Garmin's fēnix range is built for sport, with strong battery life and tracking. It costs a lot more than an ordinary smartwatch, so it is worth checking who it is for.

Our take: for most people a £300 smartwatch does everything they need. The fēnix is for people who want long battery life and serious training features. Buying last year's model can save about £200.
