Choosing the best smartwatch for you depends on a number of factors, most notably which platform and operating system you're using.

If you want the very best experience on iPhone, you'll be looking for an Apple Watch. Likewise, the best Android experiences tend to come from Wear OS and the likes of Google and Samsung.

While there are also some great platform agnostic options from the likes of Amazfit, our years of testing experience has taught us that the best way to choose a smartwatch is to pick the one that works best with your smartphone, while also considering a range of other factors.

We've reviewed every smartwatch on the market and have been testing these products for well over a decade. Each of the products is reviewed by a health and fitness expert and scored on design, features, performance, and of course value. We collate that data to bring together our picks, and you won't find any picks on here that we haven't reviewed.

There are, however, plenty that didn't make the cut. So whether you're looking for a new Apple Watch, Samsung Galaxy, or a great Wear OS option from the likes of OnePlus, here are all the best smartwatches you can buy in 2025, now featuring the new OnePlus Watch 3 and the fantastic Amazfit Active 2.

The best smartwatch overall

Specifications

OS: watchOS 11
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 buy

+
Large, bright display
+
Action button is very useful

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, 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 the S9 processor, enabling that excellent Double Tap gesture. 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 Series 10) but the powerful and accurate GPS is great for exploring, especially with watchOS 11's improved hiking waypoints feature, plus it's a working dive computer thanks to 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, it's got the biggest, brightest screen, it can dive the deepest underwater, and its case is comprised of ultra-hard titanium.

The best cheap Apple Watch

The best Apple Watch for iPhone users on a budget

Specifications

OS: watchOS 11
Compatibility: iOS
Display: 1.78" OLED
Processor: Apple S8
Onboard storage: 32GB
Battery: 18 hours
Charging method: Wireless
IP rating: Water-resistant to 50m
Connectivity: Wi-Fi, Bluetooth, NFC, LTE

Reasons to buy

+
Light and comfortable
+
Good battery life for price
+
Packs updated features compared to older cheap Apple Watches

Reasons to avoid

-
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 watch

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, 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 sits on a conspicuous titanium cushion and offers powerful outdoor-focused features.

A larger Super AMOLED display is sharp, clear, and 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 are 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.

Specifications

OS: Wear OS 5
Compatibility: Android 10 or higher
Display: 1.2" OLED
Processor: Qualcomm SW5100, Cortex M33
Onboard storage: 32GB
Battery: 36 hours
Charging method: Wireless
IP rating: IP68
Connectivity: Wi-Fi, Bluetooth, NFC, LTE

Reasons to buy

+
Elegant, classic watch-like looks
+
Even brighter display
+
New larger size

Reasons to avoid

-
Band switch system not improved
-
No blood oxygen sensing - yet

The Google Pixel Watch 3 is the latest iteration of Google's classic smartwatch 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.

Processor: Snapdragon W5/BES2800
Onboard storage: 32GB
Battery duration: Up to 120 hours

Best Wear OS battery life on the market
+
All Google’s third-party apps
+
Classic look
+
New health features

Reasons to avoid

-
Big and heavy
-
No LTE (yet)
-
Slight issues with swim tracking & sleep data interpretation

New for 2025, the OnePlus Watch 3 is an absolutely fantastic new Wear OS smartwatch. It builds on the very successful formula of our previous pick, the OnePlus Watch 2, with its bold, chunky design, impressive AMOLED display, and leading battery life.

In our testing we found the OnePlus Watch 3 is definitely good for its 120 hour battery life claims, and loved its impressive suite of health and communications features.

The classic, round look stands out from other Wear OS options, but you'll still get Google's entire suite of apps and everything else you'd expect from a Wear OS smartwatch. It's cheaper than the Pixel Watch 3 (at least at list price), and comes with a rotating crown and a screen we described as "sumptuous."

There's good news too, a smaller version and LTE support is on the way later this year.

The best cheap smartwatch

The best cheap system-agnostic smartwatch

Specifications

OS: Zepp OS
Compatibility: Android 7.0 & iOS 14.0 (and above)
Display: 1.32’’ AMOLED Display 466 x 466px
Battery duration: 10 days
Charging method: Wired connector
IP rating: 5 ATM
Connectivity: Bluetooth 5.2, BLE, GPS

Reasons to buy

+
Brilliant classic design
+
Excellent health tracking
+
Very long battery life

Reasons to avoid

-
Slightly imperfect fit
-
Strength workout feature is clunky
-
NFC costs extra

The Amazfit Active 2 is an unbelievable smartwatch considering its $99 price tag.

We loved its classic, stainless steel design that stands out against other wearables on the market and really punches above the weight of its price point. Our reviewer loved that it's light and comfortable to wear, and the screen quality is excellent with solid brightness.

It comes with an impressive feature set of 164 sport modes, AI coaching, and extensive health tracking including daily Readiness Score and all the usual health metrics you'd expect to find in a smartwatch.

There are a couple of quirks in the strength training feature, but the battery life is exceptional and we found it easily offers its rated 5 days of normal use, if not more.

We also like the AI assistant, and the fitness and health tracking can easily keep up with our top smartwatch, the Apple Watch Ultra 2. Plus, it works with both iOS and Android. You can score NFC and a more premium display for an extra $30 too.

Here are some of the other smartwatches we've reviewed that don't make the cut:

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.

The best smartwatch for women vs men: Is there a difference?

There are no specific differences when it comes to smartwatches for women or men, but it's largely down to personal preference. One of your main considerations will be making sure the size of the watch fits your wrist; many smartwatches nowadays are far too large for slender wrists, and you won't want a device that disproportionate to your wrist size. To help you decide, take a look at the watch size options before buying, as many come in multiple sizes. When this is the case, we've listed the size options in our full reviews.

Some smartwatches do provide features specific to women's health, such as menstrual cycle tracking based on heart health and skin temperature. This isn't to say those watches can only be worn by women, nor that women have to use these features: most are opt-in, and easily disabled or simply not set up in the first place unless you choose to do so.

If you are going to use those features, it's always advisable to read the privacy policy of the watch you've just bought to get a better understanding of where your health information is stored, and who has access to it.

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 in 2024 is the Apple Watch Ultra 2, but it requires an iPhone to use. If you have an Android device, the best alternative is the Galaxy Watch Ultra.

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.
