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 quick list
The best watch overall
Despite the upgrades of the Series 10, the Apple Watch Ultra 2 remains the best smartwatch on the market. It's got an incredibly rugged design, brilliant battery life, and a vibrant display. Just remember you'll need an iPhone to use one.
The best cheap Apple Watch
The second-generation Apple Watch SE does almost everything you could expect of a standard Apple Watch (excellent health and workout metrics, seamless iOS integration) with a few cost-cutting measures like nylon backing rather than stainless steel.
The best Samsung watch
The Samsung Galaxy Watch Ultra is top of the list because it does everything you want a Samsung watch to do. It runs Wear OS 5, offers advanced health features such as ECG and blood pressure monitoring, has Samsung's biggest battery life, and shares many of the Apple Watch Ultra 2's qualities. Top choice for most Samsung users.
The best Google watch
The Google Pixel Watch 3 offers the same sleek build as its predecessor, with an all-new larger display. The new display is also brighter, and the battery life has been increased, now offering up to 36 hours.
The best Wear OS watch
New for 2025, the OnePlus Watch 3 delivers even more astonishing battery life than its predecessor at 120 hours, and has new health features. It retains that classic look and has the best battery life of any Wear OS watch on the market.
The best cheap watch
Also new for 2025 is the stunning Amazfit Active 2, which delivers formidable performance and features for just $99. It works with both iPhone and Android and has up to 10 days of battery life, scoring a full five stars in our review.

The best watch overall
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 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 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.

The best Google watch
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.

The best Android smartwatch
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 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.

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.
