G-SHOCK MUDMASTER GG-B100 £325

More than a watch, this G-Shock is a genuinely rugged and robust outdoor tool. Equipped with an altimeter, barometer, compass, thermometer, timer, stopwatch, alarm, step counter and more, it’s almost as smart as a true smartwatch – but with much longer battery life, thanks to an ana-digi quartz movement that doesn’t need recharging.

VERDICT An uber-tough outdoor watch with lots of useful on-the-hill functionality and a shock-proof, mud- and water- resistant design that will take plenty of use and abuse.
