Compatibility: iOS
Display: 1.9" OLED
Processor: Apple S9
Onboard storage: 32GB
Battery: 36 hours
Charging method: Wireless
IP rating: Water-resistant to 100m
Connectivity: Wi-Fi, Bluetooth, NFC, LTE, Ultra Wideband

Reasons to avoid

-
Battery life, while improved, could still be better
-
Ultra Wideband only works with iPhone 15 and 16

The Apple Watch Ultra 2 is the ultimate smartwatch with one of the best screens we've ever seen on a wearable, with its sumptuous Retina Display OLED commanding up to 3,000 nits of brightness. It's bigger and bulkier, than the standard Apple Watch, and has a faster S9 processor, enabling that excellent Double Tap gesture available on the Series 9 below. In all other respects, it's identical to its predecessor, the original Apple Watch Ultra

It could still offer better battery life (despite surpassing the regular Apple Watch) but a powerful and accurate GPS is great for exploring, especially with watchOS 10's improved hiking waypoints feature, plus it's a working dive computer with the Oceanic Plus app. 

Despite the launch of the Apple Watch Series 10, this just about beats the latest Apple flagship to retain its title thanks to its hefty battery life and rugged design. 

During testing, we easily found this to be the most capable wearable that the brand has ever made. Unfortunately, it is limited by its reliance on the iPhone and its high price. However, when looking at the smartwatches on this list in a vacuum, it is the best smartwatch from a technical standpoint. As you can see in the specs table below, it's got the biggest, brightest screen, it can dive the deepest underwater, and its case is comprised of ultra-hard titanium.

IP rating: Water-resistant to 50m

No always-on screen or ECG compared to higher-priced watches
-
Nylon back

The Apple Watch SE 2 is arguably the best Apple Watch for most people, as it’s a lot more affordable than the Apple Watch Series 10, yet has most of the core features for those models, and even the same chipset as the Series 8.

The main things it lacks are an always-on display, ECG, and blood oxygen tracking from the 8 (although the Apple Watch Series 9 and 10 are now being sold without blood oxygen tracking), and the Double Tap feature from the 9, but the Apple Watch SE 2 still has a wide range of health and fitness features, plus potentially life-saving additions like Car Crash Detection.

It’s also powerful, has impressive battery life for a proper smartwatch, and is very light and comfortable to wear. So it strikes a superb balance between price and performance and is a great relatively affordable pick.

The best Samsung smartwatch overall

Specifications

OS: Wear OS (One UI Watch 6)
Compatibility: Android
Display: 480 x 480 px full-color AMOLED
Processor: Exynos W1000
Onboard storage: 32GB
Battery duration: Up to 100 hours
Charging method: Qi wireless charging
IP rating: IP68 + 10ATM
Connectivity: Wi-Fi, Bluetooth, GPS

Reasons to buy

+
Powerful fitness features
+
Durable and tough

Reasons to avoid

-
Relatively pricey
-
Optimized for Samsung phones

The Samsung Galaxy Watch Ultra is, from a technical standpoint is Samsung's biggest and best watch yet. It lasts longer, is more powerful, more durable, and is radically different in design from the other Samsung watches in its lineup. It's sat on a conspicuous titanium cushion and offers powerful outdoor-focused features.

A larger Super AMOLED display is sharp and clear, as well as able to handle very bright outdoor scenes. Performance-wise, it's fast although you'll reap the most benefits when paired with a Samsung smartphone. There's no iPhone support here either, but it's very much Samsung's version of Apple's successful Ultra line. 

Besides SmartThings integration, the highlights here is the updated chipset, the Exynos W1000, its durability, accurate GPS features, and Samsung's cool ability to monitor your body's muscle and fat composition. 

It's bordering on the ultimate fitness tool with extensive sleep tracking also helping you get the most from yourself every day, but we found it big and heavy to wear overnight during our tests.

The Google Pixel Watch 3 is the latest iteration on Google's classic smart watch design for 2024. It retains the sleek, modern, circular form factor that made the first two great, but now comes with an added 45mm size option. There are some fantastic optimizations built into Wear OS for the larger display, too. 

The band attachment system sadly hasn't been improved from previous models. However, the chip is still performant and it delivers everything you'd expect from a Google wearable. It's the perfect companion to the Pixel smartphone, and will even work well with other non-Samsung Android devices. 

That minimalist design is still an absolute classic, and sure to catch the eye on your wrist. With battery saver enabled, the Pixel Watch 3 now delivers up to 36 hours of use time, matching the Apple Watch Series 10.

