Your buying guide to the best smartwatches in 2017

Why do I need a smartwatch?

There's an interesting theory that smartwatches are to the smartphone what wristwatches were to the pocket watch. Picture the way the average gentlemen used to have to rummage through his pocket for his watch prior to the 20th century. Now skip forward 100+ years and the average smartphone user still has to dive into his/her pocket to check their phone.

Read: The best phones you can buy in 2017

The kicker now is that your smartphone holds far more information than a pocket watch ever did, yet all of which is still locked into your pocket.

Smartwatches aren't for making phone calls, although some can do this, but instead they provide a quick and easy way to check what notifications are on your smartphone, so you can decide whether it's worth delving into your pocket or searching around your bag to fetch your smartphone or not.

What type of smartwatch should I look for?

There are two type of smartwatch around at the moment: those with a colourful touchscreen like would find on your phone, and those which combine a regular analogue watch with smart features - we call them 'semi-smartwatches'.

The latter we class as a semi-smart device and normally gives you information via a small LCD screen, LEDs or even smaller hands on the watch face.

While a fully-fledged smartwatch can do a lot more, the juice guzzling screen results in a short battery life. Semi-smart watches benefit from longer battery life with some even having separate cells for the watch and smart features.

If you're an Android user then an Android Wear smartwatch is the obvious choice but it's not necessarily the best for everyone. Google's OS tweaked for wearables also plays nicely with iOS but with cut down functionality so iPhone owners will get more from the Apple Watch.

Others have an entirely different system such as Pebble's range of devices and some even work with Windows Phone like the Vector Watch. Samsung is sticking with its own Tizen, too, so there's something for everyone here. Also see: Qualcomm Snapdragon Wear will make all kinds of wearable devices better.

What makes a good smartwatch?

When testing for what is the best smartwatch, the important factors to consider are how much of your smartphone's functionalities can it perform, and how well does it handle each task, the final attribute is obviously style - it's still bling after all.

You'll also want to make sure it's compatible with your smartphone - some are only for iPhone or Android while others support most phones. Note that Android Wear now has iOS support but the experience is cut down in comparison.

Some smartwatches use different software such as the Gear S3 which runs Tizen, Samsung's own OS - it's a legitimate alternative to Android Wear.

As is stands, you'll need to pick a watch with more limited functionality if you want long battery life while ones which can do all sorts will typically last a couple of days.

Fitness fans will want to look for a device with a heart rate monitor and built-in GPS, although the heart rate monitors are often poor.

We consider the important factors of a smartwatch to be level of notification detail, battery life, style, water resistance, compatibility with a range of devices/smartphones, plus additional features such as microphones and Wi-Fi support so you don't have to connect to a phone for full functionality.

With very similar, if not identical, hardware on offer with many of the Android Wear smartwatches, a large part of the decision will come down to design and price.

Smartwatch security warning

According to a new report titled Friend or Foe? Your Wearable Devices Reveal Your Personal PIN, it isn't at all difficult for a hacker to figure out your PIN or password utilising motion sensor data from your wearable, with researchers getting it right around 80 percent of the time. 

Their advice is for us to create a certain kind of noise data, or to input our PINs and passwords using the other hand.

But we have to say, we do that anyway... at least those of us who are righthanded. We fix our watch strap to our left arm using our right hand, and enter our PINs and passwords using our right hand.

  • Reviewed on: 22 May 2017
  • RRP: £329

The Huawei Watch 2 is no-doubt a huge improvement over the first-generation Huawei Watch despite trading in the classic look for something a little sportier. The double-chrome design gives it a premium look, although it’s let down a little bit by cheap-looking removable plastic straps.

It’s the hardware that really sets the Watch 2 apart: it boasts optional 4G connectivity, GPS, Wi-Fi and Bluetooth, allowing for use without a connected smartphone. The array of built-in sensors provides in-depth fitness tracking, allowing for a more holistic view of your exercise regime, although there are small issues that need ironing out.

The new Apple Watch Series 2 takes the main complaints about the original - slow operation, lack of GPS, lack of official waterproofing, short battery life - and solves or at least improves them systematically. If you're into fitness tracking with a sprinkling of notifications and superb integration with the iPhone, this is an almost perfect wearable for you... although, being greedy, we'd still like an even better battery life, and the price remains pretty steep. We thought long and hard about whether to give the Apple Watch Series 2 five out of five, and it was a close-run thing. But those two issues are still, just, keeping it from a perfect score. Great wearable, though, and the only one we've seen that feels like it has any chance at all of taking wearables into the mainstream.

  • RRP: TBC, US$349

If you are definitely going to be able to charge it every night and you don’t mind paying for the LTE functionality you may not be able to use, then the LG Watch Sport is one of the best Android smartwatches ever made.

Android Wear 2.0 is very good and is definitely the best choice over Tizen unless you’re using a Samsung phone.

But the Google Assistant is weak for a headline feature and the battery life just isn’t good enough. Smartwatches that limp towards lunch on Day 2 still please, but the fact the Watch Sport sometimes dies before you’re home on Day 1 isn’t good enough.

You shouldn’t have to turn off half the functions of the product to make it last the day. It’s is one of the better smartwatches out there, but like most of them, it’s not without its infuriating flaws.

  • RRP: £249

Based on our time with the Samsung Gear S2, we think it's a sleek smartwatch with an attractive design. It offers fairly standard smartwatch features like fitness tracking, but also includes some rather interesting features including a rotating bezel used for navigating the UI and enhanced app capabilities. At £249, it sits itself alongside the likes of the Moto 360 2, and we think the Gear S2 is a great, if not better option for Android users – especially with a custom, intuitive UI.

