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 now available in the UK, 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. 

These metal variants of the Amazfit GTR cost 999 RMB in China, which is around £116, but UK prices are slightly more inflated, depending on which size and metal finish you choose. The options are Stainless steel, Titanium and Aluminum alloy.

The cheapest price right now comes from Geekbuying but for the 42mm version only, which costs £95.72 if you order from Hong Kong. There are separate shipping fees. If you choose to ship the 47mm option from Spain, it costs £111.67 with £5.51 in shipping, for a total of £117.18

Amazon has the second most competitive price on the 42mm option, where it's available for £99, while the 47mm option is available from £97.70.

GearBest was the first retailer to offer the GTR in the UK, where it sold for £122.40, which is 17% off its usual price of £147.43. Now with Cyber Monday upon us, the price has gone down further to £109.90 for both the 47mm and 42mm version.

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.

The Amazifit GTR also 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. 

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.

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. See our round up of the best smart watches of the year.
