No heart-rate monitor ; Expensive ; Bulky design, still not fully circular ; Fickle charging cable

The Casio Pro Trek Smart WSD-F20 is a good smartwatch with features too niche for most people. But if you’re an outdoors enthusiast that loves checking out data from barometers and altimeters, or even tracking the way you’ve traveled, you’ll like what...

Reliably rugged ; Trusty on-board GPS ; Android Wear expandability

Middling battery life ; Offline maps of limited usefulness ; Apps and interface can be unintuitive

An Android Wear ticker with rugged ambitions, the F20 is closer to a re-shelled smartwatch than a proper off-grid companion

Rugged and water resistant ; Offline color maps ; Low power monochrome backup display

Full functionality requires an Android phone ; Not the fastest CPU

No cellular signal? No problem! This watch can help you navigate using offline maps and GPS

Tough as nails ; Dual-layer LCD screen ; Android Wear 2.0 ; Glorious watchfaces

Dodgy data logging ; Unintuitive UI ; Bleeds battery

A bullet-proof Android Wear soldier, this. But for outdoor tracking, you could do better.

Redelijk goede accuduur bij normaal gebruik ; Slim gebruik tweede display ; Voor hikers ideaal opladen met magnetische kabel ; Slim gebruik van de aanwezige sensoren voor hikers

Geen hartslagsensor
