This outdoorsy watch talks to all five major satellite systems (GPS, GLONASS, Galileo, QZSS and Beidou) at the same time with dual frequencies. This makes for the most precise positioning data and best signal, whether you’re scaling a rock wall, travelling deep in a forest or just running in the ‘concrete canyon’ of a city centre.

Unboxing is impressive, with a rugged waterproof case… that you might never use again if the watch stays on your wrist at all times.

The watch is chunky. Its 280x280 pixel sapphire glass screen is large and it’s deep (15.7mm). The watch is heavy – and yet, once you put it on, it’s OK. The design is impressively wearable – you don’t notice the weight when it’s on.

Charge the watch for the first time and a QR code appears on the screen for easy setup. You first need to download the Coros app, set up an account with a minimal amount of information (email, password, gender, height, weight) and then scan the QR code. It worked first...