Looks great

Reasons to avoid

-
Single size

Rotating crown not used

The OnePlus Watch 2 is an excellent all-rounder smartwatch, knocking the TicWatch Pro 5 from this place in the list, and an outstanding Pixel Watch alternative.

It has a lot going for it. For one thing, it uses the mighty Snapdragon W5+ Gen1 processor, so performance is good, and it also runs a second operating system, which it switches to when needed, in order to prevent unnecessary battery drain. That's how it gets to its impressive 100-hour battery life: clever use of its dual chipset. 

It also offers very accurate fitness tracking metrics, which we tested during forest walks in Finland against the Garmin Epix Pro. It looks great on-wrist, too, with leather strap options, a design based on analogue chronographs, and a few cool color choices such as Nordic Blue.

The best cheap smartwatch

CMF Watch Pro

The best cheap system-agnostic smartwatch

Specifications

OS: Nothing
Compatibility: iOS 13 and above, Android 8.0 and above
Display: 1.96-inch 410 x 502 AMOLED
Processor: Snapdragon Wear 4100
Onboard storage: 8GB
Battery duration: 13 days
Charging method: Qi wireless charging
IP rating: IP68
Connectivity: Bluetooth 5.3, GPS

Reasons to buy

+
Large display
+
Great battery life
+
Very affordable

Reasons to avoid

-
Some small connectivity issues
-
Overly simplistic

The CMF Watch Pro by Nothing is a very cheap, very attractive smartwatch that offers a lot for the money. It's got in-built GPS, up to 13 days of battery life, and in our review we mentioned the design was great, both in software and hardware. If you want a simplified smartwatch with a few health metrics, this is the one to get.

The downsides? With that low price point, of course, comes some missing features. It's never going to be as stacked with third-party apps or as versatile as an Apple or Samsung Galaxy watch, and you have to go through the rigmarole of manually adding contacts before calling them on the watch. The OS is pretty minimal, as one might expect from Nothing.

However, if you're looking for a cheap do-it-all watch that still looks attractive, you could certainly do a lot worse. The CMF Watch Pro is well-built, attractive and simple to use, and will certainly pick up a cult following.

How to choose the best smartwatch for you

Unfortunately, your choice of smartwatch often depends on your choice of phone, as not all wearables are compatible with competitor devices. Apple Watch only works with Apple iPhones. Samsung and Google watches, and other Wear OS devices, only work with Android devices, but you can use a Samsung watch with a Google phone and vice versa.

Fitness tracking wearables from Fitbit will work with any device and synchronize with the Fitbit app, but those devices tend to focus more sharply on fitness features, and don't offer all of the robust apps and services you'll find on other smartwatches. 

Most wearables will get about a day of battery life, which will be disappointing if you're converting from a Garmin watch that lasts weeks. You can find a few watches that last longer on this list. 

Finally, smartwatches can be expensive, and frankly they don't offer much value for what you pay. Before you spring for an Apple Watch Ultra, you might ask if you are really going Scuba diving this year, or if you're just going to check your text messages without disturbing your dinner mates. 

Can you use Apple Watch with an Android phone?

The first thing to check is whether your phone is compatible with the smartwatch you want. You can't use an Apple Watch with an Android phone, as all the functions of watchOS require iOS to interface with. 

You can use a Fitbit or Google Pixel Watch with an iPhone, but without Android or Google accounts, your experience will be sorely diminished. Samsung and Huawei also require handset-watch synergy to operate at their best. 

However, many devices like Garmin watches and the CMF Watch Pro by Nothing require nothing more than their own apps to work, meaning you can use them with either handset just fine. 

Which is the best smartwatch?

The best smartwatch changes all the time, but typically you'll find an Apple Watch or Samsung Galaxy smartwatch topping the list, as these tend to be packed full of high-end features and polish.

How we test smartwatches

Every smartwatch on this list has been fully and extensively reviewed by the expert team at TechRadar, so we know exactly what makes them tick.

Our review process involves using the devices as if they were our own personal wearables, ensuring every smartwatch gets fully tested in the real world. A comprehensive sweep of features takes place, and usage is varied over a week to give us a clear idea of how battery life performs.

When testing in-house, we generally look at how accurate the GPS is on each smartwatch by testing it against an industry leader such as the Garmin Epix Pro. Likewise for workout metrics. We also rank how usable the watch's operating system is, whether it supports third-party apps, and where it sits in the market. For example, a cheap watch with fewer features is more likely to get four stars than a feature-stuffed premium watch that isn't worth the expensive price. 

Using that knowledge we've then ranked them, factoring in their value, design, features and performance to get an overall star verdict.
