Best in Class

Our Verdict

The Galaxy Watch is Samsung's most refined smartwatch due to its helpful fitness tracking and four-day battery life – if you opt for the larger 46mm size that we liked and recommend. All of this is packaged inside a sophisticated-looking circular silver-and-black smartwatch that has a rotating bezel for effortless menu navigation. Be warned, third-party apps are lacking and its iOS support is limited if you're using an iPhone. This is best for Samsung fans.

For

  • Impressive four-day battery life
  • Great core smartwatch software
  • Rotating bezel cycles through UI
  • Looks like a real wrist watch

Against

  • Proprietary wireless charger
  • Bixby proven to be terrible again
  • No Google Maps, WhatsApp, FB Messenger

Update: The Samsung Galaxy Watch has edged out the Apple Watch 3 to claim the title of TechRadar's best smartwatch in the world.

The Samsung Galaxy Watch is one of the most refined smartwatches you can buy today, with an aesthetically pleasing design, cohesive user interface and, importantly, four-day battery life.

It’s everything the Apple Watch 3 is not – for better and worse. Let's start with what's better. The Galaxy Watch looks and feels like a high-end wrist watch, with a circular stainless steel case and decorative bezel. It’s both stylish and functional because, like the previous Gear S3, the bezel rotates to cycle through its various on-screen menus.

This is the most satisfying way to navigate a smartwatch. Your fingers won’t cover up the watch’s small, hard-to-accurately-target touchscreen (an issue with any smartwatch), and it’s an idea exclusive to Samsung’s newer watches. 

You won’t find rotating bezels supported by Google’s Wear OS, while Apple’s watchOS uses a less intuitive rotating digital crown button on the side. This is one of two reasons why the Galaxy Watch runs Samsung’s Tizen software, not Wear OS.

To see the Samsung Galaxy Watch in action, watch our hands-on video below:

The other reason for the Tizen operating system is battery life. We found that the larger 46mm Galaxy Watch lasted a solid four days with normal use, during which we checked messages, fetched constant notifications, tracked workouts, played Spotify, and talked to Bixby, Samsung’s mostly terrible AI. Samsung says the smaller 42mm Galaxy Watch lasts three days.

The big difference between the Galaxy Watch and the Gear S3, besides an extra day of battery, is that it’s more fitness-focused, thanks to additional sensors and a revamped Samsung Health app. It auto-detects six of (an expanded) 39 exercises – and still helpfully nudges you when you’re too sedentary, and it has a fairly accurate sleep tracker. It’s also now waterproof down to 50 meters, matching the Gear S3 Sport 5ATM rating in a more adult design.

The Galaxy Watch does inherit problems from previous Gear watches, however – and what's bad is almost all software-related. Samsung’s core apps are polished, sure, but the Galaxy Apps store lacks critical third-party apps, notably Google Maps, Facebook Messenger, and WhatsApp. The Bixby voice assistant is here, but it’s no better than S Voice at understanding us, and Samsung Pay doesn’t use Magnetic Secure Transmission (MST) despite the fact the Gear S3 did.

The Samsung Galaxy Watch is very much the Samsung Gear S4 that never was. It’s an iterative update, one that adds fitness software, new sensors, and extra waterproofing to everything we liked in the Gear S3 Classic and Gear S3 Frontier a year and a half ago. 

It’s a big, but sophisticated-looking smartwatch in two sizes that ends up being great to wear for notifications and exercise – if you don’t want the best Garmin watch for super-serious fitness tracking. Those are key reasons a lot of people we talk to wear a smartwatch: notifications, fitness, and light app usage. Anyone who wants something more out of the Galaxy Watch is measuring Samsung’s best up against a smartwatch that won’t exist until 2019 or 2020.

Samsung Galaxy Watch release date and price

  • Launched on August 24 in the US and September 6 in the UK
  • 42mm Rose Gold or Midnight Black watch costs $329 / £279
  • 46mm Silver watch costs $349 / £299, less than Gear S3 at launch
  • LTE version exists, but only on T-Mobile in the US so far and $50 more

The Galaxy Watch launched in the US on August 24, the same day the Galaxy Note 9 came out, and in the UK on September 6. Those in Australia will have to wait until some point in October to be able to buy the watch.

It’s actually cheaper than the Gear S3 was at launch, if you opt for the smaller size. It’s $329 / £279 for the 42mm version, and $349 / £299 for the larger 46mm size, which we recommend. When it first came out the Gear S3 cost $349 / £349 (around AU$475), and only came in one size. 

The LTE version of the Galaxy Watch costs $379 for the 42mm model and $399 for the 46mm version through T-Mobile; other US carriers like AT&T, Sprint, and Verizon will sell it later in 2018. In the UK, the LTE watch will be available later this year and it'll be exclusive to EE but we don't currently having pricing or launch date news.

Sizes and design

  • Looks like a real wrist watch compared to the Apple Watch
  • Larger 46mm size looks fine on our medium-sized wrists
  • Circular screen and rotating bezel make it stylish, functional and durable
  • Screen takes a half a second to refresh the time and stats when woken up each time

The Galaxy Watch comes in two sizes: the larger 46mm size in a two-toned silver-and-black color scheme, and the smaller 42mm size in either straight-up Midnight Black or Rose Gold. We tried on both sizes, and recommend the 46mm version for its larger battery and bigger touchscreen – it looks just fine on medium-sized wrists if you don’t mind a slightly bigger watch.

It’s more of a fashion statement than the understated Apple Watch. It’s big, circular, and meant to look like a wrist watch. We got compliments on its design when wearing it out; there was a lot of surprise that this was a smartwatch in a sea of people wearing the Apple Watch. It stands out.

There’s less variety when it comes to the case colors and included straps. The silver-and-black 46mm watch has three 22mm strap options: Onyx Black, Deep Ocean Blue, and Basalt Grey. The smaller black or rose gold 42mm watch has more 20mm strap variety: Onyx Black, Lunar Grey, Terracotta Red, Lime Yellow, Cosmo Purple, Pink Beige, Cloud Grey, and Natural Brown. Samsung sells extra straps, and any interchangeable 22mm or 20mm will work if you want to change up the style from day to day.

The 1.3-inch Super AMOLED screen (1.2-inch on the 42mm watch) is bright and color-rich, as we’ve come to expect from Samsung’s stellar display technology. It’s easy to see everything, even during an outdoor run, thanks to adaptive brightness settings. And its smart use of blacks, especially in the background, burns fewer pixels on the 320 x 320 resolution. The one downside is that the screen is slow to update when it’s woken – the time and steps show old figures for half a second. It’s like you’re literally waking the watch up from a nap and it’s taking a moment to come to its senses.

The ornate and functional rotating bezel has a third characteristic: it makes the Samsung Galaxy Watch durable. Take it from us – we’ve broken the exposed Apple Watch glass screen more than once. There’s protection here for the screen, with military-grade durability and Corning Gorilla Glass DX+ that prevents the display from getting scratched, according to Samsung.

Two physical buttons adorn the Galaxy Watch, and while they’re on the right side of the case, Samsung has wisely offset them from the usual center location, which means they’re not prone to accidental presses against your bent wrist as on other smartwatches. This is a well-engineered watch – at least during the day.

You’ll want to wear this watch to bed for its helpful sleep-tracking capabilities, but be warned: it’s large and cumbersome to leave strapped to your wrist the entire night. The 46mm version is an ever-present 63g, and it can feel like a rock tethered to your wrist. This is the one (and only) area in which you’ll be in better shape with the 42mm version, which weighs 49g.
