GARMIN FENIX 6X SOLAR £850

Men landed on the moon with less technology than you can now strap to your wrist. The Fenix 6X contains so many GPS tracking and fitness monitoring functions that it would require this entire Gear Guide to list them all, but here are some of the best bits. The battery lasts several days even when tracking a route by GPS, and the solar charging helps keep the battery topped up. If you’re a budding athlete, or just want to get fitter, the super tough Fenix offers myriad training profiles, pulse monitoring and even blood oxygen level measurements to help you finetune your training.

VERDICT Just scratching the surface reveals a lot to be impressed by, and there’s so much more to discover in the Fenix 6X.