There's no doubt that the Fossil Q Founder is a well-made and good looking Android Wear smartwatch which is also a competitive price. The hardware on offer is good, although some may miss the heart rate monitor and GPS. As much as we love it, the flat tyre effect of the screen is a big drawback stopping it being really great.

6. Samsung Gear S3 Frontier

Samsung Gear S3 Frontier
  • Rating: ratingsratingsratingsratingsratings
  • Reviewed on: 8 December 2016
  • RRP: £349, US$349

The Gear S2 arrived on a deserved wave of hype, but for some reason we aren’t overly excited about this new Gear S3 Frontier. The only thing it actually adds is GPS, and at a £100 cost it’ll definitely put some people off. The reduced functionality when not using a Samsung phone is also a turn-off, despite the software being easier and more intuitive than Android Wear.

The problem isn’t entirely the S3’s fault, it’s in the inherent limitations of smartwatches. You’ll always need a smartphone to finish the majority of tasks, and added to the fact that this is practically a repackaged Gear S2 means not much new ground has been broken. If you want a smartwatch and can afford to spend £349, this is the one to get. It just isn’t essential.

There's a lot to like about the LG Watch Urbane with it's handy Wi-Fi connectivity and the welcome new version of Android Wear. Since it's essentially the same device as the G Watch R in terms of hardware, your purchase really hinges on the design. It is expensive and bulky so we can't see it appearing to the masses so the G Watch R is still our recommended choice.

Available for under £200, the Motorola Moto 360 Sport is one of the best smartwatches for fitness. You get the some of the regular 360 style in a design which is practical for activities like running. The GPS tracking is accurate but it's shame the same can't be said of the heart rate monitor and we still find the 'flat tyre' on the screen an eyesore. A solid effort but hard-core fitness fans might need something which is more in-depth.

Although it's pricy, the Huawei Watch is best Android Wear smartwatch on the market with its absolutely stunning design and exquisite build quality. There's still work to be done though as the watch lacks GPS, the heart rate monitor doesn't work very well and the charger is bit fiddly.

If you’re not fussed about a full on touchscreen smartwatch, the Withings Steel HR is stylish, well-made and offers excellent battery life. We’re glad to see the addition of the heart rate monitor and the screen for smart features, even if they are basic. A great semi-smartwatch for the price.

The SmartWatch 3's biggest strength is its built-in GPS, but you'll still need a smartphone for driving directions. It's also great to see a standard USB charging port. The transflective screen is a good idea, but in practice battery life is no better than other smartwatches with better-looking screens. Ultimately, unless you're on a fixed budget, the G Watch R is the better choice. If you can't afford that, wait a few months: the price is bound to drop.

If you feel comfortable spending £165 to get a stylish watch (albeit rather a chunky one) with smart features, and are confident that you won't miss GPS or heart rate monitor, you'll be pleased with the Phase. But for anyone questioning that price tag I'd recommend looking at Misfit's other trackers or waiting for the new Misfit Vapor smartwatch release.

The Pebble Steel may not have a high-res and colourful screen and the square design may not be for everyone, but we think it's stylish and the display has a retro charm which also provides excellent battery life. A good alternative to Android Wear if that's not your cup of tea.

The Fossil Q Grant is easily the best looking and well made 'semi-smartwatch' we've reviewed. It's both stunning and affordable although the plastic back which shows is a shame. Smart features including customised notifications and activity tracking work well but are fairly basic and limited. Our main issue is the connectivity issues with Android.

15. Vector Watch Luna

  • RRP: £299

It's good to see a company approaching the smartwatch differently and we like the design and style of the Vector Watch Luna. A month-long battery life is a real standout point but you'll have to be happy with the retro low-res display as a sacrifice. This is all acceptable but the device falls down when it comes to functionality with poor apps, fitness tracking and notification system. Things are improving over time with software updates but that's not really good enough at this price point.

  • Reviewed on: 16 August 2016
  • RRP: £289 (41mm), £299 (45mm), US$379 (41mm), $399 (45mm)

Looks-wise we're not at all keen on the huge, chunky and ostentatious Guess Connect: the Fossil Q Grant has a far subtler and more elegant design, and is less likely to bruise your child's face when you're having a cuddle.

But you may disagree, and if you can put up with - or are even charmed by - the Connect's brutal look, there's a strong feature set here to get your teeth into: it feels only a step or two down from a fully fledged smartwatch. With voice commands and the ability to pick up phone calls or have texts read to you, it's head and shoulders above the Fossil for sheer smartness.

For features, this is probably the strongest semi-smartwatch we've seen: activity tracking is the only significant chink in its armour. If that's a priority for you, plump for the Fossil Q Grant - which you may want to do anyway because it's also a lot cheaper and (in our view) more attractive.

There's plenty to like here, from the extremely good battery life and decent water resistance rating to that always-on time display. Heart rate monitors aren't a given in this class of wearable and swim-tracking is an unexpected bonus. And it looks ok, especially if you swap in a third-party strap.

But it feels cheap, and perhaps more worryingly, it isn't particularly cheap - the price tag isn't really low enough to compensate for the missing features (such as GPS) or the dim and sluggish display. We also find the watch face options rather poor, offering little useful information. Better deals may and indeed should become available (on Amazon it costs less in dollars than in pounds, which suggests the UK option is overpriced at present) but until then, we'd suggest looking elsewhere.
