Xiaomi makes some of the best-value wearable tech around (case in point: Mi Band 4), and the Amazfit GTR stands out for its aesthetic design, incredibly long battery life, GPS, sleep tracking and choice of sports modes that include swimming.

Recently announced in China, and available in the UK now via GearBest, the GTR is a classy-looking waterproof (5ATM) sports watch with a 1.39in (454x454, 326ppi) AMOLED display with Gorilla Glass, a stainless steel or aluminium case, a choice of premium bands and a selection of more than 100 customisable watch faces.

Moreover, it offers 12 sport modes, including pool/open water swimming, running, cycling and walking, and uses a continuous heart-rate sensor for more accurate activity tracking.

The smartwatch functionality is limited compared to some more expensive watches, but you can still get all your notifications - messages, incoming calls, apps and so on - right on your wrist.

Xiaomi claims the 410mAh battery can last up to 72 days with basic usage, and 145 days on standby, but battery life is largely dependent on your usage. A more realistic - but still very good - scenario is around 24 days for most users.

These metal variants of the Amazfit GTR cost 999 RMB in China, which is around £116, but they have yet to officially launch in the UK where they will likely have an inflated price.

You can pick up the GTR on GearBest for £122.40, which is 17% off its usual price of £147.43. This is for the 47mm version, though a 42mm version will also be available.

By default GearBest may show you pricing in US dollars, but you can switch to your local currency from the drop-down menu at the top of the page.

Choose between an aluminium alloy or stainless steel case. GearBest is also stocking a stainless steel strap in silver or black for the GTR at £8.12.
