Huawei Watch GT 3 SmartwatchThe Huawei Watch GT 3 Smartwatch is a fitness-oriented smartwatch that looks great, and feels fast and responsive thanks to a new processor. It's packed with an impressive array of health tracking tools too, and offers truly remarkable battery life – particularly if you opt for the larger 46mm version.That longevity doesn't come at the expense of features, and the watch's array of biometric sensors track heart rate, SpO2, skin temperature, stress, and sleep. Huawei has given its optical heart rate monitor an upgrade this time around, and the results are impressive; changes are detected quickly during intense interval training sessions, and accuracy rivals that of dedicated running GT 3 Smartwatch.There's support for five satellite navigation systems as well, which should make for more accurate location tracking in areas where there's a limited line of sight between you and the sky. In our tests it wasn't quite as accurate as Garmin's GPS when it came to mapping out our pre-measured route, but was definitely sufficient for recreational running.The Huawei Watch GT 3 Smartwatch supports over 100 sports (both indoor and outdoor) but really comes into its own when you're running. The 'AI trainer' tool lets you set a goal and a deadline, and then creates a training plan that adapts on the fly according to your performance. It's a well executed tool that's easy to use, and is particularly well suited to new runners wanting to achieve their first milestones.The GT 3 Smartwatch on-board microphone is also a real boon for runners, allowing you to make and receive calls via Bluetooth without reaching for your phone. There's no eSIM, so you can't use this feature without your handset, but it's extremely simple to use and particularly helpful in emergencies.It's a shame that there's no support for contactless payments though. It would be a natural fit for this type of general purpose GT 3 Smartwatch, and we really felt its absence during testing.The Huawei Watch GT 3 Smartwatch app is available for both Android and iOS, but in order to get the latest Android version we had to download it through the Huawei AppGallery rather than direct from Google Play. It was a minor inconvenience, but one we'd rather avoid.Overall, this is an excellent device that takes the best features from Huawei's earlier models and puts them together in a stylish, refined package. If you're on the lookout for a great all-round smartwatch, it's easy to recommend – particularly at such a reasonable price. It's only a shame that it's unlikely to launch in the US...
