, but it has a real advantage: it's discreet enough to wear all the time, including in situations where a chunky smartwatch feels out of place. The build quality is solid, the screen is bright enough for outdoor use, and it comes in a few subtle colour options. It's not a showpiece but it's functional and comfortable around the clock.
Health and Fitness Tracking
This is Fitbit's strongest suit and the reason many people choose it over a full smartwatch. The Charge 6 includes an ECG sensor (one of the few devices at this price point to offer it), continuous heart rate monitoring, SpO2, skin temperature tracking, and a stress management score. It also tracks Active Zone Minutes, which is Fitbit's take on intensity-based cardio tracking tied loosely to WHO exercise guidelines. Sleep tracking is among the best in this price bracket, with detailed breakdowns of sleep stages and a readiness score in the morning. Built-in GPS rounds out the fitness picture. All this health data feeds into the Fitbit app, which remains one of the most polished wellness dashboards available.
Smart Features and Battery Life
Being a Google-owned product now, Fitbit integrates Google Maps turn-by-turn navigation and Google Wallet for contactless payments directly from your wrist — genuinely useful extras that most fitness trackers at this price don't offer. Notification support covers calls, texts, and app alerts. Battery life sits around 7 days, which is better than the Apple Watch SE 2 but behind the CMF Watch Pro. One catch: deeper features and longer history access require a Fitbit Premium subscription, which is worth factoring into your ongoing costs.
Who Should Buy the Fitbit Charge 6
Health-focused users who want reliable, clinically-relevant metrics — especially ECG and sleep tracking — in a slim, wearable form factor. It works with both Android and iOS and is a particularly good fit for people who want a fitness tracker first and a smartwatch second.

Alternatives to Consider
Budget pick: Xiaomi Smart Band 9
If even the CMF Watch Pro feels like more than you want to spend, the Xiaomi Smart Band 9 is a genuinely capable fitness band at a very low price. You get heart rate monitoring, SpO2, sleep tracking, and excellent battery life in a slim, lightweight band. It won't give you GPS or a full smartwatch experience, but for basic activity tracking it's hard to beat as an entry point.
Premium upgrade: Garmin Forerunner 265
If after reading all this you realise you want more — particularly if you're a serious runner or cyclist — the Garmin Forerunner 265 steps up with advanced training metrics, multi-band GPS, training load analysis, and Garmin's best-in-class battery life and durability. It's noticeably more expensive but built for athletes who use their watch as a genuine training tool rather than a lifestyle accessory.
Our Verdict: Which Should You Buy?
There's no single right answer here — each watch suits a different buyer — but here's how we'd cut it:
- Buy the Apple Watch SE 2 if you're an iPhone user who wants the full Apple Watch experience without the Series 10 price tag. The ecosystem and software quality justify the cost if you're already in Apple's world.
- Buy the CMF Watch Pro if you're on Android (or don't care much about app depth) and want the best combination of battery life, display quality, and price. It over-delivers for the money.
- Buy the Fitbit Charge 6 if health data is your top priority — specifically ECG, sleep tracking, and skin temperature — and you want a slim form factor that doesn't feel like wearing a computer on your wrist.
Our overall top recommendation for most people who don't already own an iPhone is the CMF Watch Pro: it offers the most complete package for casual users at a price that removes the risk from buying. But if you're serious about health metrics, the Fitbit Charge 6 earns its place emphatically.
